APOA1 (Apolipoprotein A1) is a gene located on chromosome 11q23 that plays a critical role in lipid metabolism and neurodegenerative disease. Mutations in APOA1 are associated with amyloid deposition and Alzheimer's Disease. The gene is catalogued as NCBI Gene ID 350 and OMIM 107680.
APOA1 is the major protein component of HDL cholesterol and plays a key role in lipid transport and A-beta clearance in the brain. It has been studied for its potential protective role in neurodegeneration.
Apoa1 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
