ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

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.

BP4

Computational evidence support a benign effect (MetaRNN=0.25743717).

BP6

Variant 14-20447434-C-T is Benign according to our data. Variant chr14-20447434-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 1915192.
