Genes affected

RERE (HGNC:9965): (arginine-glutamic acid dipeptide repeats) This gene encodes a member of the atrophin family of arginine-glutamic acid (RE) dipeptide repeat-containing proteins. The encoded protein co-localizes with a transcription factor in the nucleus, and its overexpression triggers apoptosis. A similar protein in mouse associates with histone deacetylase and is thought to function as a transcriptional co-repressor during embryonic development. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

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, 0.87
• PP5: Variant 1-8355536-A-T is Pathogenic according to our data. Variant chr1-8355536-A-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 452752.Status of the report is criteria_provided_single_submitter, 1 stars.

The L1517Q variant in the RERE gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The variant is not observed in large population cohorts (Lek et al., 2016). The variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret L1517Q as a likely pathogenic variant. -
