Genetic Variant SVOPL:p.Asp326His (chr7-138628251-C-G) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001139456.2(SVOPL):c.976G>C(p.Asp326His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000273 in 1,613,946 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 17/22 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. D326Y) has been classified as Uncertain significance.

Genes affected

SVOPL (HGNC:27034): (SVOP like) The protein encoded by this gene is thought to be a member of solute carrier family 22, which includes transmembrane proteins that transport toxins and drugs from the body. This gene is a paralog of the SVOP gene that encodes synaptic vesicle 2-related protein. [provided by RefSeq, Sep 2016]
