Abstract
Wolcott-Rallison syndrome (WRS) is a rare genetic autosomal recessive inherited disorder with three main clinical features: neonatal diabetes mellitus (NDM), bone dysplasia, and acute liver dysfunction. The aim of the study is to report a rare case of WRS with genetic analysis. We report a 1-year-old male patient with consanguineous parents who was referred due to weakness and vomiting at 3 months old and was admitted due to diabetic ketoacidosis with severe acidosis and hyperglycemia without any other skeletal, hepatic, or renal presentations and a novel homozygous c.2825A>C (p.Asn942Thr) variant in exon 14 of the EIF2AK3 gene on chromosome 2. Genetic testing is recommended for distinguishing WRS from other causes of neonatal insulin-dependent diabetes, and early diagnosis in order to develop timely and appropriate treatment, especially rapid detection of the acute liver failure as the most life-threatening complication.
