The c.964G>A (p.E322K) alteration is located in exon 10 (coding exon 10) of the SMYD2 gene. This alteration results from a G to A substitution at nucleotide position 964, causing the glutamic acid (E) at amino acid position 322 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
