Variant summary

Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PM1 PM2 PM5 PP3_Moderate PP5_Very_Strong

The NM_001042681.2(RERE):c.4304A>T(p.His1435Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H1435R) has been classified as Likely pathogenic.

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 Pathogenic. Variant got 16 ACMG points.

• PM1: In a hotspot region, there are 5 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 3 uncertain in NM_001042681.2
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr1-8358231-T-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 522858.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.911
• PP5: Variant 1-8358231-T-A is Pathogenic according to our data. Variant chr1-8358231-T-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 452391.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-8358231-T-A is described in Lovd as [Pathogenic].

The H1435L variant in the RERE gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The H1435L variant is not observed in large population cohorts (Lek et al., 2016). The H1435L 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 H1435L as a likely pathogenic variant. -
