A/APublished research associates this genotype with lower androgen receptor gene activity — associated with a lower population-level likelihood of early androgenetic alopecia (male pattern baldness) in men.
A/GIntermediate — one copy of each allele.
G/GPublished research associates this genotype with higher androgen receptor gene activity — associated with a higher population-level likelihood of early androgenetic alopecia (male pattern baldness) in men. This is one of many genes that contribute; family history and other genes matter too.
