The c.1409G>A (p.R470Q) alteration is located in exon 13 (coding exon 13) of the UQCRC1 gene. This alteration results from a G to A substitution at nucleotide position 1409, causing the arginine (R) at amino acid position 470 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
