Ambry Genetics

Sep 26, 2023

The c.46G>A (p.G16S) alteration is located in exon 1 (coding exon 1) of the SMYD1 gene. This alteration results from a G to A substitution at nucleotide position 46, causing the glycine (G) at amino acid position 16 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
