Ambry Genetics

Sep 27, 2021

The c.1181G>A (p.G394D) alteration is located in exon 11 (coding exon 11) of the LAP3 gene. This alteration results from a G to A substitution at nucleotide position 1181, causing the glycine (G) at amino acid position 394 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
