We have developed a simple rapid DNA screening test that allows us simultaneously to analyze seven CF mutations (delta F508, R347P, S549N, G551D, R553X, R334W, 444delA) that together account for about 60% of all CF mutations in the Italian population. It consists of three steps: multiplex polymerase

โฆ Synopsis
Deletions are the most common molecular defect in steroid sulfatase (STS) deficiency. We describe the application of multiplex DNA amplification, by polymerase chain reaction, for deletion screening in patients with STS deficiency (STS-PCR). Genomic DNA from 38 unrelated patients was amplified using two sets of primers, corresponding to the 5' and the 3' ends of the STS gene. The analysis of the amplified products was always consistent with the results obtained by Southern analysis. This method represents a sensitive fast non-radioactive test for detecting STS gene deletions.
