Summary Background Woodhouse–Sakati syndrome ( WSS ) is a rare neuroendocrine and ectodermal disorder inherited in an autosomal recessive pattern. The syndrome presents prominent clinical features, including alopecia, neuroendocrine defects, neurological findings and progressive hearing loss. The condition results from mutations in the DCAF 17 gene. Aims To search for the underlying genetic defect in a Pakistani family with WSS phenotypes. Methodology Whole exome sequencing was used to search for the disease‐causing variant. Results Analysis of the exome data revealed a start loss sequence variant (c.1A>G, p.M1?) in DCAF 17 . Conclusion This variant is predicted to abolish translation of the DCAF 17 polypeptide. To our knowledge, this is the first start loss variant identified in the DCAF 17 .
