Multiple Congenital Anomalies-hypotonia-seizures Syndrome 2; Mcahs2

Description

Multiple congenital anomalies-hypotonia-seizures syndrome-2 is an X-linked recessive neurodevelopmental disorder characterized by dysmorphic features, neonatal hypotonia, myoclonic seizures, and variable congenital anomalies involving the central nervous, cardiac, and urinary systems. Some affected individuals die in infancy (summary by Johnston et al., 2012). The phenotype shows clinical variability with regard to severity and extraneurologic features. However, most patients present in infancy with early-onset epileptic encephalopathy associated with developmental arrest and subsequent severe neurologic disability (summary by Belet et al., 2014, Kato et al., 2014). The disorder is caused by a defect in glycosylphosphatidylinositol (GPI) biosynthesis.For a discussion of genetic heterogeneity of MCAHS, see MCAHS1 (OMIM ); for a discussion of genetic heterogeneity of EIEE, see {308350}; and for a discussion of genetic heterogeneity of GPI biosynthesis defects, see GPIBD1 (OMIM ).
