Initial Sequencing and Analysis of the Human Genome

Nature, 2001 · paper · Biomedicine

Reports an international collaboration's draft sequence of the human genome, covering about 94% of it, and an initial analysis. It estimates roughly 30,000–40,000 protein-coding genes, only about twice as many as worm or fly.

Substance Table 1, BAC-end sequence column: "Total all libraries" gives "812,594/488,017/100,775", so clones with both ends sequenced (100,775) is smaller than the "Total of top eight libraries" subtotal ("805,320/484,278/297,997").
  • p. 7 Table 1, row 'Total all libraries', BAC-end sequence column
    100,775
  • p. 7 Table 1, row 'Total of top eight libraries', BAC-end sequence column
    297,997

Only the authors can say what is right here.

Judge's note: Read the column on the p7 image. The four library rows sum to the printed top-eight subtotal for all three components (805,320; 484,278; 297,997). The all-libraries row includes those eight, so its third component cannot be below 297,997; the first two components do rise (812,594 and 488,017). The footnote defines the three numbers the same way for every row and gives no different basis for the last row. The printed 100,775 is wrong; the correct value cannot be derived from the paper (300,775 is a guess), so the authors must supply it.

Substance Table 3: the 'Total human sequence (kb)' rows (20 centres plus Other) sum to 4,338,498, but the Total row prints "4,338,224" (274 kb less).
  • p. 9 Table 3, Total row, total human sequence (kb)
    4,338,224

Only the authors can say what is right here.

Judge's note: Read every row from a 4x render of Table 3 and checked against the layout text; all 21 values match and sum to 4,338,498. The table note explains only why the total differs from Tables 1 and 2 (padding characters, clones not used in assembly), not a row-to-total difference inside Table 3. Values are integers in kb, so rounding cannot account for it. The gap is tiny (0.006%) and it is not evident whether a row or the total is wrong.

Substance Table 3: the 'Finished human sequence (kb)' rows (20 centres plus Other) sum to 844,527, but the Total row prints "842,027" (2,500 kb less).
  • p. 9 Table 3, Total row, finished human sequence (kb)
    842,027
  • p. 9 Table 3, finished column rows
    284,353

Only the authors can say what is right here.

Judge's note: Read every row from a 4x render of Table 3 (46,560; 284,353; 175,279; ... 35,911) and checked against the layout text; the sum is 844,527. The table note addresses only differences from Tables 1 and 2. The text figure of 'more than 835 Mb' of finished sequence is a different (nonredundant, 7 October) quantity and does not explain the within-table sum. An exact 2,500 difference suggests a single wrong digit in one row or in the total, but which cell is wrong cannot be told from the PDF.

Substance Table 7, chromosome 17, sequence contigs: printed "4,339"; the column then sums to 149,761 against the printed All "149,821", and Table 8 gives "4,261" sequence gaps for chromosome 17, which with 138 sequenced-clone contigs (Table 6) implies 4,399.
  • p. 14 Table 7, chromosome 17, Sequence contigs: Number
    4,339
  • p. 14 Table 8, chromosome 17, Sequence gaps: Number
    4,261
  • p. 14 Table 7, All, Sequence contigs: Number
    149,821

Judge's note: Read all rows of Tables 6, 7 and 8 from 3x renders and the layout text. The sequence-contig column (chr 1-22, X, Y, UL) sums to 149,761, 60 below the All row, whereas the initial-sequence-contig column sums exactly to 396,913. For every chromosome except 6 and 17, Table 8 sequence gaps = Table 7 sequence contigs minus Table 6 sequenced-clone contigs. For 17: 4,339 - 138 = 4,201, but 4,261 is printed; 4,261 + 138 = 4,399, and replacing 4,339 by 4,399 makes the column sum exactly 149,821. Two independent checks point to the same digit transposition (4,399 printed as 4,339).

Substance Table 7, sequence-contig scaffolds: the chromosome and UL rows sum to 85,747, but the All row prints "87,757" (2,010 more).
  • p. 14 Table 7, All, Sequence-contig scaffolds: Number
    87,757
  • p. 14 Table 7, chromosome 10 row, scaffold Number
    6,886

Only the authors can say what is right here.

