Identification of de novo deletions at the NF1 gene: no preferential paternal origin and phenotypic analysis of patients.

Abstract excerpt

Neurofibromatosis type 1 (NF1) is a common autosomal dominant disorder. To date, a relatively small number of NF1 mutations have been characterized, thus precluding genotype-phenotype correlations. By genotyping 75 NF1 families, we have detected six hemizygous patients (two of whom are members of the same family). The five presumed deletions were confirmed by two quantitative methods of analysis of NF1 copy...
