Opitz Gbbb Syndrome, Type I; Gbbb1

Description

The Opitz GBBB syndrome is a congenital midline malformation syndrome characterized by hypertelorism, hypospadias, cleft lip/palate, laryngotracheoesophageal abnormalities, imperforate anus, developmental delay, and cardiac defects (So et al., 2005).This disorder was first reported as 2 separate entities, BBB syndrome and G syndrome; subsequent reports of families in which the BBB and G syndromes segregated within a single kindred suggested that they represent a single entity. Genetic HeterogeneitySee also GBBB2 (OMIM ), caused by mutation in the SPECC1L gene (OMIM ) on chromosome 22q11.
