Genes affected

RNF122 (HGNC:21147): (ring finger protein 122) The encoded protein contains a RING finger, a motif present in a variety of functionally distinct proteins and known to be involved in protein-protein and protein-DNA interactions. The encoded protein is localized to the endoplasmic reticulum and golgi apparatus, and may be associated with cell viability. [provided by RefSeq, Jul 2013]

Collection Method: clinical testing

The c.127G>A (p.G43S) alteration is located in exon 2 (coding exon 2) of the RNF122 gene. This alteration results from a G to A substitution at nucleotide position 127, causing the glycine (G) at amino acid position 43 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
