• Consequence: MT-ND6 ENST00000361681.2 synonymous
• Clinical Significance: Uncertain significance no assertion criteria provided U:1 No linked disesase in Mitomap
• Conservation: PhyloP100: -20.0

Genes affected

MT-ND6 (HGNC:7462): (mitochondrially encoded NADH dehydrogenase 6) Enables NADH dehydrogenase (ubiquinone) activity. Involved in mitochondrial electron transport, NADH to ubiquinone and mitochondrial respiratory chain complex I assembly. Predicted to be located in mitochondrial inner membrane. Implicated in Leber hereditary optic neuropathy; Leigh disease; and spinal muscular atrophy with lower extremity predominante 2B. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• BP7: Synonymous conserved (PhyloP=-20 with no splicing effect.
• BS2: High AC in GnomadMitoHomoplasmic at 9
