Rhabdomyolysis and Metabolic Myopathy v0.119 CACNA1S Bryony Thompson Added comment: Comment on list classification: Second most common cause of malignant hyperthermia susceptibility after RYR1, but it is still a rare cause.

Added comment: In a study of 103 individuals (63 affected from 34 families, plus 40 sporadic cases) who had either a sentinel event of EHI or MH, or else a positive CHCT and a first degree releative with EHI/MH, and where RYR1 and CACNA1S Sanger sequencing was negative, the following variants in ASPH were identified in unrelated individuals:

- c.161T > C in 2 members of a family with myalgias exacerbated by heat/exercise. One had elevated CK. Both had positive CHCT. An unaffected sibling did not have the variant. 27 hets in gnomad v2 / 17 hets in gnomad v3.
- c.445G>C in a patient with MH, myalgias and muscle cramps worsened by heat and exercise. 4 hets in gnomad v2 / 3 hets in gnomad v3. Non-coding in the MANE transcript.
- c.263A > C in a patient with EHI, diagnosed as MHN by in vitro contracture test. Absent from gnomad but non-coding in the MANE transcript.
- c.605A > G in a patient with EHI, diagnosed as MHN by in vitro contracture test. 223 hets in gnomad v2 / 120 hets in gnomad v3; no homs. Non-coding in the MANE transcript.

A zebrafish model and cell line functional studies supported pathogenicity of the c.161T > C and c.263A > C variants.
