Ms. Fewtrell et al., HIRSCHSPRUNGS-DISEASE ASSOCIATED WITH A DELETION OF CHROMOSOME-10 (Q11.2Q21.2) - A FURTHER LINK WITH THE NEUROCRISTOPATHIES, Journal of Medical Genetics, 31(4), 1994, pp. 325-327
We report a patient with total colonic aganglionosis in association wi
th a deletion of part of the long arm of chromosome 10: (del(10)(q11.2
q21.2)). This deletion includes the ret proto-oncogene, which has rece
ntly been implicated in multiple endocrine neoplasia type 2A (MEN 2A).
The possible links between Hirschsprung's disease and the neurocristo
pathies and the aetiological role of abnormalities of neural crest dev
elopment in these conditions are discussed.
