Keloid disease and hypertrophic scars are dermal tumors that are often familial and typically occur in certain races. Their exact etiology is still unknown. Transforming growth factor beta1 (TGF-beta1) plays a central role in wound healing and fibrosis and has been implicated in the pathogenesis of keloid disease and hypertrophic scar. The aims of this study were to measure the plasma level of TGF-beta1 in patients compared with controls, and to investigate the association of five common single nucleotide polymorphisms in TGF-beta1 with the risk of keloid disease and hypertrophic scar formation. Platelet-poor plasma levels of TGF-beta1 in 60 patients (15 with hypertrophic scar and 45 with keloid disease) and 18 controls were measured using an enzyme-linked immunoabsorbent assay technique. A polymerase chain reaction-restriction fragment length polymorphism method was used for genotyping TGF-beta1 polymorphisms. DNA samples from 133 patients (101 with keloid disease and 32 with hypertrophic scar) and 200 controls were examined. All patients and controls were Caucasians of Northern European extraction. There was no statistically significant difference in TGF-beta1 plasma levels between patients with keloid disease and hypertrophic scar and controls. There was also no statistically significant difference in genotype or allele frequency distributions between patients and controls for codons 10, 25, and 263 and for -509 and -800 single nucleotide polymorphisms of the TGF-beta1 gene. These results suggest that TGF-beta1 plasma levels and common polymorphisms are not associated with a risk of keloid disease and hypertrophic scar formation. This lack of association may be significant in view of the importance attached to the role of TGF-beta1 in dermal scarring. To the authors' knowledge, this is the first report of a case-control association study in keloid disease and hypertrophic scars using any single nucleotide polymorphisms.
