Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4 BP6_Very_Strong BS2

The ENST00000361851.1(MT-ATP8):​c.154G>A​(p.Glu52Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E52G) has been classified as Likely benign.
