Description:
Patterns of amino acid conservation have served as a tool for understanding protein evolution. The same principles have also found broad application in human genomics, driven by the need to interpret the pathogenic potential of variants in patients. Here we performed a systematic comparative genomics analysis of human disease-causing missense variants. We found that an appreciable fraction of disease-causing alleles are fixed in the genomes of other species, suggesting a role for genomic context. We developed a model of genetic interactions that predicts most of these to be simple pairwise compensations. Functional testing of this model on two known human disease genes revealed discrete cis amino acid residues that, although benign on their own, could rescue the human mutations in vivo. This approach was also applied to ab initio gene discovery to support the identification of a de novo disease driver in BTG2 that is subject to protective cis-modification in more than 50 species. Finally, on the basis of our data and models, we developed a computational tool to predict candidate residues subject to compensation. Taken together, our data highlight the importance of cis-genomic context as a contributor to protein evolution; they provide an insight into the complexity of allele effect on phenotype; and they are likely to assist methods for predicting allele pathogenicity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4537371/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4537371/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jordan, Daniel M -- Frangakis, Stephan G -- Golzio, Christelle -- Cassa, Christopher A -- Kurtzberg, Joanne -- Task Force for Neonatal Genomics -- Davis, Erica E -- Sunyaev, Shamil R -- Katsanis, Nicholas -- R01 DK072301/DK/NIDDK NIH HHS/ -- R01 DK075972/DK/NIDDK NIH HHS/ -- R01 DK095721/DK/NIDDK NIH HHS/ -- R01 EY021872/EY/NEI NIH HHS/ -- R01 GM078598/GM/NIGMS NIH HHS/ -- R01 HD042601/HD/NICHD NIH HHS/ -- R01 MH101244/MH/NIMH NIH HHS/ -- R01DK072301/DK/NIDDK NIH HHS/ -- R01DK075972/DK/NIDDK NIH HHS/ -- R01EY021872/EY/NEI NIH HHS/ -- R01HD04260/HD/NICHD NIH HHS/ -- U01 HG006500/HG/NHGRI NIH HHS/ -- England -- Nature. 2015 Aug 13;524(7564):225-9. doi: 10.1038/nature14497.
