Jun 29, 2022

The c.2009A>T (p.D670V) alteration is located in exon 8 (coding exon 7) of the SMYD4 gene. This alteration results from a A to T substitution at nucleotide position 2009, causing the aspartic acid (D) at amino acid position 670 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
