ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 3 uncertain in NM_017807.4

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.

PP5

Variant 14-20452053-A-G is Pathogenic according to our data. Variant chr14-20452053-A-G is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 444891.Status of the report is no_assertion_criteria_provided, 0 stars.
