Genes affected

KCNIP3 (HGNC:15523): (potassium voltage-gated channel interacting protein 3) This gene encodes a member of the family of voltage-gated potassium (Kv) channel-interacting proteins, which belong to the recoverin branch of the EF-hand superfamily. Members of this family are small calcium binding proteins containing EF-hand-like domains. They are integral subunit components of native Kv4 channel complexes that may regulate A-type currents, and hence neuronal excitability, in response to changes in intracellular calcium. The encoded protein also functions as a calcium-regulated transcriptional repressor, and interacts with presenilins. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

The c.712G>T (p.A238S) alteration is located in exon 8 (coding exon 8) of the KCNIP3 gene. This alteration results from a G to T substitution at nucleotide position 712, causing the alanine (A) at amino acid position 238 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
