Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The ENST00000305513.12(SMYD4):c.2035C>T(p.Arg679Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000354 in 1,609,458 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R679Q) has been classified as Likely benign.

Mar 08, 2024

The c.2035C>T (p.R679W) alteration is located in exon 9 (coding exon 8) of the SMYD4 gene. This alteration results from a C to T substitution at nucleotide position 2035, causing the arginine (R) at amino acid position 679 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
