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]

RIMS2 Gene-Disease associations (from GenCC):

• cone-rod synaptic disorder syndrome, congenital nonprogressive

  Inheritance: AR Classification: STRONG, MODERATE Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics, G2P
• cone-rod synaptic disorder, congenital nonprogressive

  Inheritance: AR Classification: STRONG Submitted by: Franklin by Genoox

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.216 is higher than 0.05.
