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 Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), GREB1L. . Gene score misZ 5.3659 (greater than the threshold 3.09). Trascript score misZ 5.6738 (greater than threshold 3.09). GenCC has associacion of gene with bilateral renal agenesis, renal hypodysplasia/aplasia 3, renal agenesis, unilateral, hearing loss, autosomal dominant 80.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.802
