Genes affected

RNF133 (HGNC:21154): (ring finger protein 133) The protein encoded by this gene contains a RING finger domain, a motif present in a variety of functionally distinct proteins and known to be involved in protein-protein and protein-DNA interactions. This gene has no intron. [provided by RefSeq, Jul 2008]

RNF133 links:

CADPS2 (HGNC:16018): (calcium dependent secretion activator 2) This gene encodes a member of the calcium-dependent activator of secretion (CAPS) protein family, which are calcium binding proteins that regulate the exocytosis of synaptic and dense-core vesicles in neurons and neuroendocrine cells. Mutations in this gene may contribute to autism susceptibility. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2009]

Ambry Genetics

Jun 06, 2023

The c.802A>G (p.I268V) alteration is located in exon 1 (coding exon 1) of the RNF133 gene. This alteration results from a A to G substitution at nucleotide position 802, causing the isoleucine (I) at amino acid position 268 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
