Variant summary

Our verdict is Benign. Variant got -7 ACMG points: 0P and 7B. BP4 BP6_Moderate BS2

The ENST00000361335.1(MT-ND4L):​c.185C>T​(p.Ala62Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. In-silico tool predicts a benign outcome for this variant. 7/10 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A62T) has been classified as Benign.
