Genes affected
KCNK16 (HGNC:14464): (potassium two pore domain channel subfamily K member 16) 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 expressed predominantly in the pancreas and is activated at alkaline pH. Several alternatively spliced transcript variants encoding different isoforms have been identified for this gene. [provided by RefSeq, Sep 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2024The c.320C>G (p.T107S) alteration is located in exon 2 (coding exon 2) of the KCNK16 gene. This alteration results from a C to G substitution at nucleotide position 320, causing the threonine (T) at amino acid position 107 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
