The c.261T>G (p.S87R) alteration is located in exon 2 (coding exon 2) of the COQ5 gene. This alteration results from a T to G substitution at nucleotide position 261, causing the serine (S) at amino acid position 87 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
