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 GeneticsJun 17, 2024The c.400G>A (p.V134M) alteration is located in exon 5 (coding exon 4) of the JSRP1 gene. This alteration results from a G to A substitution at nucleotide position 400, causing the valine (V) at amino acid position 134 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
