Abstract excerpt

The DNA sequences of the polymorphic region (C4d) that belong to the infrequent complement C4 allotypes C4A13 and C4B12 have been obtained. In addition, C4A4 and C4B2 C4d sequences have been completed. C4A13 shows a new combination of amino acids at the following polymorphic positions: Asp1054, P...
