Ambry Genetics

Nov 12, 2021

The c.325C>T (p.R109C) alteration is located in exon 3 (coding exon 3) of the SMYD1 gene. This alteration results from a C to T substitution at nucleotide position 325, causing the arginine (R) at amino acid position 109 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
