Hypotrichosis is a condition of abnormal hair pattern characterized by sparse to absent hair on different parts of the body, including the scalp. The condition is often characterized by tightly curled woolly hairs, discoloration of hair, and development of multiple keratin filled cysts or papules on the body. Sequence analysis of the lipase H (LIPH) gene, mapped on chromosome 3q27.3, led to the identification of a novel frameshift deletion variant (c.932delC, p.Pro311Leufs*3) in one family and previously reported 2-bp deletion (c.659_660delTA) in five other families, inherited hypotrichosis, and woolly hair in an autosomal recessive pattern. The study further extends the body of evidence that sequence variants in the LIPH gene result in hypotrichosis and woolly hair phenotype.
