G-PROTEIN COUPLED RECEPTOR KINASE-5 POLYMORPHISM

摘要

The present invention is directed to compositions and methods relating to a G-protein coupled receptor kinase-5 polymorphism. The methods include, for example: detecting enhanced desensitization of the beta adrenergic receptor signaling pathway in an individual, assessing partial protection against heart failure progression in an individual, and assessing an individual's response to beta-blocker therapy. The compositions include polynucleotides or fragments thereof of a nucleotide sequence encoding for a G-protein receptor kinase-5 molecule with a thymine at amino acid position 122 and oligonucleotide primers that hybridize thereto.
