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.1501G>C (p.G501R) alteration is located in exon 6 (coding exon 4) of the JPH4 gene. This alteration results from a G to C substitution at nucleotide position 1501, causing the glycine (G) at amino acid position 501 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
