BTK (Bruton Tyrosine Kinase) is a Protein Coding gene. Diseases associated with BTK include Agammaglobulinemia, X-Linked 1 and Agammaglobulinemia And Isolated Hormone Deficiency. Among its related pathways are RET signaling and Fc-GammaR Pathway.
The preproenkephalin gene, PENK, encodes for the endogenous opiates that modulate pain perception, and are implicated in reward and addiction. (CA) repeats in the 3' flanking sequence of the PENK gene was associated with greater likelihood of opiate dependence in repeated studies.
