Variant summary

Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PS1 PM1 PM2 PP3_Moderate PP5_Very_Strong

The NM_001042681.2(RERE):​c.4293C>A​(p.His1431Gln) variant causes a missense change. 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 nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin Lovd.

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 18 ACMG points.

• PS1: Transcript NM_001042681.2 (RERE) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in Lovd
• PM1: In a hotspot region, there are 6 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 0 uncertain in NM_001042681.2
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.889
• PP5: Variant 1-8358242-G-T is Pathogenic according to our data. Variant chr1-8358242-G-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 224822.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-8358242-G-T is described in Lovd as [Likely_pathogenic].
