Genes affected

JPH4 (HGNC:20156): (junctophilin 4) This gene encodes a member of the junctophilin family of transmembrane proteins that are involved in the formation of the junctional membrane complexes between the plasma membrane and the endoplasmic/sarcoplasmic reticulum in excitable cells. The encoded protein contains a conserved N-terminal repeat region called the membrane occupation and recognition nexus sequence that is found in other members of the junctophilin family. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2009]

The c.1792C>A (p.P598T) alteration is located in exon 6 (coding exon 4) of the JPH4 gene. This alteration results from a C to A substitution at nucleotide position 1792, causing the proline (P) at amino acid position 598 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
