Abstract
- Uptake of H-thymidine and its incorporation into DNA was studied in fibroblastic cell lines derived from normal individuals, patients with Fanconi anemia, and those heterozygous for this genetic trait. Uptake and incorporation for the normal cells were about five and seven times higher, respectively, than for Fanconi anemia fibroblasts; mean values for heterozygotes were intermediate. This effect was dependent on the duration of cell exposure to H-thymidine and was not observed with other labeled compounds. Thus, a genetically-determined metabolic defect may exist in Fanconi anemia patients which can be readily studied at the cellular level. This finding may be relevant to the observed clinical, cytogenetic, biochemical, and biologic properties related to expression of the Fanconi anemia gene. [ABSTRACT FROM AUTHOR]
