  • Patent number: 11510907
    Abstract: Described herein is a genetic modifier of cystic fibrosis (CF), which may serve as a predictor of the efficacy of a CFTR-directed therapy. SNPs rs7512462 or rs2869027 in non-coding regions of SLC26A9 are shown to correlate with CF lung disease severity in patients having CFTR mutations that leave protein at the cell surface, e.g. gating mutations such as G551D. It is also shown that patient response to Ivacaftor correlates with SLC26A9 genotype. Given the biology of SLC26A9, risk alleles of SLC26A9 should correlate with reduced SLC26A9. SLC26A9 activity (marked by e.g. genotype or expression level) is therefore a predictor of treatment efficacy for any CFTR-directed therapeutic, such as Ivacaftor or Lumacaftor. Associated methods of selecting and treating patients are described, along with related kits, uses, and drug discovery platforms.

It is also shown that patient response to Ivacaftor correlates with SLC26A9 genotype. Given the biology of SLC26A9, risk alleles of LC26A9 should correlate with reduced SLC26A9. SLC26A9 activity (marked by e.g. genotype or expression level) is therefore a predictor of treatment efficacy for any CFTR-directed therapeutic, such as Ivacaftor or Lumacaftor. Associated methods of selecting and treating patients are described, along with related kits, uses, and drug discovery platforms.

  • Patent number: 6844189
    Abstract: The present invention relates generally to the field of human genetics. Specifically, the present invention relates to methods and materials used to isolate and detect a human prostate cancer predisposing gene (HPC2), some alleles of which cause susceptibility to cancer, in particular prostate cancer. More specifically, the present invention relates to germline mutations in the HPC2 gene and their use in the diagnosis of predisposition to prostate cancer. The invention also relates to presymptomatic therapy of individuals who carry deleterious alleles of the HPC2 gene. The invention further relates to somatic mutations in the HPC2 gene in human prostate cancer and their use in the diagnosis and prognosis of human prostate cancer. Additionally, the invention relates to somatic mutations in the HPC2 gene in other human cancers and their use in the diagnosis and prognosis of human cancers.
