Mutation: Difference between revisions

|}

Some evidence suggests that there are more mutants with deleterious mutations in the human population due to a number of factors, including but not limited to: milder ecological conditions, modern medicine, smaller family sizes<ref>https://www.ncbi.nlm.nih.gov/pubmed/9371795/</ref>, advanced paternal age<ref>https://www.spectrumnews.org/news/parental-age-different-impact-autism-schizophrenia/</ref> and especially due to much lower infant mortality.<ref>https://doi.org10.1007/s40806-017-0084-x</ref>

Given the complex nature and function of the human brain, one would expect it to be particularly vulnerable to deleterious mutations,<ref>https://www.ncbi.nlm.nih.gov/pubmed/23153596/</ref> which may be reflected in the apparent rise in the prevalence of Autism Spectrum Disorders, as it has been argued that up to 30% of cases of this condition in simplex families (where only one member has the condition) could be attributed to ''de novo'' mutations.<ref>https://www.ncbi.nlm.nih.gov/pubmed/26401017/</ref>
