In this issue of the Journal appears a remarkable collection of 11 papers from the United States and Europe describing by far the most detailed linkage and physical mapping of the von Recklinghausen neurofibromatosis gene (NF1) undertaken to date (Diehl et al. 1989; Fain et al. 1989; Fountain et al. 1989; Kittur et al. 1989; Ledbetter et al. 1989; Mathew et al. 1989; O'Connell et al. 1989; Seizinger et al. 1989; Stephens et al. 1989; Upadhyaya et al. 1989; Vance et al. 1989). A twelfth paper (Goldgar et al. 1989) describes a multipoint analysis of all of the linkage data, which includes 142 families and over 700 affected individuals. A total of 31 markers in the pericentric region of chromosome 17 were utilized, and 13,838 genotypings were considereda truly impressive collaborative undertaking. NF1 is among the more common dominant disorders of man, with an incidence estimated at 1/3,000 individuals (Crowe et al. 1956; Riccardi 1981; Riccardi and Eichner 1986). The spontaneous mutation rate is quite high, with 30%-50% of affected individuals representing new mutations. This leads to a calculated mutation rate of about 1/10,000, which is about 100-fold higher than the usual mutation rate for a single locus. The clinical features of the disorder are startlingly variable, even within the same family, indicating that other events must play a role in the eventual phenotype of the disease. The diagnostic criteria for NFH (Stumpf et al. 1987) include the presence of two or more of the following: (1) six or more caf6-au-lait macules nmore than 15 mm in greatest diameter in postpubertal individuals, or 5 mm in prepubertal individuals; (2) two or more neu-
