Evaluation of NLRP1 gene polymorphisms in Vogt-Koyanagi-Harada disease.

Purpose: Polymorphisms of the NACHT [neuronal apoptosis inhibitory protein (NAIP), CIITA, HET-E, TP1] and leucine-rich repeat protein 1 (NLRP1) gene are reported to be associated with susceptibility to vitiligo and several autoimmune diseases. Vogt-Koyanagi-Harada (VKH) disease is an autoimmune disorder affecting melanocytes in the skin, eyes, inner ear, and meninges. In this study, genetic associations between VKH disease and single-nucleotide polymorphisms (SNPs) surrounding the NLRP1 gene were investigated.

Evaluation of PTPN22 polymorphisms and Vogt-Koyanagi-Harada disease in Japanese patients.

Purpose: Vogt-Koyanagi-Harada (VKH) disease is an autoimmune disorder against melanocytes. Polymorphisms of the protein tyrosine phosphatase non-receptor 22 gene (PTPN22) have recently been reported to be associated with susceptibility to several autoimmune diseases. In this study, genetic susceptibility to VKH disease was investigated by screening for single nucleotide polymorphisms (SNPs) of PTPN22.
