The document explains the genetic causes and characteristics of inherited hair disorders.

Male pattern baldness is largely genetic, linked to the androgen receptor gene, and may relate to certain health issues.

This review describes the diagnosis and management challenges of telogen effluvium, a type of hair loss triggered by physiological stress, and summarizes current understanding of its mechanisms and treatments while recommending future research directions.

This review found that while elevated DHEA levels are observed in some women with PCOS, especially those with hyperandrogenism, inconsistencies across studies suggest that standardized measurement and analyses are needed to clarify DHEA's role as a biomarker and factor in PCOS pathophysiology.

This study describes androgenetic alopecia as a common non-scarring hair loss condition primarily influenced by genetic factors and androgen sensitivity, notably impacting psychosocial well-being, especially in females and younger males seeking treatment.

This article discusses therapeutic options for androgenetic alopecia, emphasizing the importance of aligning treatments with patient preferences, but it reports no new clinical findings.

This case report describes a patient with mutations in both alleles of the vitamin D receptor who exhibited hair loss clinically indistinguishable from generalized atrichia with papules, suggesting a potential genetic pathway shared with the hairless gene.

This review found that current forensic DNA phenotyping panels for biogeographical ancestry and visible traits face significant limitations due to inconsistencies in terminology, genetic understanding, and genotyping technologies, highlighting the need for harmonization and further research.

In this study, researchers found that size polymorphisms in certain hKAP1 genes are linked to the hKAP1.1B and hKAP1.3 genes, arising from intragenic deletions and duplications in Japanese and Caucasian populations.

This study examined 4-azasteroids using 13C-NMR spectroscopy, detailing the NMR spectrum assignments and reporting a new molecular complex of finasteride with dioxane.

This review examines the process of cornification as a mode of programmed cell death and outlines how keratinocytes activate anti-cell death mechanisms to maintain epidermal homeostasis, but reports no new results.

This case report highlights the importance of early mycological diagnostics, supported by dermoscopy and ultraviolet-enhanced fluorescence dermoscopy, in preventing scarring from kerion celsi-associated hair loss in children.

This study identified eight alleles of the caprine KAP13-3 gene in cashmere goats, which could influence gene expression and cashmere fiber characteristics.

This study suggests that congenital atrichia with papular lesions may be more common than previously thought and proposes diagnostic criteria including the observation of hypopigmented whitish streaks on the scalp.

This study identifies a mutation in the hairless gene that may impact thyroid receptor interaction, contributing to alopecia universalis congenita in an Arab Israeli patient.

In this review, researchers reported that pyroptosis, a type of inflammatory cell death linked to inflammasome activity, is a key factor in the pathogenesis of alopecia areata and may present new therapeutic opportunities, though most treatments are still in early research stages.

This study found that vitamin D, vitamin B12, and iron deficiencies, along with thyroid dysfunction, may be associated with telogen effluvium.

This review discusses advances in molecular biology and genetics related to androgenetic alopecia and reports no new clinical results.

This study identified mutations in the SNRPE gene that may disrupt hair growth, linking a spliceosome component to hereditary hair loss disorders.

In this study, KRTAP28-1 variants were associated with wool fibre diameter in sheep, suggesting potential as a gene marker for reducing fibre diameter.

This study reports that some human cell surface HLA-I molecules (including HLA-B27) can appear without their usual peptide component, potentially altering immune interactions, influencing arthritis development in specific mice models, and exhibiting upregulation in certain cancer cells.

In this genetic study, the researchers found that variants in the CLEC4D gene are significantly associated with the development of alopecia areata among individuals in the Jordanian population, pointing to a potential genetic influence on the disease's pathogenesis.

A specific gene mutation causes woolly hair and hair loss.

This review discusses advancements and gaps in using proteomics for hair testing and its potential in developing a medical proteome repository, but reports no new research findings.

This study found that CRP levels were elevated in alopecia areata patients, with an inverse linear association between serum vitamin D and CRP levels specifically noted in ophiasis AA.

In this in silico study, researchers analyzed nonsynonymous SNPs in the LIPH gene linked to hypotrichosis and identified three potentially harmful variants (W108R, C246S, and H248N) out of 215 total, using sequence- and architecture-based bioinformatics techniques to differentiate between harmful and benign SNPs.

In this study, significant associations were observed between specific genetic polymorphisms in BDNF and CRH-R1 and the occurrence of vitiligo, along with differing serum levels of neurotransmitters between vitiligo patients and healthy controls.

Olmsted syndrome can be inherited as an autosomal recessive trait due to a rare TRPV3 gene mutation.

In this study, researchers found that the rs3118470 mutation in the IL2RA gene significantly increases the risk of developing alopecia areata, and they emphasize the need for future research with larger, more diverse populations to validate these results.

This literature review observed that patients with thrombophilic conditions may experience distinct and more severe Long COVID symptoms, potentially linked to chronic hypercoagulation post-COVID-19 infection.
