چکیده

Three chromosome 19 markers known to be linked to myotonic dystrophy have been studied in nine families with peripheral neurofibromatosis (Von Recklinghausen's disease). Clear evidence against linkage has been found for all three markers, excluding the peripheral neurofibromatosis gene from the myotonic dystrophy region of chromosome 19. Previous reports of co-inheritance of the two disorders in families cannot therefore be explained on the basis of close genetic linkage between the loci.

Linkage analysis of neurofibromatosis (von Recklinghausen disease).

Linkage analysis of 28 genetic markers was undertaken in 108 subjects from 11 families with well-documented, classic, peripheral neurofibromatosis. Fifty-four persons were affected in one four-generation family, seven three-generation families, and three two-generation families. Lod scores were calculated using the standard LIPED programme for 49 combinations of theta male and theta female from...

Genetic linkage of von Recklinghausen neurofibromatosis to the nerve growth factor receptor gene.

von Recklinghausen neurofibromatosis (VRNF) is one of the most common inherited disorders affecting the human nervous system. VRNF is transmitted as an autosomal dominant defect with high penetrance but variable expressivity. The disorder is characterized clinically by hyperpigmented patches of skin (café au lait macules, axillary freckles) and by multiple tumors of peripheral nerve, spinal ner...

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

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: a linkage study of candidate and random marker genes.

Genotyping, using plasma proteins or DNA polymorphisms or both, was carried out on 30 families selected through probands with Von Recklinghausen disease. The data provide additional evidence for the exclusion of loci on chromosomes 3 and 5, and chromosome arms 1q, 2p, 4p, 4q, 6q, 7p, 9q, 11p, 11q, and 14q. There was no evidence for genetic heterogeneity at D1S1 (DNF15S2) on chromosome arm 3p, u...

Linkage studies with chromosome 17 DNA markers in 45 neurofibromatosis 1 families.

A locus for von Recklinghausen neurofibromatosis (NF1) has recently been mapped near the chromosome 17 centromere. We have extended these linkage studies by genotyping 45 NF1 families with three DNA probes known to be linked to the chromosome 17 centromeric region. Of 34 families informative for NF1 and at least one of the three probes, 28 families show no recombinants with the disease gene. Th...
