An NcoI polymorphism in the human complement component 7 (C7) gene.
A novel polymorphic site has been found in the 3' untranslated region (UTR) of the human complement component 7 (C7) gene. The polymorphic site at 14-bp down-stream from the TAG stop codon was either C or A (Nco I-digested), with allele frequencies of 0.660 and 0.340. This NcoI polymorphism would be useful to perform a DNA marker haplotype study in patients with deficiencies of the complement genes, such as C6, C7, C9, which are located closely on chromosome 5p13.
