Green List (high evidence)

Variants in this gene are associated with a range of myopathies. However, the newsline myopathy can have mildly raised CK, and central features.

Panel Version: 0.103

Mode of inheritance

Elena Savva (Victorian Clinical Genetics Services)

Green List (high evidence)

No genotype-phenotype correlation (OMIM), but nearly all PTCs have been reported for AR disease

Incomplete penetrance has been described but report is older (none with newer reports) where 2nd hits were potentially missed or variant pathogenicity incorrectly called.
