Genetic Variant NM_014981.3:c.5611A>G (chr3-108384707-T-C) – 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_014981.3(MYH15):c.5611A>G(p.Lys1871Glu) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,461,498 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K1871N) has been classified as Uncertain significance.
