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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2022The c.389G>A (p.R130H) 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 389, causing the arginine (R) at amino acid position 130 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
