This website provides information on patients with mutations in the SPEG gene, including clinical data, molecular data, management and research options.

The syndrome caused by mutations in the SPEG gene is a multisystem disorder characterized by

congenital hypotonia and weakness (frequently centronuclear myopathy), early-onset dilated cardiomyopathy, respiratory insufficiency and feeding difficulties. Severity ranges from severe neonatal presentations with early cardiac failure to milder, later-onset myopathic phenotypes.

Not all individuals with a mutation in the SPEG gene have these features. The phenotype varies with variant type and location within the gene, and features are variable.

This website was created to share and collect information about clinic, management and research projects to gather more knowledge and provide better treatment of patients with mutations in the SPEG gene.
