Ambry Genetics

Mar 01, 2023

The c.725C>T (p.A242V) alteration is located in exon 7 (coding exon 3) of the MGAT4C gene. This alteration results from a C to T substitution at nucleotide position 725, causing the alanine (A) at amino acid position 242 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
