title: A functional variant of IRS1 is associated with type 1 diabetes in families from the US and UK.
abstract: A collection of 767 multiplex type 1 diabetes families from the US and UK were tested for linkage to the IRS1 gene and for allelic association with a specific variant of IRS1, G972R. Pedigree disequilibrium testing revealed preferential transmission of the 972R allele to affected offspring in these families (P = 0.02). Linkage analyses conditioning on status at IRS1 position 972 suggest the possibility of interaction with an unidentified locus on chromosome 8.
