Further exclusion data for the Von Recklinghausen neurofibromatosis gene: a genetic linkage study of 19 polymorphic markers.

Abstract
Linkage analysis on a panel of 15 Von Recklinghausen neurofibromatosis (VRNF) families with 19 polymorphic markers was carried out using the computer programme M-link. Our findings have excluded VRNF from a significant proportion of the genome. Von Recklinghausen neurofibromatosis (VRNF) is one of the commonest autosomal dominant disorders in man with a prevalence of at least 20/100,0001 of the population. The mapping of the VRNF gene will be an important step towards our eventual understanding of the pathogenesis of the disease and a closely linked marker would be immediately applicable in prenatal diagnosis where appropriate.
