PG - 428-32 AB - Considering the prevalence of truncating mutations in the tuberous sclerosis (TSC) hamartin gene (TSC1), we devised a protein truncation test (PTT) to analyze the full length coding sequence of TSC1. Studying 12 sporadic cases and three familial forms by a combination of PTT and single-strand conformation polymorphism analysis (SSCA), we found 5/15 mutations while PTT alone detected 4/15 truncating mutations, two of which escaped SSCA analysis. SSCA alone picked up one missense mutation and two mutations also detected by PTT. Interestingly, a TSC1 mutation was identified in all three familial forms (3/3) while the rate of mutation detection was lower in sporadic cases (2/12). In conclusion, PTT proves to be a useful technique for the rapid detection of disease-causing mutations in the TSC1 gene. CI - Copyright 1999 Wiley-Liss, Inc.
