Variant summary

Our verdict is Pathogenic. The variant received 10 ACMG points: 11P and 1B. PM1 PP3 PP5_Very_Strong BP3

The NM_001042681.2(RERE):​c.4307_4318delTCCACCTCCACC​(p.Leu1436_His1439del) variant causes a disruptive inframe deletion change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar 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

Our verdict: Pathogenic. The variant received 10 ACMG points.

• PM1: In a hotspot region, there are 11 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 3 uncertain in NM_001042681.2
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
• PP5: Variant 1-8358216-TGGTGGAGGTGGA-T is Pathogenic according to our data. Variant chr1-8358216-TGGTGGAGGTGGA-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 2442107.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP3: Nonframeshift variant in repetitive region in NM_001042681.2
