Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Mitomap GenBank: Absent
• Consequence: TRNS1 frameshift
• Clinical Significance: Not reported in ClinVar No linked disesase in Mitomap
• Conservation: PhyloP100: -1.71

Genes affected

TRNS1 (HGNC:7497): (mitochondrially encoded tRNA serine 1 (UCN))

TRND (HGNC:7478): (mitochondrially encoded tRNA aspartic acid)

COX1 (HGNC:7419): (mitochondrially encoded cytochrome c oxidase I) Contributes to cytochrome-c oxidase activity. Predicted to be involved in electron transport coupled proton transport and mitochondrial electron transport, cytochrome c to oxygen. Part of mitochondrial respiratory chain complex III and mitochondrial respiratory chain complex IV. [provided by Alliance of Genome Resources, Apr 2022]
