S. Distante et al., FAMILIAL ADENOMATOUS POLYPOSIS IN A 5-YEAR-OLD CHILD - A CLINICAL, PATHOLOGICAL, AND MOLECULAR-GENETIC STUDY, Journal of Medical Genetics, 33(2), 1996, pp. 157-160
A girl aged 5 years 8 months presented with rectal bleeding; her fathe
r had had familial adenomatous polyposis (FAP) and a colectomy at the
age of 23. Endoscopy showed extensive polyposis and she had a colectom
y. The proband and her father had the common codon 1309 5 bp deletion
APC mutation. This mutation predisposes to early onset of FAP, and con
sideration needs to be given to having molecular testing of at risk me
mbers of these families done in childhood.
