Hsueh A Genome-Wide Linkage Scan of Insulin Level Derived Traits: The Amish Family Diabetes Study 2007.0 6 .pdf application/pdf 5153 427 62 RESEARCH DESIGN AND METHODS—We conducted a series of genetic analyses, including genome-wide and fine-mapping linkage studies, based on insulin levels measured during an oral glucose tolerance test (OGTT) in 552 nondiabetic participants in the Amish Family Diabetes Study. Fine-mapping study further refined our signal for insulin 30 on chromosome 15 (LOD 2.38 at 68 cM). CONCLUSIONS—These results suggest that there may be different genes influencing variation in OGTT measures of insulin Several studies have investigated the genetic epidemiology of fasting insulin levels and OGTT-derived indices traits may share common genetic influence, and performed genome-wide and fine-mapping linkage analyses of genetic influences underlying these OGTT-derived measures of insulin secretion and resistance. genome scan provides evidence of linkage on chromosomes 2p and 15q to measures of insulin secretion. genetic correlations were observed between fasting insulin and HOMA-IR, suggesting that these two measures LOD scores �1.18 (P � 0.01) for each insulin-related trait from multipoint linkage analyses ./cache/work_ghjwb3wrkrfr3ddzqf3qytyeri.pdf ./txt/work_ghjwb3wrkrfr3ddzqf3qytyeri.txt
