Description:
Help
Study uses various methods for further characterization of known loci associated with the disease and discovery of new susceptibility and modifier loci. Laboratory accepts samples from all individuals with Hirschsprung and their families, including: syndromic or non-syndromic, all segment lengths, and isolated case or multiple family members affected.

Test Comments:
Help
Samples received in the laboratory are stored for various genomic studies of Hirschsprung disease. No specific test or set of tests will be completed on every sample. Testing completed on individual samples will vary based on current and future funded research aims, but will be consistent with study consent.
The laboratory is not CLIA certified and individual results are not directly returned to study participants or their healthcare providers.
