Description:
Performing genetic studies in multiple human populations can identify disease risk alleles that are common in one population but rare in others, with the potential to illuminate pathophysiology, health disparities, and the population genetic origins of disease alleles. Here we analysed 9.2 million single nucleotide polymorphisms (SNPs) in each of 8,214 Mexicans and other Latin Americans: 3,848 with type 2 diabetes and 4,366 non-diabetic controls. In addition to replicating previous findings, we identified a novel locus associated with type 2 diabetes at genome-wide significance spanning the solute carriers SLC16A11 and SLC16A13 (P = 3.9 x 10(-13); odds ratio (OR) = 1.29). The association was stronger in younger, leaner people with type 2 diabetes, and replicated in independent samples (P = 1.1 x 10(-4); OR = 1.20). The risk haplotype carries four amino acid substitutions, all in SLC16A11; it is present at ~50% frequency in Native American samples and ~10% in east Asian, but is rare in European and African samples. Analysis of an archaic genome sequence indicated that the risk haplotype introgressed into modern humans via admixture with Neanderthals. The SLC16A11 messenger RNA is expressed in liver, and V5-tagged SLC16A11 protein localizes to the endoplasmic reticulum. Expression of SLC16A11 in heterologous cells alters lipid metabolism, most notably causing an increase in intracellular triacylglycerol levels. Despite type 2 diabetes having been well studied by genome-wide association studies in other populations, analysis in Mexican and Latin American individuals identified SLC16A11 as a novel candidate gene for type 2 diabetes with a possible role in triacylglycerol metabolism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4127086/" 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/PMC4127086/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉SIGMA Type 2 Diabetes Consortium -- Williams, Amy L -- Jacobs, Suzanne B R -- Moreno-Macias, Hortensia -- Huerta-Chagoya, Alicia -- Churchhouse, Claire -- Marquez-Luna, Carla -- Garcia-Ortiz, Humberto -- Gomez-Vazquez, Maria Jose -- Burtt, Noel P -- Aguilar-Salinas, Carlos A -- Gonzalez-Villalpando, Clicerio -- Florez, Jose C -- Orozco, Lorena -- Haiman, Christopher A -- Tusie-Luna, Teresa -- Altshuler, David -- F32 HG005944/HG/NHGRI NIH HHS/ -- P01 HL045522/HL/NHLBI NIH HHS/ -- P30 AG038072/AG/NIA NIH HHS/ -- R01 CA144034/CA/NCI NIH HHS/ -- R01 CA55069/CA/NCI NIH HHS/ -- R01 CA80205/CA/NCI NIH HHS/ -- R01 DK042273/DK/NIDDK NIH HHS/ -- R01 DK047482/DK/NIDDK NIH HHS/ -- R01 DK057295/DK/NIDDK NIH HHS/ -- R01 HG006399/HG/NHGRI NIH HHS/ -- R01DK053889/DK/NIDDK NIH HHS/ -- R01HL24799/HL/NHLBI NIH HHS/ -- R35 CA53890/CA/NCI NIH HHS/ -- U01DK085526/DK/NIDDK NIH HHS/ -- England -- Nature. 2014 Feb 6;506(7486):97-101. doi: 10.1038/nature12828.
