ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 13 ACMG points.

PVS1

Splicing variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 4, offset of 1, new splice context is: tttgtttatgtttctctaAGtca. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.

PM2

Very rare variant in population databases, with high coverage;

PP3

Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF, max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.

PP5

Variant 7-2573417-G-A is Pathogenic according to our data. Variant chr7-2573417-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 437834.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr7-2573417-G-A is described in Lovd as [Pathogenic].
