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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2023The c.988C>T (p.R330W) alteration is located in exon 7 (coding exon 6) of the JSRP1 gene. This alteration results from a C to T substitution at nucleotide position 988, causing the arginine (R) at amino acid position 330 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
