Genes affected

RNF40 (HGNC:16867): (ring finger protein 40) The protein encoded by this gene contains a RING finger, a motif known to be involved in protein-protein and protein-DNA interactions. This protein was reported to interact with the tumor suppressor protein RB1. Studies of the rat counterpart suggested that this protein may function as an E3 ubiquitin-protein ligase, and facilitate the ubiquitination and degradation of syntaxin 1, which is an essential component of the neurotransmitter release machinery. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2011]

The c.184C>T (p.R62W) alteration is located in exon 3 (coding exon 2) of the RNF40 gene. This alteration results from a C to T substitution at nucleotide position 184, causing the arginine (R) at amino acid position 62 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
