androgen receptor gene polymorphisms androgenetic alopecia AGA G allele AR Stul polymorphism CAG triplet-repeat polymorphism GGC triplet-repeat polymorphism androgen receptor genetic variations male pattern baldness

TLDR G allele of AR Stul polymorphism linked to higher hair loss risk, especially in white people.

This meta-analysis examined the association between androgen receptor gene polymorphisms and androgenetic alopecia (AGA). The study found that the G allele of the AR Stul polymorphism may be a potential risk factor for AGA, especially in white populations. However, the CAG and GGC triplet-repeat polymorphisms of the AR gene did not have any obvious association with risk for AGA. The study suggests that further large studies with adequate methodological quality are necessary to obtain valid results.

research Androgenic Alopecia: Cross-Talk Between Cell Signal Transduction Pathways

1 citations , May 2017 in “InTech eBooks”

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
