Ambry Genetics

Jan 31, 2024

The c.32T>A (p.V11D) alteration is located in exon 1 (coding exon 1) of the SMYD1 gene. This alteration results from a T to A substitution at nucleotide position 32, causing the valine (V) at amino acid position 11 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
