This study identified an association between alopecia areata and the MICA*009 and HLA-B14 genetic markers, highlighting the importance of studying them together to better understand their role in this condition.

This study reports that using laser microdissection to isolate telogen hair follicles significantly improves DNA extraction efficiency for STR typing, reducing contamination from keratin.

This study found that eyebrow follicles, as opposed to buccal swabs or nails, are the most reliable tissue for post-HSCT germline genetic testing due to lower donor DNA contamination.

The study found that sonication washing of hair roots with fewer than 50 visible nuclei could reduce the number of nuclei available for DNA extraction and STR typing, suggesting that for laboratories focused on nuDNA analysis, a gentler washing method might be adequate.

This paper discusses forensic DNA phenotyping, emphasizing its ability to infer visible traits from biological samples without reference samples, but notes ethical and legal concerns related to its use.

This review discusses advances in forensic DNA profiling, highlighting new genetic markers and methods for identifying unknown individuals, but reports no new research findings.

This study found that certain Y-chromosome alleles may influence susceptibility to prostate cancer among Iraqi males, suggesting potential genetic screening markers for the disease.

This study found that specific Y-chromosome alleles may influence susceptibility to prostate cancer in Iraqi males, suggesting their potential use in screening for the disease.

This review highlights the evolution of forensic genetics from basic DNA analysis to complex genome-wide studies, enabling insights into personal traits, ancestry, and habits, and suggests future advancements through technologies like CRISPR and AI.

This study found that certain tandem repeats predict darker hair color across diverse ancestry groups and can contribute to a polygenic score for hair color, independent of SNP variation.

This study reports that hair analysis could potentially monitor metformin use in diabetic patients, suggesting a possible correlation between daily dose and concentration in dark hair but not in light hair.

Repetin is a protein involved in skin and hair development, binding calcium and compensating for other proteins when needed.

This study identified a novel keratin-associated protein, KAP24.1, which is specifically expressed in the human scalp and located in the hair cuticle.

This study found no significant difference in CAG repeat numbers of the androgen receptor gene between Han Chinese women with female pattern hair loss and healthy controls, suggesting it may not be a genetic marker for FPHL in this population.

This research reports that the polyG fragment within the Hoxc13 protein alters its gene regulatory functions, which could have influenced mammalian hair evolution by affecting pathways related to hair follicle development.

This review discusses the potential role of androgen receptor CAG repeat polymorphism testing in hypogonadism management for both sexes, but its clinical utility remains unclear and requires further investigation.

This study validated a highly selective and fast LC–MS/MS method for accurately measuring levels of tadalafil and finasteride in human plasma, adhering to international bioanalytical guidelines.

This study developed and validated a liquid chromatography-mass spectrometry method for accurately identifying and quantifying tamsulosin and finasteride in pharmaceutical forms, showing its effectiveness for quality control.

This study described four adult male cases of Kennedy disease with typical neurological symptoms and noted gynecomastia as the most frequent endocrinological manifestation, accompanied by an abnormal expansion in the androgen receptor gene.

This article discusses Kennedy's disease, detailing its genetic cause, symptoms, and diagnostic criteria, but reports no new clinical findings and highlights a lack of causal therapy.

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.

This study reported that a subcutaneous injection formulation using PLGA microspheres to release finasteride stably achieved sustained monthly drug delivery without burst release in beagle dogs, with a dose of 16.8 mg identified as optimal for potential first-in-human trials.

This case report describes a girl with Denys-Drash syndrome misdiagnosed with hyperandrogenism due to biotin interference in immunoassays, highlighting the need for awareness of laboratory result discrepancies.

The researchers reported that the novel MBTPS2 variant p.Glu172Asp found in a male proband is likely pathogenic, consistent with osteogenesis imperfecta symptoms and molecular signatures, including disrupted fatty acid metabolism and collagen production.

This study found that isolated human scalp hair follicles express PGE2 genes and EP2 protein, suggesting PGE2 may play a crucial role in regulating hair growth.

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 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.

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 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 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.
