ASSOCIATION OF THE <i>C2</i>‐DEFICIENCY GENE (<i>C2</i>*<i>QO</i>) WITH THE <i>C4A*4, C4B*2</i> GENES

Abstract

SUMMARY C4 typing in thirteen homozygous C2‐deficient patients and in a family with heterozygous C2 deficiency showed a strong association of the C2 ‐deficiency gene ( C2*QO ) with the relatively rare C4A* C4B*2 haplotype.
