Genetic Analysis of Hirschsprung Disease
NYU Langone Health
Summary
Hirschsprung disease is a genetic condition caused by lack of nerve cells in varying lengths of the intestines. This study will investigate the complex genetic basis of the disease, which involves multiple interacting genetic factors.
Description
Hirschsprung disease (HSCR) is a birth defect resulting from the absence of nerve (ganglion) cells in the gastrointestinal tract. Hirschsprung disease has a population incidence of 1/5000 live births and most often occurs as an isolated condition. However, approximately 30% of HSCR cases are associated with other birth defects such as Down syndrome, deafness, hypopigmentation, and congenital central hypoventilation syndrome. Hirschsprung disease is a genetic condition with autosomal dominant, autosomal recessive, and multigenic patterns of inheritance described. Dr. Aravinda Chakravarti's lab…

Blood, saliva, or DNA samples are requested from all study participants. The blood or saliva samples are used to isolate DNA in all participants. Blood samples are also used to establish cell lines in some participants.
