Collection Method: clinical testing

The c.2159C>T (p.T720I) alteration is located in exon 10 (coding exon 9) of the SMYD4 gene. This alteration results from a C to T substitution at nucleotide position 2159, causing the threonine (T) at amino acid position 720 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