Judge's note: Read the scaffold Number column from a 3x render of Table 7 and the layout text; the 25 rows sum to 85,747. The same rows sum exactly to the All value in the initial-sequence-contig column (396,913) and, after the chromosome 17 fix, in the sequence-contig column, so an unlisted category is not the explanation and the legend offers none. Chromosome 10 ("6,886" scaffolds for 9,126 contigs) is out of line with the other chromosomes, but changing it to 4,886 still leaves the sum 10 short (87,747), so the wrong cell cannot be identified from the PDF.

Substance Table 8, chromosome 6, sequence gaps: printed "5,225"; Table 7 sequence contigs "5,547" minus Table 6 sequenced-clone contigs 292 gives 5,255, and the column sums to 145,484 against the printed All 145,514 (30 short).
  • p. 14 Table 8, chromosome 6, Sequence gaps: Number
    5,225
  • p. 14 Table 7, chromosome 6, Sequence contigs: Number
    5,547

Judge's note: Read Tables 6, 7 and 8 from 3x renders. Sequence gaps equal sequence contigs minus sequenced-clone contigs for every chromosome except 6 and 17 (17 is the Table 7 error in C023). For chromosome 6: 5,547 - 292 = 5,255, not 5,225. The printed rows (chr 1-22, X, Y, NA, UL) sum to 145,484; with 5,255 they sum to the printed 145,514, which is also the figure quoted in the text on page 15 ('145,514 gaps'). Evident digit slip: 5,255 printed as 5,225.

Substance Table 8, All row: total estimated chromosome size is printed "3,289" Mb, but footnote double-dagger defines it as "The sum of the five lengths in the preceding columns", which for the All row is 2,692.9 + 152.0 + 142.7 + 80.6 + 212 = 3,280.2 Mb.

  • p. 14 Table 8 footnote ††
    The sum of the five lengths in the preceding columns

Only the authors can say what is right here.

Judge's note: Read the All row and all chromosome rows from a 3x render of Table 8. Every chromosome row reconciles with the five-column sum to within rounding (e.g. chr 1: 278.5 vs 279), but the All row gives 3,280.2 against 3,289. The chromosome totals themselves sum to 3,254; adding the NA and UL sequenced bases (5.1 + 9.3) and their gap bases brings this to about 3,280, agreeing with the five-column sum and not with 3,289. No footnote explains an extra 9 Mb. The text conclusion ('about 3,200 Mb' after removing about 100 Mb) is not materially affected. Which figure the authors intended cannot be settled from the PDF.

Substance Text says DNA transposons are "a much larger fraction in fly, mustard weed and worm (25%, 49% and 87%, respectively)"; Table 12 gives worm DNA 5.30% of a 6.50% total, which is 82%.

  • p. 23 Table 12, Worm column
    6.50%

Only the authors can say what is right here.

Judge's note: Read the sentence on PDF page 24 and Table 12 on a zoomed crop of PDF page 23. The same sentence's human 6% (2.8/44.4) and mustard weed 49% (5.1/10.5) reproduce from the Total row, and the neighbouring 75% and 5–25% LINE/SINE figures do too, so the Total row is the denominator. Worm gives 81.5%; rounding of the table entries allows at most 5.35/6.45 = 83%, and the sum of the three listed classes as denominator gives 93%. No denominator in the table gives 87%. Fly is 22.6% against 25%, which is just reachable within rounding (0.75/3.05 = 24.6%). Either the 87% or the worm column is wrong; only the authors can say which.

Substance "a slope of μY:μX = 1.57 corresponding to αm:αf = 2.1" does not follow from the paper's own formula μY:μX = (αm):(αm + 2αf)/3, which gives αm:αf = 2.2 for a slope of 1.57.

  • p. 28 Fast living on chromosome Y
    mY:mX = 1.57 corresponding to am:af = 2.1

Only the authors can say what is right here.

Judge's note: Read the formula, the Page et al. conversion and the sentence on PDF page 28 (the image confirms the '+ 2αf' and '/3'). Solving for the ratio gives α = 2r/(3 − r). For r = 1.57 this is 2.196; any slope that rounds to 1.57 (1.565 to 1.575) gives 2.18 to 2.21, so rounding cannot produce 2.1. A ratio of 2.1 corresponds to a slope of 1.537. The same formula reproduces the quoted Page et al. pair (1.36 gives 1.66, printed 1.7), so the formula is being applied as written. Either the slope or the ratio is slightly off; the conclusion (about twofold, in reasonable agreement with Page et al.) is not affected.

Substance Table 14 gives "43.1" SSR elements per Mb for repeat unit length 2, but the four dinucleotide rows of Table 15 ("SSRs were identified as in Table 14": AC 27.7, AT 19.4, AG 8.2, GC 0.1) sum to 55.4 per Mb.

