Ambry Genetics

Oct 26, 2022

The c.97G>T (p.V33F) alteration is located in exon 5 (coding exon 1) of the MGAT4C gene. This alteration results from a G to T substitution at nucleotide position 97, causing the valine (V) at amino acid position 33 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
