Acoustic neuromas occur either as sporadic solitary tumors in the general population or as inherited bilateral tumors typically in patients with neurofibromatosis type 2. Loss of heterozygosity for markers on the long arm of chromosome 22 has been reported in both instances, and neurofibromatosis ty

Univenitatsklinikum Essen, Federal Republic of Germany Uveal melanoma is the most frequent primary intraocular tumor. The etiology is unknown. Using neutral DNA polymorphisms on chromosomes 2, 3, and 8, we have detected loss of chromosome 3 alleles in 8 of 13 tumors and multiplication of chromosome 8 alleles in 6 of I I tumors. No anomalies at a locus on chromosome 2 were found in I0 of I0 tumors. These results confirm and extend previous cytogenetic findings and suggest that a tumor suppressor gene on chromosome 3 and an oncogene on chromosome 8 may be involved in the formation o r progression of this tumor.

Posterior uveal melanomas have nonrandom alterations affecting chromosomes 3, 6, and 8. Loss of chromosome 3 in uveal melanoma has been shown to act as a predictor of disease-free and overall survival. To confirm the significance of chromosome 3 loss and to extend the observations to include those o
## Abstract Colorectal carcinogenesis is associated with the accumulation of genetic changes involving both dominant oncogenes and tumor suppressor genes. Although at least four different genes have been implicated in the process, the detection of allele loss from other regions of the genome sugges
## Abstract Six posterior uveal melanomas were karyotyped after shortβterm culture. One had a normal chromosome complement; the remaining five had limited chromosome changes. Involvement of chromosomes 1 and 6 was noted in two and four cases, respectively, and three ciliary body tumours demonstrate
Frequent loss of heterozygosity on chromosome 8p in a variety of human malignancies, including head and neck cancers, has suggested the presence of a tumor suppressor gene (or genes) associated with the pathogenesis of these cancers.

## Abstract We present ten cases of posterior uveal melanoma which were karyotyped after shortβterm culture. One tumour had a normal chromosome complement. The remaining nine tumours were cytogenetically abnormal, with chromosomes 3, 6, 8, 11, and 13 most frequently involved. Abnormalities of chrom
