Genes affected

KCNK5 (HGNC:6280): (potassium two pore domain channel subfamily K member 5) This gene encodes one of the members of the superfamily of potassium channel proteins containing two pore-forming P domains. The message for this gene is mainly expressed in the cortical distal tubules and collecting ducts of the kidney. The protein is highly sensitive to external pH and this, in combination with its expression pattern, suggests it may play an important role in renal potassium transport.

The c.541G>A (p.V181I) alteration is located in exon 4 (coding exon 4) of the KCNK5 gene. This alteration results from a G to A substitution at nucleotide position 541, causing the valine (V) at amino acid position 181 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
