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]

The c.1479G>C (p.L493F) alteration is located in exon 7 (coding exon 7) of the RNF19B gene. This alteration results from a G to C substitution at nucleotide position 1479, causing the leucine (L) at amino acid position 493 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
