The c.482G>A (p.R161H) alteration is located in exon 5 (coding exon 5) of the CHCHD6 gene. This alteration results from a G to A substitution at nucleotide position 482, causing the arginine (R) at amino acid position 161 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
