The c.820G>A (p.V274I) alteration is located in exon 4 (coding exon 4) of the SLC25A28 gene. This alteration results from a G to A substitution at nucleotide position 820, causing the valine (V) at amino acid position 274 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
