Abstract Woodhouse-Sakati syndrome (WSS) is a rare eponymous disease described by Drs. Woodhouse and Sakati in 1983 as a syndrome of hypogonadism, alopecia, diabetes mellitus, intellectual disability, and ECG abnormalities. A couple of years later, a variant in the gene DCAF17 (DDB1 and CUL4-associated factor 17) was labeled as the founder mutation in most cases of WSS in the Arabian Peninsula and the Middle East. Reports around the world started to emerge on variable presentations of the syndrome, expanding its phenotypic spectrum. In addition, the discovery of new variants in the same gene grew our understanding of this multi-systemic syndrome. Genotype and phenotype expansion is increasing with the growing number of diagnosed cases owing to the availability and advances in clinical genetic testing. This review describes the current understanding of the DCAF17 gene with its molecular implication in WSS. We also provide an extensive analysis of the documented genetic changes associated with the syndrome, describing the geographical prevalence of these genetic variations. Additionally, we examine the disorder’s extensive manifestations and clinical presentations and describe a case of intra-familial phenotypic heterogeneity.
