Abstract

Mutations generate sequence diversity and provide a substrate for selection. The rate of de novo mutations is therefore of major importance to evolution. Here we conduct a study of genome-wide mutation rates by sequencing the entire genomes of 78 Icelandic parent-offspring trios at high coverage. We show that in our samples, with an average father's age of 29.7, the average de novo mutation rate is 1.20 × 10(-8) per nucleotide per generation. Most notably, the diversity in mutation rate of single nucleotide polymorphisms is dominated by the age of the father at conception of the child. The effect is an increase of about two mutations per year. An exponential model estimates paternal mutations doubling every 16.5 years. After accounting for random Poisson variation, father's age is estimated to explain nearly all of the remaining variation in the de novo mutation counts. These observations shed light on the importance of the father's age on the risk of diseases such as schizophrenia and autism.

  • The observed SNP heritability for autistic carriers reflects autism rather than factors associated with the generation of germline mutations.

    “suggesting that the observed SNP heritability for autistic carriers reflects autism rather than factors associated with the generation of germline mutations57,58.”

  • Advanced paternal age correlates with increased rates of germline mutation in offspring.

    “We and others have demonstrated that advanced paternal age correlates with increased rates of germline mutation in offspring28–30”
  • ASD is often caused by newly arising CNVs or rare germline mutations, particularly in sperm of older fathers.

    “ASD is often due to newly arising gene copy number variants (CNVs) — such as a deletion or duplication of a region of a chromosome — or a rare mutation that arises in the germ cell, particularly in sperm of older fathers5–10.”
  • De novo mutations arising in the germline are a significant cause of ASD.

    “Recent evidence suggests that de novo mutations that arise in the germline are a significant cause of ASD, although it is important to keep in mind that the genetic aetiology of about 70% of the forms of ASD is unknown and it remains perplexing why ASD is at least four times more prevalent in males than in females.”
  • References 7-10 used exome and whole-genome sequencing to show the importance of rare mutations in ASD and to identify new genetic mutations linked to ASD.

    “References 7– 10 use exome and entire genome sequencing to demonstrate the importance of rare mutations in ASD and identify new genetic mutations associated with ASD.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
