Ambry Genetics

Feb 14, 2023

The c.3920G>A (p.G1307E) alteration is located in exon 13 (coding exon 13) of the LMTK3 gene. This alteration results from a G to A substitution at nucleotide position 3920, causing the glycine (G) at amino acid position 1307 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
