Variant chr17-1786959-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 2P and 3B. PM2BP4_ModerateBP6

The ENST00000305513.12(SMYD4):c.1735C>T(p.Arg579Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000942 in 1,613,820 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R579Q) has been classified as Likely benign.

The c.1735C>T (p.R579W) alteration is located in exon 7 (coding exon 6) of the SMYD4 gene. This alteration results from a C to T substitution at nucleotide position 1735, causing the arginine (R) at amino acid position 579 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
