Title: Linkage of the VNTR/insulin-gene and type I diabetes mellitus: increased gene sharing in affected sibling pairs. Author: Owerbach D, Gabbay KH. Journal: Am J Hum Genet; 1994 May; 54(5):909-12. PubMed ID: 7909987. Abstract: Ninety-six multiplex type I diabetic families were typed at the 5' flanking region of the insulin gene by using a PCR assay that better resolves the VNTR into multiple alleles. Affected sibling pairs shared 2, 1, and 0 VNTR alleles--identical by descent--at a frequency of .47, .45, and .08, respectively, a ratio that deviated from the expected 1:2:1 ratio (P < .001). These results confirm linkage of the chromosome 11p15.5 region with type I diabetes mellitus susceptibility.[Abstract] [Full Text] [Related] [New Search]
