The c.628G>A (p.A210T) alteration is located in exon 7 (coding exon 7) of the ECHDC2 gene. This alteration results from a G to A substitution at nucleotide position 628, causing the alanine (A) at amino acid position 210 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
