Genes affected

KCNJ9 (HGNC:6270): (potassium inwardly rectifying channel subfamily J member 9) 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, which has a greater tendency to allow potassium to flow into a cell rather than out of a cell, is controlled by G-proteins. It associates with another G-protein-activated potassium channel to form a heteromultimeric pore-forming complex. [provided by RefSeq, Jul 2008]

The c.29C>T (p.P10L) alteration is located in exon 2 (coding exon 1) of the KCNJ9 gene. This alteration results from a C to T substitution at nucleotide position 29, causing the proline (P) at amino acid position 10 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
