Summaries for Warsaw Breakage Syndrome

Genetics Home Reference : 25 Warsaw breakage syndrome is a condition that can cause multiple abnormalities. People with Warsaw breakage syndrome have intellectual disability that varies from mild to severe. They also have impaired growth from birth leading to short stature and a small head size (microcephaly). Affected individuals have distinctive facial features that may include a small forehead, a short nose, a small lower jaw, a flat area between the nose and mouth (philtrum), and prominent cheeks. Other common features include hearing loss caused by nerve damage in the inner ear (sensorineural hearing loss) and heart malformations.

MalaCards based summary : Warsaw Breakage Syndrome, also known as wabs, is related to roberts syndrome and autoimmune disease 3, and has symptoms including high palate, intellectual disability and muscular hypotonia. An important gene associated with Warsaw Breakage Syndrome is DDX11 (DEAD/H-Box Helicase 11). Affiliated tissues include heart and skin.

Disease Ontology : 12 A syndrome mainly characterized by severe growth retardation and microcephaly. It is a new form of cohesinopathy showing defects in sister chromatid cohesion and hypersensitivity to chemicals that induce replication stress, thus combining distinct cytogenetic features seen in Roberts syndrome and Fanconi anemia, respectively. It has material basis in homozygous or compound heterozygous mutation in the DDX11 gene on chromosome 12p11.

UniProtKB/Swiss-Prot : 66 Warsaw breakage syndrome: A syndrome characterized by severe microcephaly, pre- and postnatal growth retardation, facial dysmorphism and abnormal skin pigmentation. Additional features include high arched palate, coloboma of the right optic disk, deafness, ventricular septal defect, toes and fingers abnormalities. At cellular level, drug-induced chromosomal breakage, a feature of Fanconi anemia, and sister chromatid cohesion defects, a feature of Roberts syndrome, coexist.