Judge's note: Read both tables on the page-30 image. Dinucleotide rows of Table 15 sum to 55.4, not 43.1, whereas the ten trinucleotide rows sum to 11.8, exactly the Table 14 value for length 3. The text shares (AC 50%, AT 35%, AG 15%) fit the 55.4 total. Table 15's footnote says the same identification method was used, and I found no statement of a different threshold or counting rule for dinucleotides. Which table is wrong cannot be told from the paper.

Judge's note: Numbers read on the page-39 image. 1,859/544 = 3.42. The chromosome 22 figures in the same paragraph divide correctly (642/245 = 2.6; 145/245 = 59%). No exclusion or different denominator is described for chromosome 19, so one of the three numbers is wrong; which one only the authors can say.

Substance Table 22, Ensembl row, matches to nonhuman proteins: "81,126 (63%)" exceeds the 12,839 predictions in that row; the column total 23,813 and the 63% imply 8,116.

Judge's note: Checked on the page-41 image and a 4x render of the table: the cell is printed "81,126 (63%)" with no footnote marker. The column total minus the other two rows gives 8,116, and 8,116/12,839 = 63.2%, matching the printed percentage. The similar fault in the Total row of the RIKEN column is a separate cell, handled in C058.

Judge's note: Checked on the page-41 image and a 4x render: the cell is printed "219,873 (69%)". The rows above (11,599, 3,016, 7,372) sum to 21,987, and 21,987/31,778 = 69.2%, so the printed figure is a garbled 21,987. A different cell from C057, so not a duplicate.

Judge's note: Read the sentence and Table 22 on the page-41 image. The denominator 31,898 differs from the 31,778 in Table 22 (rows sum to 31,778) and in the Table 23 footnote; the numerator 22,013 differs from the sum of the table's RIKEN column, 21,987. Both pairs give 69%. The text presents Table 22 as the breakdown of these same matches and mentions no other version of the set, so the mismatch is unexplained.

Judge's note: Checked Table 23 on the p43 image (1,695 / 1,036 / 1,018 / 310), the text on p45 and the Fig. 40 bars on p46. The fly (about 1,040), worm (about 1,020) and yeast (about 310) bars agree with the table; only the human bar (about 1,810, read from the axis) does not. The text ratios match the figure, not the table. Both the Table 23 footnote and the Fig. 40 legend say SMART was used; the legend's note about collapsing tandem repeats is not said to differ from the table, and no other explanation was found.

Judge's note: Read Table 23 and its footnote on the p43 image and the 564 figure on p44. The footnote defines the fraction as the percentage of the genome in groups with one member in each of the four species, so each species contributes 564 genes. 564 over the gene count reproduces the three other columns to the printed precision but gives 1.77% for human (1.76% with 32,000). 1.40% would need about 40,300 genes; no such human denominator is stated for this table. Either the percentage or the denominator is wrong; only the authors can say which.

Judge's note: Read Table 13 on a zoomed crop of PDF page 29 and the layout text. The two rows carry the same number but different families, and neither is in an italic related group, so one ID is presumably wrong; which one only the authors can say.

Reference 34 is the growth hormone locus sequence and is used earlier in the paper for early targeted sequencing; its title has nothing to do with the roughly 200-kb chromosome 17 repeats or Smith–Magenis syndrome. The reference list contains no entry mentioning Smith–Magenis (searched the text), so the intended reference is not identifiable from the paper; a different paper by an author named Chen is a likely guess but rests on outside knowledge.

In kb, single bins would hold 1 to 3.7 Gb of aligned sequence, far more than the roughly 835 Mb of finished sequence analysed (of which 3.3% is duplicated, Table 16), so the values can only be bp. The axis unit is wrong; the data are unaffected.

The plotted exon values (about 119 to 134 bp) sit near the median internal exon of Table 21 (122 bp) rather than the mean (145 bp), which suggests the legend is the wrong one, but the intron curve (about 200 to 2,270 bp) does not settle it, so the authors should confirm which statistic was plotted.

The text on p47 says the intermediate filament family has "127 family members", which matches neither name's count in the table (119). Either the ID or the name in the Table 25 row is wrong, and the table may be missing a row (see C069); the files do not settle which.

