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]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.987

The c.1297G>A (p.G433R) alteration is located in exon 13 (coding exon 13) of the SVOPL gene. This alteration results from a G to A substitution at nucleotide position 1297, causing the glycine (G) at amino acid position 433 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
