Wolcott–Rallison syndrome, WRS, is a rare, autosomal recessive disorder with infancy-onset diabetes mellitus, multiple epiphyseal dysplasia, osteopenia, mental retardation or developmental delay, and hepatic and renal dysfunction as main clinical findings. Patients with WRS have mutations in the EIF2AK3 gene, which encodes the eukaryotic translation initiation factor 2-alpha kinase 3. Other disease names include multiple epiphyseal dysplasia and early-onset diabetes mellitus. Most patients with this disease do not survive to adulthood . The majority of WRS patients die from fulminant hepatitis during childhood. There are few reported cases for this disease. Of the 54 families worldwide with reported WRS cases, 22.2% of them are from the Kingdom of Saudi Arabia. Of the 23 WRS patients in Saudi Arabia, all but one is the result of consanguineous marriages. Another country where WRS cases have been found is Kosovo. Here, the Albanian population is also known for consanguineous marriages, but there were some cases involving patients from non-consanguineous parents that were carriers for the same mutant allele.
