This study observed that numerical chromosomal aberrations were more common in men with severe male factor infertility and azoospermia compared to those with other sperm quality issues, while chromosomal translocations were significantly associated with oligoasthenozoospermia, highlighting important genetic counseling considerations.

The Thr1022Ala variant in the hairless gene is not a disease-causing mutation.

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 study found that the EDAR 1540T/C genetic variant is significantly associated with hair thickness variation in Japanese populations, enhancing previously observed associations in Southeast Asian groups.

In this study, women with the GG polymorphism of the MMP1 gene promoter were found to have a higher likelihood of being diagnosed with polycystic ovary syndrome.

This study analyzed the genetics of the patchiness phenotype in New Zealand rabbits and found that the gene KRT82, with identified SNPs in its promoter, may serve as a potential biomarker for breeding these rabbits.

This study found no significant difference in the prevalence of CYP21A2 mutations between couples with unexplained fertility problems and healthy controls, but identified an association between the c.290-13A/C>G mutation and clinical issues like hormone deviations and polycystic ovary syndrome.

This study identified three variants in the HR gene among Mexican patients with alopecia areata, with one novel variant potentially serving as a risk factor for the disease.

This study suggests that the DNMT3B -579 G>T polymorphism may be a genetic risk factor for colorectal cancer in the Azerbaijani population.

This study suggests that the AGA risk haplotype in Europeans was driven to high frequency by positive selection, likely associated with a variant in the EDA2R gene.

This study found that certain genetic variations in the OPN gene may be linked to atopic dermatitis and a higher prevalence of asthma in Caucasians.

This study found that polymorphisms in KRTAP13.1, KRTAP27-1, and KRTAP24-1 were significantly associated with fiber diameter in Jiangnan cashmere goats, which may aid future breeding and conservation efforts.

This study suggests that polymorphisms in the androgen receptor gene's GGC repeat and the combined CAG-GGC triplet repeats are associated with androgenetic alopecia among Han men in Eastern China.

In this study, the CYP 21A2 gene p.V281L mutation was associated with an increased susceptibility to familial frontal fibrosing alopecia, suggesting an antigen-driven mechanism linked to certain human leukocyte antigen haplotypes.

This study found that IL-18 rs187238 and rs1946518 single nucleotide polymorphisms were associated with increased susceptibility to alopecia areata in a Turkish population.

This report details the case of an 11-year-old girl with APECED syndrome carrying a unique homozygous mutation in the AIRE gene, the first of its kind documented.

This article presents a case study of a 16-year-old male with GAPO syndrome, characterized by growth retardation, alopecia, pseudoanodontia, and optic atrophy, who sought dental treatment for missing teeth.

This study identified a novel homozygous mutation in the 5'-UTR of the POMC gene, suggesting a new molecular mechanism for the syndrome of adrenal insufficiency, obesity, and red hair.

This study identified a new PNPLA1 mutation in a Spanish family with autosomal recessive congenital ichthyosis.

This research found that variations in the KRTAP gene family are likely responsible for the diverse hair phenotypes seen among mammals, influenced by gene repertoire differences, expression, and evolutionary factors.

This study found that variations in the IL16 gene, specifically SNPs rs17875491 and rs11073001, may be associated with increased risk and phenotype expression of alopecia areata in the Korean population.

This study found that an SNP in the FGFR2 gene, rs4752566, was significantly associated with hair thickness in Asian populations, suggesting an effect on hair morphology through altered FGFR2 expression levels.

In this study, specific genetic polymorphisms in the KRT71 gene were associated with hairless and curly phenotypes in Sphynx and Devon Rex cats.

This study reports a novel LSS gene mutation in an Egyptian family with alopecia intellectual disability syndrome 4, expanding the known clinical and genetic features of the condition.

Haplogroup X found in Altaian population supports Amerindian origin.

This study found that certain CYP21A2 mutations significantly reduce enzyme activity, contributing to non-classic congenital adrenal hyperplasia phenotypes, which may aid in enhancing diagnosis and treatment strategies.

In this study, no significant change in androgen receptor gene expression was found in females with recurrent spontaneous abortion, but a mutant genotype may offer some protection against the condition.
