title: A highly polymorphic CA repeat marker at the human tumor necrosis factor alpha (TNFA alpha) locus.
abstract: Tumor necrosis factor alpha (TNF alpha) in activated monocytes exerts cytotoxic activity and has a variety of other biological effects. We isolated a polymorphic dinucleotide (CA) repeat sequence from a genomic clone containing the gene located at 6p21.3. High heterozygosity (0.80) makes this polymorphism a useful marker in the genetic study of disorders affecting immunological response and cell differentiation.
