Genes affected

SAT2 (HGNC:23160): (spermidine/spermine N1-acetyltransferase family member 2) Enables diamine N-acetyltransferase activity and identical protein binding activity. Involved in polyamine metabolic process. Located in extracellular exosome. [provided by Alliance of Genome Resources, Apr 2022]

SAT2 links:

SHBG (HGNC:10839): (sex hormone binding globulin) This gene encodes a steroid binding protein that was first described as a plasma protein secreted by the liver but is now thought to participate in the regulation of steroid responses. The encoded protein transports androgens and estrogens in the blood, binding each steroid molecule as a dimer formed from identical or nearly identical monomers. Polymorphisms in this gene have been associated with polycystic ovary syndrome and type 2 diabetes mellitus. Alternative splicing results in multiple transcript variants.
