CFTR modifier genes and expressed polypeptides useful in treating cystic fibrosis and methods and products for detecting and/or identifying same

摘要

The discovery that CFTR modifier genes, in particular the Kir4.2 gene, the expressed polypeptide(s), as well as genetic and polypeptide regulators thereof, can be used to treat cystic fibrosis (CF), or at least the conditions that cause CF. Methods and products for detecting and/or identifying CFTR modifier genes, their respective expressed polypeptides, the genetic regulators of such CFTR modifier genes, and the regulators of their respective expressed polypeptides are disclosed. Also disclosed are compositions and methods using these CFTR modifier genes, their respective expressed polypeptides, genetic regulators of these CFTR modifier genes, and/or CFTR modifier polypeptide regulators for the purpose of treating CF, or at least the conditions that cause CF, are disclosed.
