Congenital absence of ganglia in the colon. Heritability varies by segment length. RET mutations are present in ~50% of familial cases.
How Genetic Is Hirschsprung Disease?
Hirschsprung Disease involves complex interactions between multiple genes and environmental factors. Heritability estimates range up to 80%, though no single gene determines outcome on its own.
Key genes associated with Hirschsprung Disease: RET EDNRB GDNF. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Hirschsprung Disease?
Family history can be informative for Hirschsprung Disease, but its predictive power is limited because many genes — each with small effects — combine with environmental influences. A family history of the condition may prompt earlier or more frequent screening.
Frequently Asked Questions
Is Hirschsprung Disease genetic?
Multiple genes and environmental factors interact to influence risk. Studies suggest heritability of approximately 80%. Key genes involved include RET EDNRB GDNF.
Can a DNA test reveal my risk of Hirschsprung Disease?
Genetic testing can identify relevant variants, though Hirschsprung Disease risk is influenced by many factors. Talk to your doctor about appropriate testing.
Does family history matter for Hirschsprung Disease?
Family history can be informative for Hirschsprung Disease, but its predictive power is limited because many genes with small individual effects combine with environmental influences.
Is Hirschsprung Disease hereditary, meaning it's passed directly from parent to child?
Hirschsprung Disease follows a polygenic inheritance pattern in cases with a clear genetic cause, though not every case is inherited directly from a parent — some arise from new (de novo) mutations or a combination of genetic and environmental factors.
