Genes affected

KCNJ15 (HGNC:6261): (potassium inwardly rectifying channel subfamily J member 15) Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. The protein encoded by this gene is an integral membrane protein and inward-rectifier type potassium channel. The encoded protein has a greater tendency to allow potassium to flow into a cell rather than out of a cell. Eight transcript variants encoding the same protein have been found for this gene.

The c.805C>A (p.P269T) alteration is located in exon 3 (coding exon 1) of the KCNJ15 gene. This alteration results from a C to A substitution at nucleotide position 805, causing the proline (P) at amino acid position 269 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