The other three classes in Figure 17 (13%, 8%, 3%) are the Table 11 values rounded (13.14, 8.29, 2.84); LINEs at 20.42% round to 20%, not 21%. The copy numbers in Figure 17 are all loosely rounded (1,500,000 vs 1,558k; 450,000 vs 443k; 300,000 vs 294k), so the 850,000 vs 868k difference is in keeping with a schematic figure; only the 21% stands out.

Judge's note: Read Table 12 on a zoomed crop of PDF page 23. For human the 0.1-point gap matches the 0.14% 'Unclassified' row of Table 11, so the Total row very probably includes unclassified repeats that Table 12 does not list; that would also cover fly and mustard weed. The table does not say so, and the worm gap (0.8 of 6.5 points) is large. The text on PDF page 24 uses the Total row as denominator (human LINE/SINE 75%, DNA 6%). Family counts are headed 'Approximate' and the small differences there (166 vs 170, 94 vs 90) are not a defect. Downgraded: an unlabelled residual category rather than an arithmetic error.

Wording "chromosome Y shows the lowest density of Alus relative to its GC content, being higher than average for GC content less than 40% and lower than average for GC content over 40%" sits uneasily with "lowest density" and with the next sentence, "Even in AT-rich DNA, Alus are under-represented on chromosome Y".

Judge's note: Read the paragraph on PDF page 26 and a zoomed crop of Figure 26. In the figure the chromosome Y line is the lowest of all chromosomes from the 40–42% bin to the 46–48% bin, which fits 'lower than average for GC content over 40%'. Below 40% the lines are too crowded to tell whether Y is above the average. The next sentence compares Alus with other young repeats on Y, not Y with other chromosomes, so it is not a strict contradiction, but the sentence as written is hard to reconcile with 'lowest density'. The underlying per-chromosome values would settle whether the terms are swapped. Wording ambiguity, not a demonstrated error.

The selenocysteine tRNA is shown as 0 at UCA and is excluded from the 497 (Table 19 lists it separately), so it does not explain the gap; the 48 non-zero anticodons plus SeCys also match the text's "49 anticodons".

A possible cause is that the legend counts aligned RefSeq entries (10,272 mRNAs, more than 92% aligned, 3% alternative splice forms) rather than distinct genes, but neither that nor a different data version is stated, and the legend calls them 'known genes'. Small effect on the figure.

A row appears to be missing, possibly connected to the IPR001664 label problem in C068. Two side points in the cluster are not separate defects worth a correction: "Interpro" in the footnote against "InterPro" elsewhere is a capitalisation slip (real, cosmetic); and "About 60% of families are more numerous in the human than in any of the other four organisms" (p47) against 31 of the 39 table rows is not a clear error, because the sentence can refer to all InterPro families and not only those in the table.

Typo Table 25, C2H2 zinc finger row: InterPro ID printed as "PR000822"; it should be "IPR000822", as in the Fig. 41 and Fig. 44 legends.
  • p. 48 Table 25, C2H2 zinc finger row
    PR000822

Judge's note: The p48 image shows "PR000822" with no leading I, while every other ID in the column begins IPR. The Fig. 41 legend (p46) and Fig. 44 legend (p49) both give C2H2 zinc finger as IPR000822, so the fix is internal to the paper.

Typo Two missing words in one passage: "the observed number of definitive segments is likely be lower than the correct total" (missing "to") and "we estimate that true number of conserved segments is around 190-230" (missing "the").
  • p. 49 Conserved segments between human and mouse
    likely be lower than the correct total
  • p. 49 Conserved segments between human and mouse
    that true number of conserved segments
  • p. 49 Conserved segments between human and mouse, right column
    is likely be lower than the correct total
  • p. 49
    the observed number of de®nitive segments is likely be lower than the correct total

Judge's note: Both read exactly as quoted on the p49 image, right column.

Typo "the current collection now provides then with about 15 SNPs for gene loci of average size": "then" should be "them" (the investigators).
  • p. 52 Recent history from human polymorphism
    now provides then with about 15 SNPs
  • p. 52 Recent history from human polymorphism
    now provides then with about 15 SNPs for gene loci of average size
  • p. 52
    now provides then with about 15 SNPs for gene loci

Judge's note: Read on the page image of PDF p.52 (printed p.911), left column, end of the second paragraph under 'Recent history from human polymorphism'. The printed word is "then"; the sentence only parses with "them".

  • p. 52
    There has been considerably controversy concerning the typical distance

Judge's note: Read on the page image of PDF p.52, right column, linkage disequilibrium paragraph. The adverb is printed before the noun "controversy".

