A polymorphic microsatellite marker in the human p55 TNF receptor, CD120a

Genes Immun. 2000 Feb;1(3):228-30. doi: 10.1038/sj.gene.6363663.


We provide characterization of a highly polymorphic dinucleotide repeat in the human TNF-receptor 1 gene (TNFR1, TNFRp55, CD120a). We have observed 11 alleles at this locus in individuals from the West of Scotland. In a panel of healthy, unrelated individuals from the West of Scotland (n = 143), the overall heterozygosity was 68%, indicating the potential usefulness of these markers in immunogenetic studies.
