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 was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

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 the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. 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. -
