Whole-exome sequencing analysis revealed compound heterozygous variants in the <i>FAT4</i> gene. Recessive variants in <i>FAT4</i> are a known cause of van Maldergem syndrome (VMS) in which congenital anomalies of the kidney and urinary tract are a less characteristic but common feature. The initial presentation of our patient was not clinically recognizable. However, in view of the molecular findings, the most likely diagnosis is a mild manifestation of VMS. Only very few publications have reported patients with VMS and mutations in <i>FAT4 </i>to date. With this case, we hope to provide further insight into the phenotypic variability of this syndrome. 2017-06-30 11:55:50 FAT4 Syndromic CAKUT Van Maldergem syndrome Whole-exome sequencing
