Genes affected

RNF128 (HGNC:21153): (ring finger protein 128) The protein encoded by this gene is a type I transmembrane protein that localizes to the endocytic pathway. This protein contains a RING zinc-finger motif and has been shown to possess E3 ubiquitin ligase activity. Expression of this gene in retrovirally transduced T cell hybridoma significantly inhibits activation-induced IL2 and IL4 cytokine production. Induced expression of this gene was observed in anergic CD4(+) T cells, which suggested a role in the induction of anergic phenotype. Alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.23G>A (p.G8E) alteration is located in exon 1 (coding exon 1) of the RNF128 gene. This alteration results from a G to A substitution at nucleotide position 23, causing the glycine (G) at amino acid position 8 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
