Genes affected

RNF19B (HGNC:26886): (ring finger protein 19B) This gene encodes a multi-pass membrane protein containing two RING-type and one IBR-type zinc finger motifs. The encoded protin is an E3 ubiquitin-protein ligase that plays a role in the cytotoxic effects of natural killer (NK) cells. Alternative splicing results in multiple transcript variants. There are pseudogenes for this gene on chromosomes X and Y in a possible pseudoautosomal region. [provided by RefSeq, Jul 2014]

Collection Method: clinical testing

The c.2152G>A (p.E718K) alteration is located in exon 9 (coding exon 9) of the RNF19B gene. This alteration results from a G to A substitution at nucleotide position 2152, causing the glutamic acid (E) at amino acid position 718 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
