Summaries for Opitz Gbbb Syndrome, Type Ii

OMIM : 57 Features of the Opitz GBBB syndrome include hypertelorism or telecanthus; laryngotracheoesophageal cleft; clefts of lip, palate, and uvula; swallowing difficulty and hoarse cry; genitourinary defects, especially hypospadias in males and splayed labia majora in females; mental retardation; developmental delay; and congenital heart defects. The Opitz GBBB syndrome was earlier thought to be 2 separate X-linked syndromes called the G syndrome and the BBB syndrome; both were listed in the X-linked catalog as recently as the seventh edition of MIM (1986). The Opitz GBBB syndrome is genetically heterogeneous, with both autosomal dominant and X-linked (300000) forms. Robin et al. (1996) compared the phenotypic features of the X-linked and autosomal forms. They found that anteverted nares and posterior pharyngeal cleft were seen only in the X-linked form. However, all other manifestations of the syndrome, such as hypertelorism, swallowing difficulties, hypospadias, and developmental delay, were seen in both forms. (145410)

MalaCards based summary : Opitz Gbbb Syndrome, Type Ii, also known as opitz-frias syndrome, is related to opitz-gbbb syndrome and opitz gbbb syndrome, type i. An important gene associated with Opitz Gbbb Syndrome, Type Ii is SPECC1L (Sperm Antigen With Calponin Homology And Coiled-Coil Domains 1 Like). The drugs Docetaxel and Prednisone have been mentioned in the context of this disorder. Affiliated tissues include heart, kidney and eye, and related phenotypes are hypertelorism and agenesis of corpus callosum

UniProtKB/Swiss-Prot : 75 Opitz GBBB syndrome 2: A form of Opitz GBBB syndrome, a congenital midline malformation syndrome characterized by hypertelorism, genital-urinary defects such as hypospadias in males and splayed labia in females, cleft lip/palate, laryngotracheoesophageal abnormalities, imperforate anus, developmental delay and congenital heart defects.
