LIPH gene autosomal recessive woolly hair hypotrichosis congenital alopecia frame-shift mutation next-generation sequencing Sanger sequencing ARWH hair loss genetic hair disorder

TLDR Researchers found a new mutation in the LIPH gene of a woman with a rare hair condition.

The study described a 32-year-old woman with autosomal recessive woolly hair/hypotrichosis (ARWH/H), a rare congenital alopecia. Using next-generation and Sanger sequencing, researchers identified a novel frame-shift mutation (NM_139248: c.686delinsGTAGAACCCAACCTGGCT: p.Asp229fs37X) and a previously reported mutation (NM_139248: exon6:c.T736A: p.C246S) in the LIPH gene. Hair microscopy revealed abnormal hair appearance. The findings expanded the known mutation spectrum of the LIPH gene and highlighted similarities in ARWH between Chinese and Japanese populations. No conflicts of interest were declared.
