Ambry Genetics

Dec 01, 2022

The c.593C>T (p.A198V) alteration is located in exon 5 (coding exon 5) of the DTYMK gene. This alteration results from a C to T substitution at nucleotide position 593, causing the alanine (A) at amino acid position 198 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
