Hereditary hypotrichosis is a heterogeneous group of inherited hair loss disorders characterized by diffused or localized thinning or absence of hair affecting scalp, eyebrows and eyelashes, and other body parts. Over the past few years, at least four autosomal dominant and six autosomal recessive forms of hypotrichosis have been described. All these ten forms of hypotrichosis have been mapped on different human chromosomes and the corresponding genes have been identified in most of these cases. In the present study, we have described a six-generation Pakistani consanguineous family with an autosomal recessive transmission of hereditary hypotrichosis. All the five affected individuals of the family showed complete absence of scalp hair and sparse eyebrows and eyelashes. They were born with complete absence of scalp hairs. Facial hair of beard and mustaches were present in all the affected adult male individuals. Papules were observed only on scalp of the affected individuals. A scalp biopsy from an affected individual showed markedly reduced number of hair follicles. Human genome scan using polymorphic microsatellite markers mapped the disease locus on chromosome 7p21.3-p22.3, flanked by markers D7S1532 and D7S3047. A maximum two-point LOD score of 4.74 (theta = 0.00) was obtained at marker D7S481. The linkage interval spans 15.69 cM, which corresponds to 6.59 Mb according to the sequence-based physical map (Build 36.2). Mutation analysis of five potential candidate genes (GNA12, FOXK1, DAGLB, ZNF12, ACTB), located in the linkage interval, did not reveal any functional sequence variant.
