Genes affected

RIMS1 (HGNC:17282): (regulating synaptic membrane exocytosis 1) The protein encoded by this gene is a RAS gene superfamily member that regulates synaptic vesicle exocytosis. This gene also plays a role in the regulation of voltage-gated calcium channels during neurotransmitter and insulin release. Mutations have suggested a role cognition and have been identified as the cause of cone-rod dystrophy type 7. Multiple transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Mar 2012]

ACMG classification

Verdict is Benign. Variant got -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.7).
• BP6: Variant 6-72179751-G-A is Benign according to our data. Variant chr6-72179751-G-A is described in ClinVar as [Benign]. Clinvar id is 260499.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr6-72179751-G-A is described in Lovd as [Benign].
• BP7: Synonymous conserved (PhyloP=-3.24 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00765 (1165/152196) while in subpopulation AFR AF= 0.026 (1080/41532). AF 95% confidence interval is 0.0247. There are 15 homozygotes in gnomad4. There are 564 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1165 AD gene.

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
