The enzyme PA-PLA1α is important for proper hair follicle development.

This review discusses the genetic origins of autosomal recessive woolly hair with hypotrichosis and reports no clinical results; it highlights the link to homozygous variants in the K25 keratin gene.

This study found that overexpression of sPLA2-X in mice was associated with alopecia and hair follicle abnormalities, highlighting its potential role in hair follicle homeostasis.

This case series describes eight instances of autosomal recessive woolly hair in an Indian population over the past 12 years, detailing their clinical presentation, hair traits, and treatment response.

Proteomic analysis can identify genetic differences in mouse hair, helping understand hair defects and variations.

This study found that mice lacking sPLA2-IIE had distinct skin abnormalities, particularly affecting hair follicles, highlighting the differing roles of sPLA2 isoforms in mouse skin.

This study identified specific genetic variants as the cause of visual impairment and non-syndromic alopecia in two brothers, reinforcing the link between PDE6H variants and achromatopsia and LPAR6 variants and alopecia.

This review discusses selection signatures and selective sweeps in fiber-producing animals and recommends further genomic investigations to identify genes related to important fiber traits, without providing new results.

In this study, researchers sequenced the KRT71 gene in 102 dromedary camels to find genetic polymorphisms linked to hair shape, identifying 17 variants but none that fully explained hair shape variations, suggesting other genes may also play a role.

This review discusses the diagnostic and therapeutic challenges of hair shaft disorders and suggests diagnostic tools like trichoscopy and light microscopy, but reports no new clinical results.
