Résumé
BACKGROUND: The RET/GDNF signalling pathway plays a crucial role during development of the kidneys and the enteric nervous system. In humans, RET activating mutations cause multiple endocrine neoplasia, whereas inactivating mutations are responsible for Hirschsprung disease. RET mutations have also been reported in fetuses with renal agenesis, based on analysis of a small series of samples. OBJECTIVE AND METHODS: To characterise better the involvement of RET and GDNF in kidney development defects, a series of 105 fetuses with bilateral defects, including renal agenesis, severe hypodysplasia or multicystic dysplastic kidney, was studied. RET and GDNF coding sequences, evolutionary conserved non-coding regions (ECRs) in promoters, 3'UTRs, and RET intron 1 were analysed. Copy number variations at these loci were also investigated. RESULTS: The study identified: (1) a low frequency (
