The insulin minisatellite

The insulin minisatellite has been associated with predisposition to type 1 diabetes, type 2 diabetes, polycystic ovarian syndrome, obesity, and infant birth size (OMIM 125852).

We analysed variant repeat distribution in 876 alleles of the insulin minisatellite from the parents of 219 families of type 1 diabetes affected sib pair families, and defined 189 different alleles within this cohort.

In addition, de novo mutant alleles generated both in the germline and soma were isolated by size-enrichment small pool PCR, and their structures characterised.

The sequences of variant repeats, and nomenclature of allele and mutants codes, is described here:
