ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 13 ACMG points.

PM1
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 3 uncertain in NM_017807.4
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, 0.93
PP5
Variant 14-20452057-A-G is Pathogenic according to our data. Variant chr14-20452057-A-G is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 444887.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
