Increased frequency of complement C4 'null' alleles in recurrent spontaneous abortions.

Human reproduction (Oxford, England) - 1 Nov 1991

Abstract excerpt

Typings for major histocompatibility antigens HLA A, B, C and DR and for complement C4A, C4B and factor B were performed for 59 Finnish couples experiencing at least three consecutive recurrent spontaneous abortions (RSA). Forty-one of them were primary abortion (PA) couples with no children and 18 were secondary abortion (SA) couples who had one or two children before abortions. HLA sharing in A and B loci was...
