Research
Below is a list of studies we are actively participating in:
- Hirschsprung's Disease Research Collaborative - A multi-institutional study investigating the genetics of Hirschsprung’s disease.
- Primary Children’s Hospital Colorectal Center Biobank - Tissue collection of patients with anorectal malformations and Hirschsprung’s disease for future genetic investigation.
- Colorectal Center Patient Registry - Patients with anorectal malformations, Hirschsprung’s, spina bifida, and idiopathic constipation. Collect surgical/patient data and long-term functional outcomes.
- Quality of Life Study - Patients with anorectal malformations, Hirschsprung’s, spina bifida, and idiopathic constipation.
- Utah Genome Project Partnership Grants Program – The genetic basis of Hirschsprung’s disease: identification of genetic interactions that explain the variable phenotype.
- Utah Population Database - A population-based study of the familial incidence of Anorectal Malformations and Hirschsprung’s disease. Describe incidence in a large population. Identify high risk families for genetic investigation.
