This study found that the GGC repeat length significantly influenced testosterone levels in oral contraceptive users from high-risk breast cancer families, and homozygosity for short alleles may be linked to increased breast cancer risk.

This study identified differences in adverse symptoms among patients with post-finasteride syndrome based on short and long androgen receptor gene polymorphisms.

This study found that a lower number of GGC sequences in the androgen receptor gene was associated with better clinical response to finasteride in male androgenetic alopecia patients.

This meta-analysis suggests that the G allele of AR StuI polymorphism might be a potential risk factor for AGA, particularly in white populations.

In this study of 131 healthy men aged 30 to 45, no relationship was found between androgen receptor gene polymorphisms related to androgen sensitivity and biological age markers, suggesting that other factors may influence the aging process independently of these genetic variations.

This study found that specific genetic markers near the androgen receptor gene are significantly more common in men with male pattern baldness, suggesting a genetic component in its development.

This article reviews molecular and genetic mechanisms in the development of androgenic alopecia and examines the relationship between androgen receptor gene polymorphism and androgen-dependent diseases, but reports no new clinical results.

This study found no significant difference in the CAG and GGN repeat lengths between infertile and fertile men in Nigeria, but identified a unique GGN allele distribution in the Nigerian population compared to Caucasians.

This review discusses the association between androgen receptor CAG repeat polymorphism and several health conditions, including Kennedy’s disease and urologic disorders, without reporting new clinical results.

This study found that men without prostate cancer carrying the A-allele of SNP rs1204038 had a 65% higher risk of PSA levels above 3 ng/mL compared to those with the G-allele, increasing referrals for further examination.

This study suggests that longer GGN repeat polymorphisms in the androgen receptor gene are associated with polycystic ovary syndrome in women.

This review summarizes how common polymorphisms in androgen and estrogen receptor genes may influence aging-related symptoms and diseases in men, but it reports no new clinical results.

In this study, the researchers reported that finasteride's efficacy in treating female pattern hair loss in Japanese patients was not predictable based on CAG repeat numbers in the androgen receptor gene.

This thesis explores both environmental and genetic factors in prostate cancer, focusing on surrogate hormone markers, medical radiation, family history, and genetic polymorphisms related to DNA repair and hormone marker genes, but reports no new clinical findings.

In this study, researchers observed that male COVID-19 patients with more than 23 CAG repeats in the androgen receptor gene and lower testosterone levels experienced more severe disease outcomes.

This review examines genetic variation in the ovine KRTAP1.1 gene and its potential impact on wool quality, reporting no new findings but suggesting opportunities for developing gene markers for wool and pelt traits.

This study, conducted among Egyptians, found a borderline significant association between the Stul polymorphism of the androgen receptor gene and androgenetic alopecia in males, with higher androgen receptor expression in balding scalp areas.

This study found that the less common CAG-rs4045402 and GGN-rs3138869 polymorphisms were more frequent in patients with post-finasteride syndrome and androgenetic alopecia, suggesting a genetic predisposition to AGA development.

This study found that African American men with prostate cancer have higher rates of somatic and germline androgen receptor mutations than Caucasian American men, which may contribute to ethnic differences in disease progression and outcomes.

This study found that the AR-E211 A allele is associated with a lower risk of both metastatic prostate cancer and androgenetic alopecia in an Australian population.

In this study, researchers found that while the SNP rs6152 is strongly associated with androgenetic alopecia, the GGN triplet repeat is not, suggesting the causative variant is likely a non-coding one.

This study found that serum androgen levels in premenopausal women may be influenced by genetic variants of the androgen receptor and estrogen receptor β genes.

In this study, researchers found that androgen receptor gene polymorphism is associated with higher androgenetic alopecia grades and PSA levels in men with benign prostatic hyperplasia, but not with prostate cancer.

This study reported no significant association between vaspin and visfatin -4689G/T gene polymorphisms and alopecia areata in the Turkish population, although the visfatin GT genotype may pose a risk factor for the condition.

This study found that mutations in certain keratin genes significantly affect wool traits in Chinese Merino sheep, suggesting these genes could be important for sheep breeding to improve wool quality.

Hormones and genetics play key roles in male and female baldness, which can affect mental health and may be linked to other health issues.

This review discusses the molecular mechanisms of androgens and androgen receptors in skin disorders, particularly androgenetic alopecia, and reports no new clinical results; it highlights potential areas for future treatment development.

This review discusses characteristics of androgenetic alopecia in Asian patients and includes algorithmic management guidelines, but reports no new clinical findings.

In this study, Egyptian nodulocystic acne patients had significantly fewer CAG repeats in their androgen receptor gene compared to controls, which may influence acne development and suggest a role for antiandrogen therapy in treatment strategies.

This study found an association between 'short' CAG repeats in the androgen receptor gene and increased non-random X chromosome inactivation in women with androgenic alopecia.
