Ambry Genetics

May 25, 2022

The c.925G>A (p.V309M) alteration is located in exon 8 (coding exon 8) of the L3MBTL2 gene. This alteration results from a G to A substitution at nucleotide position 925, causing the valine (V) at amino acid position 309 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
