Genes affected

COA1 (HGNC:21868): (cytochrome c oxidase assembly factor 1) Involved in mitochondrial cytochrome c oxidase assembly and mitochondrial respiratory chain complex I assembly. Located in cytosol and mitochondrion. Is integral component of mitochondrial inner membrane. [provided by Alliance of Genome Resources, Apr 2022]

STK17A (HGNC:11395): (serine/threonine kinase 17a) This gene is a member of the DAP kinase-related apoptosis-inducing protein kinase family and encodes an autophosphorylated nuclear protein with a protein kinase domain. The protein has apoptosis-inducing activity. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.20443943).

The c.98T>A (p.V33E) alteration is located in exon 3 (coding exon 2) of the COA1 gene. This alteration results from a T to A substitution at nucleotide position 98, causing the valine (V) at amino acid position 33 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
