Genes affected

CYC1 (HGNC:2579): (cytochrome c1) This gene encodes a subunit of the cytochrome bc1 complex, which plays an important role in the mitochondrial respiratory chain by transferring electrons from the Rieske iron-sulfur protein to cytochrome c. Mutations in this gene may cause mitochondrial complex III deficiency, nuclear type 6. [provided by RefSeq, Dec 2013]

The c.13G>A (p.A5T) alteration is located in exon 1 (coding exon 1) of the CYC1 gene. This alteration results from a G to A substitution at nucleotide position 13, causing the alanine (A) at amino acid position 5 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
