This study found that mutations in the FGF5 gene are the primary genetic factor causing long hair in domestic cats through an autosomal recessive mechanism.

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 genetic study identified four new keratin-associated protein genes in sheep, revealing significant sequence variation and suggesting complex evolutionary dynamics, with unique variants in some sheep breeds linking them to Romanov sheep ancestry.

This study highlights that ZNF750, a zinc-finger transcription factor, is crucial for epidermal differentiation and barrier formation in skin by activating genes involved in lipid processing and stratum corneum development, and links ZNF750 sequence variations to skin inflammatory diseases like psoriasis.

This study found that variation in the ovine KRTAP27-1 gene may influence wool growth, with certain genotypes associated with higher mean staple length and greasy fleece weight in sheep.

This study identified novel mitochondrial DNA variations in PCOS patients from Pakistan, which may serve as genetic predisposition markers, highlighting especially the potential pathogenicity of frameshift mutations in the MT-ND2 gene.
