Description:
As a first step toward understanding how rare variants contribute to risk for complex diseases, we sequenced 15,585 human protein-coding genes to an average median depth of 111x in 2440 individuals of European (n = 1351) and African (n = 1088) ancestry. We identified over 500,000 single-nucleotide variants (SNVs), the majority of which were rare (86% with a minor allele frequency less than 0.5%), previously unknown (82%), and population-specific (82%). On average, 2.3% of the 13,595 SNVs each person carried were predicted to affect protein function of ~313 genes per genome, and ~95.7% of SNVs predicted to be functionally important were rare. This excess of rare functional variants is due to the combined effects of explosive, recent accelerated population growth and weak purifying selection. Furthermore, we show that large sample sizes will be required to associate rare variants with complex traits.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3708544/" 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/PMC3708544/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tennessen, Jacob A -- Bigham, Abigail W -- O'Connor, Timothy D -- Fu, Wenqing -- Kenny, Eimear E -- Gravel, Simon -- McGee, Sean -- Do, Ron -- Liu, Xiaoming -- Jun, Goo -- Kang, Hyun Min -- Jordan, Daniel -- Leal, Suzanne M -- Gabriel, Stacey -- Rieder, Mark J -- Abecasis, Goncalo -- Altshuler, David -- Nickerson, Deborah A -- Boerwinkle, Eric -- Sunyaev, Shamil -- Bustamante, Carlos D -- Bamshad, Michael J -- Akey, Joshua M -- Broad GO -- Seattle GO -- NHLBI Exome Sequencing Project -- R01 HG003229/HG/NHGRI NIH HHS/ -- RC2 HL-102923/HL/NHLBI NIH HHS/ -- RC2 HL-102924/HL/NHLBI NIH HHS/ -- RC2 HL-102925/HL/NHLBI NIH HHS/ -- RC2 HL-102926/HL/NHLBI NIH HHS/ -- RC2 HL-103010/HL/NHLBI NIH HHS/ -- RC2 HL102926/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2012 Jul 6;337(6090):64-9. doi: 10.1126/science.1219240.
