NLRP1 and autoimmune disease: Predisposition to vitiligo and its associated autoimmune diseases may be related to single nucleotide polymorphisms (SNPs) of genes, such as rs12150220, rs2670660, rs6502867, and rs8182352 of the NLRP1 gene on chromosome 17p13.2, which is also named NALP1 (NACHT, LRR, and PYD Domains-Containing Protein 1) [8–12].
