Genes affected

KCNK10 (HGNC:6273): (potassium two pore domain channel subfamily K member 10) The protein encoded by this gene belongs to the family of potassium channel proteins containing two pore-forming P domains. This channel is an open rectifier which primarily passes outward current under physiological K+ concentrations, and is stimulated strongly by arachidonic acid and to a lesser degree by membrane stretching, intracellular acidification, and general anaesthetics. Several alternatively spliced transcript variants encoding different isoforms have been identified for this gene. [provided by RefSeq, Sep 2008]

The c.1132C>T (p.R378C) alteration is located in exon 7 (coding exon 7) of the KCNK10 gene. This alteration results from a C to T substitution at nucleotide position 1132, causing the arginine (R) at amino acid position 378 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
