Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The ENST00000361227.2(MT-ND3):ā€‹c.178A>Gā€‹(p.Ile60Val) variant causes a missense change. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I60T) has been classified as Benign.
