Genes affected

KCNIP1 (HGNC:15521): (potassium voltage-gated channel interacting protein 1) This gene encodes a member of the family of cytosolic voltage-gated potassium (Kv) channel-interacting proteins (KCNIPs), which belong to the neuronal calcium sensor (NCS) family of the calcium binding EF-hand proteins. They associate with Kv4 alpha subunits to form native Kv4 channel complexes. The encoded protein may regulate rapidly inactivating (A-type) currents, and hence neuronal membrane excitability, in response to changes in the concentration of intracellular calcium. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2013]

The c.559G>A (p.D187N) alteration is located in exon 7 (coding exon 7) of the KCNIP1 gene. This alteration results from a G to A substitution at nucleotide position 559, causing the aspartic acid (D) at amino acid position 187 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
