Ambry Genetics

Aug 23, 2021

The c.247A>G (p.M83V) alteration is located in exon 3 (coding exon 3) of the ECHDC1 gene. This alteration results from a A to G substitution at nucleotide position 247, causing the methionine (M) at amino acid position 83 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
