The c.630C>G (p.H210Q) alteration is located in exon 2 (coding exon 1) of the SLC25A53 gene. This alteration results from a C to G substitution at nucleotide position 630, causing the histidine (H) at amino acid position 210 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
