Genes affected

RAD23A (HGNC:9812): (RAD23 homolog A, nucleotide excision repair protein) The protein encoded by this gene is one of two human homologs of Saccharomyces cerevisiae Rad23, a protein involved in nucleotide excision repair. Proteins in this family have a modular domain structure consisting of an ubiquitin-like domain (UbL), ubiquitin-associated domain 1 (UbA1), XPC-binding domain and UbA2. The protein encoded by this gene plays an important role in nucleotide excision repair and also in delivery of polyubiquitinated proteins to the proteasome. Alternative splicing results in multiple transcript variants encoding multiple isoforms. [provided by RefSeq, Jun 2012]

Collection Method: clinical testing

The c.191A>G (p.Y64C) alteration is located in exon 2 (coding exon 2) of the RAD23A gene. This alteration results from a A to G substitution at nucleotide position 191, causing the tyrosine (Y) at amino acid position 64 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
