Lack of Association between PTPN22 Gene +1858 C>T Polymorphism and Susceptibility to Generalized Vitiligo in a Turkish Population.


ABSTRACT: BACKGROUND:Vitiligo is an autoimmune polygenic disorder characterized by loss of pigmentation due to melanocyte destruction. The PTPN22 gene +1858 C>T single nucleotide polymorphism (rs2476601) has been shown to be associated with various autoimmune disorders. OBJECTIVE:The aim of this study was to investigate whether the PTPN22 gene +1858 C>T single nucleotide polymorphism is associated with susceptibility to generalized vitiligo in a Turkish population. METHODS:One hundred and seven patients with generalized vitiligo, and one hundred and twelve gender-, age-, and ethnic-matched controls were enrolled in the study. Genotyping was done by polymerase chain reaction-restriction fragment length polymorphism. RESULTS:The PTPN22 +1858 C>T genotype and allele frequencies of the generalized vitiligo patients did not differ significantly from those of healthy controls. CONCLUSION:We found no association between the PTPN22 +1858 C>T gene polymorphism and vitiligo susceptibility in Turkish generalized-vitiligo patients.
