Genomic regions of SCNN1B investigated for methylation analysis in CFBE and CF primary bronchial epithelial cells. The first zone investigated, the pre-island, covers the region from -673 to -392, contains 56 cytosines and is located upstream to the CpG island. The second zone studied, spans the CpG island, covers the region from − 370 to + 372, contains 236 cytosines and includes the exon 1 and the TSS
