The c.161G>A (p.G54D) alteration is located in exon 2 (coding exon 2) of the CHCHD6 gene. This alteration results from a G to A substitution at nucleotide position 161, causing the glycine (G) at amino acid position 54 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
