A Case of Wiedemann-Rautenstrauch Syndrome With Fatal Hyperkalemic Renal Failure

Wiedemann-Rautenstrauch Syndrome (WRS), also known as neonatal progeroid syndrome, is an extremely rare genetic syndrome characterized by a senile appearance at birth with multiple complex symptoms. We reported a case of a three-days old male neonate with features of WRS presented with fatal hyperkalemic renal failure which is a unique presentation not reported before in the cases affected with this syndrome. There is a positive family history of a previous sibling with the same features who suddenly died during the first week of life. This case report aimed to increase the awareness of WRS about the features and the importance of close follow-up of the affected cases, especially in the neonatal period among neonatal physicians.
