Genes affected
KCNK15 (HGNC:13814): (potassium two pore domain channel subfamily K member 15) This gene encodes one of the members 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. [provided by RefSeq, Jul 2008]

The c.536C>T (p.S179L) alteration is located in exon 2 (coding exon 2) of the KCNK15 gene. This alteration results from a C to T substitution at nucleotide position 536, causing the serine (S) at amino acid position 179 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
