Genes affected

SCO1 (HGNC:10603): (synthesis of cytochrome C oxidase 1) Mammalian cytochrome c oxidase (COX) catalyzes the transfer of reducing equivalents from cytochrome c to molecular oxygen and pumps protons across the inner mitochondrial membrane. In yeast, 2 related COX assembly genes, SCO1 and SCO2 (synthesis of cytochrome c oxidase), enable subunits 1 and 2 to be incorporated into the holoprotein. This gene is the human homolog to the yeast SCO1 gene. [provided by RefSeq, Jul 2008]

The c.848A>G (p.K283R) alteration is located in exon 6 (coding exon 6) of the SCO1 gene. This alteration results from a A to G substitution at nucleotide position 848, causing the lysine (K) at amino acid position 283 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
