Position:

• chr1-214318943-G-C

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_020197.3(SMYD2):​c.494G>C​(p.Gly165Ala) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G165E) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 30)
• Consequence: SMYD2 NM_020197.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 4.95

Genes affected

SMYD2 (HGNC:20982): (SET and MYND domain containing 2) SET domain-containing proteins, such as SMYD2, catalyze lysine methylation (Brown et al., 2006 [PubMed 16805913]).[supplied by OMIM, Nov 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.083951324).
