The c.908G>A (p.G303E) alteration is located in exon 6 (coding exon 6) of the ECHDC1 gene. This alteration results from a G to A substitution at nucleotide position 908, causing the glycine (G) at amino acid position 303 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
