Coloboma, Congenital Heart Disease, Ichthyosiform Dermatosis, Mental Retardation, And Ear Anomalies Syndrome; Chime

Description

Zunich neuroectodermal syndrome is an extremely rare autosomal recessive multisystem disorder clinically characterized by colobomas, congenital heart defects, migratory ichthyosiform dermatosis, mental retardation, and ear anomalies (CHIME). Other clinical features include distinctive facial features, abnormal growth, genitourinary abnormalities, seizures, and feeding difficulties (summary by Ng et al., 2012). The disorder is caused by a defect in glycosylphosphatidylinositol (GPI) biosynthesis.For a discussion of genetic heterogeneity of GPI biosynthesis defects, see GPIBD1 (OMIM ).
