Asbestos and erionite fibres can induce mutations in human lymphocytes that result in loss of heterozygosity.

Abstract excerpt

Although asbestos and erionite are proven human carcinogens, most studies have concluded that these fibres are not mutagenic to mammalian cells in vitro. We have studied the potential of these fibres and chrysotile fibres to induce mutations in human peripheral lymphocytes, using a mutation assay that measures mutation at the autosomal HLA-A locus. Exposure of lymphocytes in culture to 400 micrograms/ml of...
