ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.

BP6

Variant 11-61398269-G-C is Benign according to our data. Variant chr11-61398269-G-C is described in ClinVar as Benign. ClinVar VariationId is 126297.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BA1

GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.948 is higher than 0.05.
