Comment when marking as ready: Associated with phenotype in OMIM and G2P. At least three variants reported

Created: 5 Aug 2016, 11:55 a.m.

Comment on list classification: Promoted to green due to additional evidence provided by a second reviewer - PMID:26235987 reports 3 different loss-of-function variants in 3 unrelated families. It is a probable DD gene for CAKUT.

Green List (high evidence)

One publication in 2015 showing mutations in three unrelated families with a variety of renal malformations (hydronephrosis, vescicoureteric reflux and small kidneys). In mice, biallelic null mutations cause major ureter malformations.
