A genomewide screen for generalized vitiligo: confirmation of AIS1 on chromosome 1p31 and evidence for additional susceptibility loci.

ABSTRACT: Generalized vitiligo is a common autoimmune disorder characterized by the development of white patches of skin and overlying hair due to loss of pigment-forming melanocytes from the involved areas. Family clustering of cases is not uncommon, in a pattern suggestive of multifactorial, polygenic inheritance, and there is strong association between vitiligo and other autoimmune diseases. To map genetic loci that confer susceptibility to generalized vitiligo and perhaps other autoimmune diseases, we performed a genomewide linkage scan in 71 white multiplex families with vitiligo from North America and the United Kingdom. Linkage was assessed by multipoint nonparametric linkage analyses. One linkage signal, AIS1, located at 1p31, met genomewide criteria for highly significant linkage (nonparame
