Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1 PM2 PM5 PP3_Moderate PP5_Moderate

The NM_001042681.2(RERE):​c.4297C>T​(p.His1433Tyr) 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 Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H1433D) 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 10 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, 1 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 chr1-8358238-G-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 521311.We mark this variant Likely_pathogenic, oryginal submissions are: {Uncertain_significance=1, Likely_pathogenic=1}.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.855
• PP5: Variant 1-8358238-G-A is Pathogenic according to our data. Variant chr1-8358238-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 1686749.Status of the report is criteria_provided_single_submitter, 1 stars.
