PMID: 25719457 - 0/15 heterozygous carriers report any myopathy phenotype. Majority had porencephaly or periventricular leukoencephalopathy.

PMID: 30315939 - two patients with schizencephaly and/or polymicrogyria. Authors specifically noted myopathy was not observed in any patient, one was reported to have normal CK levels.

Both LOF and dominant negative are suggested mechanisms for this gene.
