Overlapping and Distinct Gene Polymorphisms in Alopecia Areata in an Iranian Population.

Alopecia areata (AA) is considered to have a multifactorial etiology and polymorphisms in certain genes have been shown to be associated with AA. Although several reports have investigated the effect of (FASLG) gene variations with predisposing to AA, genetic association of disease, however, varies among different ethnicities and no data have so far been reported in Iranian population. The present study aimed to uncover a possible association between variations in genes and AA.
