What is Mutational analysis of the ABCC6 gene and the proximal ABCC6 gene promoter in German patients with pseudoxanthoma elasticum (PXE) about?
Pseudoxanthoma elasticum (PXE) is a genetic disorder characterized by calcification of elastic fibers in dermal, ocular, and cardiovascular tissues. Recently, ABCC6 mutations were identified as causing PXE. In this follow-up study we report the investigation of 61German PXE patients from 53 families, hitherto the largest cohort of German PXE patients screened for the complete ABCC6 gene. In addition, we characterized the proximal ABCC6 promoter of PXE patients according to mutation. In this study we identified 32 disease-causing ABCC6 variants, which had been described previously by us and others, and 10 novel mutations (eight missense mutations and two splice site alterations). The mutation detection rate among index patients was 87.7%. Frequent alterations were the PXE-mutations p.R1141X, Ex23,\_Ex29del, and c.2787+1G>T. In the ABCC6 promoter we found the polymorphisms c.-127C>T, c.-132C>T, and c.-219A>C. The difference in the c.-219A>C frequencies between PXE patients and controls were determined as statistically significant. Interestingly, c.-219A>C is located in a transcriptional activator sequence of the ABCC6 promoter and occurred in a binding site for a transcriptional repr
