Type I familial amyloidotic polyneuropathy(FAP) results from the systemic deposition of a plasma transthyretin(TTR) variant with a Val ▶ Met change at position 30. In an attempt to establish a model of this disease, we generated transgenic mice producing the variant TIR. A DNA fragment containing the mouse metallothionein-I promoter fused to the structural gene coding for the human TTR variant was microinjected into fertilized mouse eggs. Among 72 mice that developed from these eggs, ten carried the fusion gene and three of these showed significant concentrations of the variant TTR in their serum. These mice may be useful in elucidating the pathogenesis of FAP and in establishing a therapy for this intractable disorder.
