Genes affected

RNF123 (HGNC:21148): (ring finger protein 123) The protein encoded by this gene contains a C-terminal RING finger domain, a motif present in a variety of functionally distinct proteins and known to be involved in protein-protein and protein-DNA interactions, and an N-terminal SPRY domain. This protein displays E3 ubiquitin ligase activity toward the cyclin-dependent kinase inhibitor 1B which is also known as p27 or KIP1. Alternative splicing results in multiple transcript variants.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.820C>T (p.R274W) alteration is located in exon 11 (coding exon 10) of the RNF123 gene. This alteration results from a C to T substitution at nucleotide position 820, causing the arginine (R) at amino acid position 274 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
