The c.461A>C (p.E154A) alteration is located in exon 3 (coding exon 3) of the COQ5 gene. This alteration results from a A to C substitution at nucleotide position 461, causing the glutamic acid (E) at amino acid position 154 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
