Genes affected

JPH1 (HGNC:14201): (junctophilin 1) Junctional complexes between the plasma membrane and endoplasmic/sarcoplasmic reticulum are a common feature of all excitable cell types and mediate cross talk between cell surface and intracellular ion channels. The protein encoded by this gene is a component of junctional complexes and is composed of a C-terminal hydrophobic segment spanning the endoplasmic/sarcoplasmic reticulum membrane and a remaining cytoplasmic domain that shows specific affinity for the plasma membrane. This gene is a member of the junctophilin gene family. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jan 23, 2023

The c.1295T>C (p.V432A) alteration is located in exon 4 (coding exon 4) of the JPH1 gene. This alteration results from a T to C substitution at nucleotide position 1295, causing the valine (V) at amino acid position 432 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
