Genes affected

KCNIP2 (HGNC:15522): (potassium voltage-gated channel interacting protein 2) This gene encodes a member of the family of voltage-gated potassium (Kv) channel-interacting proteins (KCNIPs), which belongs to the recoverin branch of the EF-hand superfamily. Members of the KCNIP family are small calcium binding proteins. They all have EF-hand-like domains, and differ from each other in the N-terminus. They are integral subunit components of native Kv4 channel complexes. They may regulate A-type currents, and hence neuronal excitability, in response to changes in intracellular calcium. Multiple alternatively spliced transcript variants encoding distinct isoforms have been identified from this gene. [provided by RefSeq, Jul 2008]

The c.355C>T (p.R119C) alteration is located in exon 4 (coding exon 4) of the KCNIP2 gene. This alteration results from a C to T substitution at nucleotide position 355, causing the arginine (R) at amino acid position 119 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
