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 no difference in CAG repeat length between Chinese and Australian men, refuting the hypothesis that this polymorphism and central prostate zone volume are markers of long-term androgen sensitivity.

This review discusses the roles of androgens and androgen receptor in skin diseases like acne and hirsutism, and highlights the promise of antiandrogen drugs, reporting no new clinical findings.

This article summarizes the main plenary sessions of the 88th Annual Meeting of the British Association of Dermatologists and reports no new clinical findings.

This study found that, among fertile egg donors, the AR gene CAG polymorphism was associated with differences in antral follicle count but did not impact ovarian response to gonadotrophins.

This review summarizes the influence of gene polymorphisms on genetic predisposition to polycystic ovary syndrome, but reports no new experimental or clinical results.

This study found that girls with polycystic ovary syndrome and longer SHBG and AR gene repeats experienced greater improvements in lipid and androgen levels after one year of metformin treatment.

This chapter reviews the role of androgen receptors in mediating the actions of androgens in specific tissues and provides no new experimental findings.

This study found that in women with polycystic ovary syndrome, shorter CAG repeat lengths in the androgen receptor gene were associated with lower dihydrotestosterone and androstenedione levels, but a higher prevalence of acne and hirsutism.

This study did not find any correlation or linkage disequilibrium between androgen receptor gene CAG/GGC haplotypes and androgenetic alopecia in Mexican brothers.

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.

Finger length ratios are not linked to the number of specific gene repeats affecting testosterone sensitivity.

This study investigated a patient with spinal and bulbar muscular atrophy who had 68 CAG repeats, revealing early onset and unique symptoms not previously documented in the condition.

In this study, researchers found no significant association between VDR gene polymorphisms and the susceptibility to alopecia areata, suggesting that these genetic variations may not play a role in the disease's development.

This study found that SNPs in the MVK, ARPC1B, and CA2 genes may indicate a genetic predisposition for severe acne related to steroidogenesis.

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 Han Chinese women carrying the rs6152A allele had a significantly higher risk of developing polycystic ovary syndrome compared to those with the rs6152GG genotype.

This study reported a significant association between the SNP rs2479106 in the DENND1A gene and PCOS in Saudi Arabian females, while no association was found for SNPs rs10818854 and rs10986105.

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 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 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.

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 rs2228570 polymorphism of the VDR gene was associated with an increased risk of melanoma, while the rs731236 polymorphism was linked to a protective effect against the disease in Colombian patients.

Certain genetic differences may affect how likely someone is to get COVID-19 and how severe it might be.

This study found no association between the -866G/A polymorphism in the UCP2 gene and the development of polycystic ovary syndrome.

Certain gene variations are significantly linked to hair loss, especially in white people.

In this study, researchers found that shorter CA repeats in the ERbeta gene are correlated with PSA expression, and PSA immunoexpression is associated with increased disease-free survival in breast cancer.

Acne is a common skin condition linked to diet, hormones, and genetics, and early treatment can prevent scarring.

This review discusses the potential link between androgenic alopecia, androgens, and the severity of COVID-19, highlighting possible therapeutic targets but reports no new clinical results.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.
