Genes affected

RNF168 (HGNC:26661): (ring finger protein 168) This gene encodes an E3 ubiquitin ligase protein that contains a RING finger, a motif present in a variety of functionally distinct proteins and known to be involved in protein-DNA and protein-protein interactions. The protein is involved in DNA double-strand break (DSB) repair. Mutations in this gene result in Riddle syndrome. [provided by RefSeq, Sep 2011]

RNF168 NM_152617.3 exon 6 p.Asn532Serfs*2 (c.1591_1594dup):This variant has not been reported in the literature but is present in 0.02% (1/4832) of South Asian alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/3-196471940-T-TTAAC?dataset=gnomad_r3). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. This variant is a duplication of 4 nucleotides at position 1591 and creates a premature stop codon 2 amino acids downstream from this location which results in an absent or abnormal protein. Loss of function variants have been reported in association with disease for this gene (Pietrucha 2017 PMID:29255463). However, this variant occurs within the last exon of this gene; due to its position, it is possible that this protein may escape nonsense mediated decay. Further studies are needed to understand its impact. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
