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]

COA1 links:

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]

The c.419G>A (p.G140D) alteration is located in exon 6 (coding exon 5) of the COA1 gene. This alteration results from a G to A substitution at nucleotide position 419, causing the glycine (G) at amino acid position 140 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
