dbSNP rs1012473029: MYOM3:p.Gly967Ala (chr1-24074228-C-G) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3

The NM_152372.4(MYOM3):c.2900G>C(p.Gly967Ala) variant causes a missense change. The variant allele was found at a frequency of 0.00000929 in 1,613,914 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 ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G967D) has been classified as Uncertain significance.
