Abstract
Purpose: In the present study, we tested the hypothesis that microsatellite alterations (MSI) and loss of heterozygosity (LOH) are associated with Peyronie’s disease. To test this hypothesis, we analyzed samples from patients with Peyronie’s for MSI and LOH on chromosomes 3, 8 and 9 using 20 different genetic markers.Materials and Methods: DNA was isolated from the penile fibrotic plaque, amplified using PCR, and analyzed for MSI and LOH on chromosomes 3, 8 and 9 using 20 different polymorphic markers (D3S1228, D3S1298, D3S1560, D3S1745, D3S2396, D3S647, D8S133, D8S255, D8S259, D8S260, D8S262, D8S285, D8S298, D8S507, D8S528, D9S162, D9S171, D9S1747, D9S1748, and D9S273). Only 10 primers (D3S1560, D3S647, D3S1298, D8S262, D8S260, D8S528, D9S171, D9S1747, D9S273 and D9S1748) showed MSI and LOH in Peyronie’s samples. Microsatellite alterations and LOH were analyzed by a PCR-based technique developed in our laboratory.Results: This study demonstrates a high frequency of MSI and LOH in Peyronie’s disease. Four...
