Genes affected

JSRP1 (HGNC:24963): (junctional sarcoplasmic reticulum protein 1) The protein encoded by this gene is involved in excitation-contraction coupling at the sarcoplasmic reticulum. The encoded protein can interact with CACNA1S, CACNB1, and calsequestrin to help regulate calcium influx and efflux in skeletal muscle. [provided by RefSeq, Jul 2012]

Ambry Genetics

Jun 21, 2022

The c.325C>T (p.P109S) alteration is located in exon 5 (coding exon 4) of the JSRP1 gene. This alteration results from a C to T substitution at nucleotide position 325, causing the proline (P) at amino acid position 109 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
