Genes affected

RIMS2 (HGNC:17283): (regulating synaptic membrane exocytosis 2) The protein encoded by this gene is a presynaptic protein that interacts with RAB3, a protein important for normal neurotransmitter release. The encoded protein can also bind several other synaptic proteins, including UNC-13 homolog B, ELKS/Rab6-interacting/CAST family member 1, and synaptotagmin 1. This protein is involved in synaptic membrane exocytosis. Polymorphisms in this gene have been associated with degenerative lumbar scoliosis. [provided by RefSeq, Feb 2017]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.07930502).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000105 (16/152180) while in subpopulation AFR AF= 0.000362 (15/41442). AF 95% confidence interval is 0.000222. There are 0 homozygotes in gnomad4. There are 5 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.589T>C (p.S197P) alteration is located in exon 3 (coding exon 3) of the RIMS2 gene. This alteration results from a T to C substitution at nucleotide position 589, causing the serine (S) at amino acid position 197 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
