Summaries for Heterotaxy, Visceral, 1, X-Linked

UniProtKB/Swiss-Prot : 71 Congenital heart defects, multiple types, 1, X-linked: A disorder characterized by congenital developmental abnormalities involving structures of the heart. Common defects include transposition of the great arteries, aortic stenosis, atrial septal defect, ventricular septal defect, pulmonic stenosis, and patent ductus arteriosus. The etiology of CHTD is complex, with contributions from environmental exposure, chromosomal abnormalities, and gene defects. Some patients with CHTD also have cardiac arrhythmias, which may be due to the anatomic defect itself or to surgical interventions. Heterotaxy, visceral, 1, X-linked: A form of visceral heterotaxy, a complex disorder due to disruption of the normal left-right asymmetry of the thoracoabdominal organs. Visceral heterotaxy or situs ambiguus results in randomization of the placement of visceral organs, including the heart, lungs, liver, spleen, and stomach. The organs are oriented randomly with respect to the left-right axis and with respect to one another. It can been associated with variety of congenital defects including cardiac malformations.

MalaCards based summary : Heterotaxy, Visceral, 1, X-Linked, also known as congenital heart defects, multiple types, 1, x-linked, is related to heterotaxy and cardiac anomalies-heterotaxy syndrome, and has symptoms including failure to thrive, hypertelorism and cardiomegaly. An important gene associated with Heterotaxy, Visceral, 1, X-Linked is ZIC3 (Zic Family Member 3). Affiliated tissues include heart, spleen and lung.

NIH Rare Diseases : 50 x-linked visceral heterotaxy type 1 is a very rare form of heterotaxy that has only been reported in a few families. heterotaxy is the right/left transposition of thoracic and/or abdominal organs. this condition is caused by mutations in the zic3 gene, is inherited in an x-linked recessive fashion, and is usually seen in males. physical features include heart abnormalities such as dextrocardia, transposition of great vessels, ventricular septal defect, patent ductus arteriosus, pulmonic stenosis; situs inversus, and missing (asplenia) and/or extra spleens (polysplenia). affected individuals can also experience abnormalities in the development of the midline of the body, which can cause holoprosencephaly , myelomeningocele, urological anomalies, widely spaced eyes (hypertelorism), cleft palate, and abnormalities of the sacral spine and anus. heterotaxia with recurrent respiratory infections are called primary ciliary dyskinesia. last updated: 11/9/2011
