Genes affected

KCNK17 (HGNC:14465): (potassium two pore domain channel subfamily K member 17) 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. This gene is activated at alkaline pH. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2008]

The c.487G>A (p.A163T) alteration is located in exon 3 (coding exon 3) of the KCNK17 gene. This alteration results from a G to A substitution at nucleotide position 487, causing the alanine (A) at amino acid position 163 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
