TLDR Mutations in the P2RY5 gene cause autosomal recessive woolly hair.
Researchers identified that mutations in the P2RY5 gene, which encodes a G protein–coupled receptor, were responsible for autosomal recessive woolly hair (ARWH) in six Pakistani families. Genetic linkage analysis showed a strong association with chromosome 13q14.2–14.3. P2RY5 is expressed in the inner root sheath of hair follicles, and its disruption was found to underlie ARWH, revealing a new gene involved in determining human hair texture.
