Abstract

Androgenetic alopecia, or male pattern baldness, is a complex condition with a strong heritable component. In 2001, we published the first significant evidence of a genetic association between baldness and a synonymous coding SNP (rs6152) in the androgen receptor gene, AR. Recently, this finding was replicated in three independent studies, confirming an important role for AR in the baldness phenotype. In one such replication study, it was claimed that the causative variant underlying the association was likely to be the polyglycine (GGN) repeat polymorphism, one of two apparently functional triplet repeat polymorphisms located in the exon 1 transactivating domain of the gene. Here, we extend..
