Genes affected

KCNK7 (HGNC:6282): (potassium two pore domain channel subfamily K member 7) This gene encodes a member of the superfamily of potassium channel proteins containing two pore-forming P domains. The product of this gene has not been shown to be a functional channel; however, it may require other non-pore-forming proteins for activity. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Feb 12, 2024

The c.413C>T (p.A138V) alteration is located in exon 2 (coding exon 2) of the KCNK7 gene. This alteration results from a C to T substitution at nucleotide position 413, causing the alanine (A) at amino acid position 138 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
