Genes affected

GREB1L (HGNC:31042): (GREB1 like retinoic acid receptor coactivator) Acts upstream of or within kidney development. Predicted to be integral component of membrane. Implicated in autosomal dominant nonsyndromic deafness and renal agenesis. [provided by Alliance of Genome Resources, Apr 2022]

(HGNC:):

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 73 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
