3 Single-strand conformation polymorphism (SSCP) analysis and subsequent DNA sequencing revealed four novel missense mutations (R24C, E161K, P597S, G618E) and a novel 1-bp deletion (5888delG). Login to comment
46 The P597S (1789C4T) mutation was analyzed using AlwI, which cuts the normal PCR product of exon 13 (280 nts) into fragments of 100, 90, 60, and 30 nts and the mutant PCR product into fragments of 160, 90, and 30 nts. Login to comment
55 Likewise, the 2588C and 2828A variants are presumed to be located in the same allele since the 2588C allele in previous studies was always found together with 2828A (see Discussion).33,49 Next, we employed SSCP analysis and DNA sequencing in patients with one ABCA4 mutation and identified five novel ABCA4 mutations that were not present on the microarray, that is, R24C, E161K, P597S, G618E, and 5888delG.
