Genes affected

UVSSA (HGNC:29304): (UV stimulated scaffold protein A) The protein encoded by this gene appears to be involved in ubiquitination and dephosphorylation of RNA polymerase II subunits that stall after UV irradiation. The encoded protein interacts with several members of the nucleotide excision repair complex, and is thought to be involved in the transcription-coupled nucleotide excision repair (TC-NER) pathway to help remove lesions in the DNA that block transcription. Defects in this gene can cause UV-sensitive syndrome 3. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]

The c.343C>G (p.R115G) alteration is located in exon 3 (coding exon 2) of the UVSSA gene. This alteration results from a C to G substitution at nucleotide position 343, causing the arginine (R) at amino acid position 115 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
