Description

The c.1339C>G (p.L447V) alteration is located in exon 11 (coding exon 10) of the MGAM gene. This alteration results from a C to G substitution at nucleotide position 1339, causing the leucine (L) at amino acid position 447 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