Typo "Finally, it is has not escaped our notice that the more we learn about the human genome, the more there is to explore.": superfluous "is"; should read "it has not escaped our notice".
  • p. 55 Concluding thoughts, final paragraph
    Finally, it is has not escaped our notice
  • p. 55
    Finally, it is has not escaped our notice that the more we learn

Judge's note: Read on the page image of PDF p.55 (printed p.914), right column, last paragraph of 'Concluding thoughts'. Both "is" and "has" are printed.

Typo Reference 2: "De Vries, H. Sur la loie de disjonction des hybrides. Comptes Rendue Hebdemodaires, Acad. Sci. Paris 130, 845–847 (1900)." misspells "loi" as "loie" and "Comptes Rendus Hebdomadaires" as "Comptes Rendue Hebdemodaires".
  • p. 55 Reference 2 (De Vries)
    Sur la loie de disjonction des hybrides. Comptes Rendue Hebdemodaires

Judge's note: Read on the page image of PDF p.55, reference 2. "loie", "Rendue" and "Hebdemodaires" are printed as quoted. These are not French words (loi; Comptes Rendus; hebdomadaires), so the misspellings are evident from the language itself rather than from a bibliographic lookup.

Typo Reference 3: "Berichte der Deutsche Botanische Gesellschaft 18, 232–239. (1900)." has a stray full stop after the page range, unlike every other entry.
  • p. 55 Reference 3
    232–239. (1900).

Judge's note: Read on the page image of PDF p.55, reference 3: the full stop after "232–239" is printed, and references 1, 2, 4 and 5 have none. That part is an evident punctuation slip. The second point ("von Tschermack" for Tschermak) rests on outside knowledge of the author's spelling and cannot be verified from the files; it is left as a query for the authors.

Typo Reference 5 abbreviates the journal as "J Mol Biol 125, 225–246 (1978)" without full stops, whereas reference 6 and later entries print "J. Mol. Biol.".
  • p. 55 Reference 5
    J Mol Biol 125
  • p. 56 Reference 6
    J. Mol. Biol. 162

Judge's note: Read reference 5 on PDF p.55 ("J Mol Biol") and reference 6 on PDF p.56 ("J. Mol. Biol. 162"); reference 47 on p.56 also has the stops. A house-style inconsistency in a single entry, cosmetic only.

Typo Reference 217: "Mazzarella, R. & D. Schlessinger, D. Pathological consequences of sequence duplications in the human genome." prints the second author's initial both before and after the surname; should be "Mazzarella, R. & Schlessinger, D."
  • p. 58 Reference 217
    Mazzarella, R. & D. Schlessinger, D.

Judge's note: Read on the page image of PDF p.58, reference 217. The stray "D." before "Schlessinger" is printed; every other entry uses surname-then-initials.

Typo Acknowledgements read "We thank Compaq Computer Corporations's High Performance Technical Computing Group"; the possessive is malformed and should be "Corporation's".
  • p. 61 Acknowledgements
    Compaq Computer Corporations's High Performance Technical Computing
  • p. 61
    We thank Compaq Computer Corporations's High Performance Technical Computing

Judge's note: Viewed the page 61 image: the acknowledgements print "Compaq Computer Corporations's". The double possessive is a grammatical error whatever the company's name; the same page (affiliation 38) prints "Compaq Computer Corporation".

Typo Reference 451 prints the first author as "Soderland, C., Longden, I. & Mott, R. FPC: a system for building contigs from restriction fingerprinted clones"; the surname is probably "Soderlund".
  • p. 61
    Soderland, C., Longden, I. & Mott, R. FPC: a system for building contigs

Only the authors can say what is right here.

Judge's note: Rests on outside knowledge: the first author of the FPC paper (Comput. Appl. Biosci. 13, 523-535, 1997) is C. Soderlund. The page 61 image prints "Soderland" in reference 451. A text search found no other spelling of this name in the article, so the misspelling cannot be confirmed from the files alone.

Typo Acknowledgements read "P. Green and F. Ouelette for critiques of the submitted version"; the surname is probably "Ouellette".

Only the authors can say what is right here.

Judge's note: Rests on outside knowledge: the person thanked is presumably the bioinformatician F. (Francis) Ouellette, whose surname has a double l. The page 61 image prints "F. Ouelette". The name appears nowhere else in the article, so the files cannot settle the spelling.
