ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 7 ACMG points.

PM1
In a binding_site (size 0) in uniprot entity OSGEP_HUMAN
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 15 curated pathogenic missense variants (we use a threshold of 10). The gene has 2 curated benign missense variants. Gene score misZ: 0.75927 (below the threshold of 3.09). Trascript score misZ: 1.0429 (below the threshold of 3.09). GenCC associations: The gene is linked to Galloway-Mowat syndrome 3, Galloway-Mowat syndrome.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.863
