Summaries for Opitz-Gbbb Syndrome

NIH Rare Diseases : 50 opitz g/bbb syndrome is an inherited condition that affects several structures along the midline of the body. the most common features are wide-spaced eyes and defects of the larynx, trachea, and/or esophagus causing breathing problems and difficulty swallowing. affected males usually have a urethra opening on the underside of the penis (hypospadias). other features can include mild intellectual disability, cleft lip and/or a cleft palate, heart defects, an obstruction of the anal opening (imperforate anus), agenesis of the corpus callosum, and facial abnormalities. these features may vary, even among members of the same family.there are two forms of opitz g/bbb syndrome, which are distinguished by their genetic causes and patterns of inheritance. the x-linked form is caused by mutations in the mid1 gene. autosomal dominant opitz g/bbb syndrome is caused by a deletion of 22q11.2, and is often referred to as 22q11.2 deletion syndrome. treatment depends on the individual’s specific needs. last updated: 11/14/2016

MalaCards based summary : Opitz-Gbbb Syndrome, also known as opitz g/bbb syndrome, is related to opitz gbbb syndrome, type ii and opitz gbbb syndrome, type i, and has symptoms including hypertelorism, low-set ears and pectus excavatum. An important gene associated with Opitz-Gbbb Syndrome is MID1 (Midline 1), and among its related pathways/superpathways are Valine, leucine and isoleucine degradation and Lysine degradation. Affiliated tissues include eye, heart and trachea.

Disease Ontology : 12 A monogenic disease that is characterized by hypertelorism, hypospadias, and additional midline defects resulting from mutations to the MID1 gene in the X-linked form or from a deletion on chromosome 22q11.2 in the autosomal dominant form.

Genetics Home Reference : 25 Opitz G/BBB syndrome is a genetic condition that causes several abnormalities along the midline of the body. "G/BBB" represents the first letters of the last names of the families first diagnosed with this disorder and "Opitz" is the last name of the doctor who first described the signs and symptoms. There are two forms of Opitz G/BBB syndrome, X-linked Opitz G/BBB syndrome and autosomal dominant Opitz G/BBB syndrome. The two forms are distinguished by their genetic causes and patterns of inheritance. The signs and symptoms of the two forms are generally the same.
