AFM (afamin)

Gene

• Entrez ID: 173
• Gene name: Afamin
• Gene symbol: AFM
• Synonyms (NCBI Gene): ALB2, ALBA, ALF
• Chromosome: 4
• Chromosome location: 4q13.3
• Summary: This gene is a member of the albumin gene family, which is comprised of four genes that localize to chromosome 4 in a tandem arrangement. These four genes encode structurally-related serum transport proteins that are known to be evolutionarily related. Th
