Background

Autosomal recessive hypotrichosis is a rare genetic irreversible hair loss characterized by sparse scalp hair, sparse to absent eyebrows and eyelashes, and sparse axillary and body hair. Affected male individuals have normal beard hair.

Objectives

To search for pathogenic mutations in the human P2RY5 gene in Pakistani families with autosomal recessive hereditary hypotrichosis.

Methods

In the present report, 16 unrelated consanguineous Pakistani families having multiple affected individuals with autosomal recessive hypotrichosis were investigated. Linkage in these families was searched by genotyping microsatellite markers linked to autosomal recessive hypotrichosis loci LAH1, LAH2 and LAH3. Thirteen of the families showed linkage to the LAH3 locus on chromosome 13q14.11-q21.32. These families were then subjected to direct sequencing of the P2RY5 gene, which encodes a G protein-coupled receptor.

Results

Sequence analysis of the P2RY5 gene revealed two novel missense mutations (c.742A>T; p.N248Y and c.830C>T; p.L277P) in three families. Five previously described mutations including three missense (c.188A>T; p.D63V, c.436G>A; p.G146R, c.562A>T; p.I188F), one insertion (c.69insCATG; p.24insHfsX52) and one complex deletion (c.172-175delAACT; 177delG; p.N58-L59delinsCfsX88) were detected in the other 10 families.

Conclusions

Mutations revealed in the present study extend the body of evidence implicating the P2RY5 gene in the pathogenesis of human hereditary hair loss."xsd:string
