ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 20 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 5.1, offset of 4, new splice context is: tgtcgtgttttcccaaaaAGagc. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.

PS3

PS3 evidence extracted from ClinVar submissions: SCV000747037: In summary, the c.826-1G>A variant meets the ACMG criteria to be classified as pathogenic based upon segregation studies, population frequency data and functional evidence.

PP5

Variant 1-155672732-C-T is Pathogenic according to our data. Variant chr1-155672732-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 523660.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
