Chromosome 17 markers and von Recklinghausen neurofibromatosis: a genetic linkage study in a British population.

A genetic linkage study of the RFLPs identified by nine DNA probes localized to the pericentromeric region and long arm of chromosome 17 has been undertaken in 16 families with von Recklinghausen neurofibromatosis (NF1). Close linkage has been shown with the markers CRI-L946 (D17S36), CRI-L581 (D17S37), p17H8 (D17Z1), and pA10-41 (D17S71). The ERBA1 and COL1A1 loci may also be closely linked, but the data are limited. The results for HOX2 and NGFR suggest only loose linkage with the NF1 gene, while no linkage was found between NF1 and the growth hormone locus. No suggestion of nonallelic heterogeneity of NF1 was found in this study.
