Description

In 2 sibs, born of consanguineous Arab parents, with nephrotic syndrome type 9 (NPHS9; 615573), Ashraf et al. (2013) identified a homozygous c.532C-T transition in exon 7 of the ADCK4 gene, resulting in an arg178-to-trp (R178W) substitution at a highly conserved residue. The mutation was found by homozygosity mapping combined with whole-exome sequencing and segregated with the disorder in the family. It was not present in over 190 ethnically matched controls or in the Exome Variant Server database. Functional studies were not performed. The patients had onset of steroid-resistant nephrotic syndrome at ages 7 and 13 years, respectively, and underwent renal transplantation at ages 10 and 15 years, respectively.
