Genes affected
KCNIP4 (HGNC:30083): (potassium voltage-gated channel interacting protein 4) This gene encodes a member of the family of voltage-gated potassium (Kv) channel-interacting proteins (KCNIPs), which belong 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. This protein member also interacts with presenilin. Multiple alternatively spliced transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]
PACRGL (HGNC:28442): (parkin coregulated like)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2022The c.410A>G (p.N137S) alteration is located in exon 4 (coding exon 4) of the KCNIP4 gene. This alteration results from a A to G substitution at nucleotide position 410, causing the asparagine (N) at amino acid position 137 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
