Variant 18-49936289-G-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PM5PP3_StrongPP5

The NM_001080467.3(MYO5B):c.1966C>A(p.Arg656Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000998 in 1,603,906 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in Lovd as Likely pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R656C) has been classified as Pathogenic.
