Abstract
A large four-generation family with Noonan syndrome (NS) and neurofibr omatosis-type 1 (NF1) was studied for clinical association between the two diseases and for linkage analysis with polymorphic DNA markers of the NF1 region in 17q11.2. Nonrandom segregation between NS and NF1 p henotypes was observed. Neurofibromatosis was tightly linked to NF1 ma rkers, whereas Noonan syndrome was found not be allelic to NF1. These results suggest that two mutations at two independent but closely link ed loci are the cause of neurofibromatosis-Noonan syndrome (NF-NS) ass ociation in this family. (C) 1996 Wiley-Liss, Inc.
