Genes affected

RAD23B (HGNC:9813): (RAD23 homolog B, nucleotide excision repair protein) The protein encoded by this gene is one of two human homologs of Saccharomyces cerevisiae Rad23, a protein involved in the nucleotide excision repair (NER). This protein was found to be a component of the protein complex that specifically complements the NER defect of xeroderma pigmentosum group C (XP-c) cell extracts in vitro. This protein was also shown to interact with, and elevate the nucleotide excision activity of 3-methyladenine-DNA glycosylase (MPG), which suggested a role in DNA damage recognition in base excision repair. This protein contains an N-terminal ubiquitin-like domain, which was reported to interact with 26S proteasome, and thus this protein may be involved in the ubiquitin mediated proteolytic pathway in cells. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Sep 2011]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.503C>T (p.S168L) alteration is located in exon 5 (coding exon 5) of the RAD23B gene. This alteration results from a C to T substitution at nucleotide position 503, causing the serine (S) at amino acid position 168 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The RAD23B c.503C>T variant is predicted to result in the amino acid substitution p.Ser168Leu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.037% of alleles in individuals of Latino descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
