Multiple congenital anomalies-hypotonia-seizures syndrome
Inherited glycosylphosphatidylinositol deficiencies [DS:H01489]
The Multiple Congenital Anomalies-Hypotonia-Seizures Syndrome (MCAHS) comprises three phenotypes caused by mutations in PIGN, PIGA and PIGT respectively. PIGN and PIGT mutations lead to autosomal recessive disorders whereas PIGA deficiency causes an X-linked lethal disorder. Clinical features are variable dependent on genotypes, often include (neonatal) hypotonia, seizures, various anomalies involving nervous system structural malformations, delayed or lack of psychomotor development, and various congenial organ anomalies.
