title: Molecular genetic analysis of the von Hippel-Lindau disease (VHL) tumour suppressor gene in gonadal tumours.
abstract: Chromosome 3p allele loss is frequent in ovarian and testicular tumours. The von Hippel-Lindau (VHL) disease tumour suppressor gene maps to chromosome 3p25. Gonadal tumours may occur in patients with VHL disease, so somatic VHL gene mutations might be involved in the pathogenesis of sporadic gonadal tumours. To investigate this hypothesis, we screened 60 gonadal tumours (36 ovarian and 24 testicular) for VHL gene mutations and chromosome 3p allele loss. Although 38% (10/26) of informative ovarian and 54% (7/13) of testicular tumours demonstrated 3p allele loss, no somatic VHL gene mutations were detected in the 60 gonadal tumours analysed. This suggested that chromosome 3p tumour suppressor gene(s) other than VHL are involved in gonadal tumorigenesis.
