ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

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.

BP4

Computational evidence support a benign effect (MetaRNN=0.35465115).

BS1

Variant frequency is greater than expected in population afr. gnomad4_exome allele frequency = 0.0000114 (16/1399000) while in subpopulation AFR AF= 0.000507 (16/31560). AF 95% confidence interval is 0.000317. There are 0 homozygotes in gnomad4_exome. There are 7 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 15 AD gene.

Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant has not been reported in the literature in individuals affected with GREB1L-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.05%). This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 33 of the GREB1L protein (p.Pro33Ala). -
