Evolution of the ABO blood group gene in Japanese macaque.
We determined 5 sequences of Japanese macaque ABO blood group gene exon 7 (ca. 0.5 kb) and 2 sequences for exon 5 and intron 6 (ca. 1.7 kb). We compared those data with published sequences of other Old World monkey species, and the results suggest that alleles A and B were polymorphic in the ancestral species of macaques, and that B type allele evolved independently in macaque and baboon lineages.
متن کاملThe effect of parental ABO blood group on fetal surveillance
Background Several factors may cause infertility and fetal loss. Blood groups antigens seem to be implied in the mechanisms of infertility and fetal loss. Maternal natural antibody can react against father’s blood group antigens on spermatozoa. The effects of parental blood group system on infertility and fetal surveillance perceived by its manifestation in prezygotic (caused infertility) and ...
متن کاملGenetic Sequencing Analysis of A307 Subgroup of ABO Blood Group
BACKGROUND The aim of this study was to investigate the serology and gene sequence characteristics of the A307 subgroup of the ABO blood group. MATERIAL AND METHODS Monoclonal anti-A and anti-B antibodies were used to detect the ABO antigens of a proband whose positive blood type was not consistent with the negative blood type of the ABO blood group. Standard A-, B-, and O-negative typing cells...
متن کاملImmunologic homology of human blood group glycosyltransferases and genetic background of blood group (ABO) determination.
The human blood groups (ABO) are known to be determined by the terminal carbohydrate residues attached to common carbohydrate chains of the red cell surface. Specific transferases, i.e., N-acetylgalactosaminyltransferase (A enzyme) in blood group A persons and galactosyltransferase (B enzyme) in blood group B persons. are responsible for transferring the carbohydrates to the terminal galactose ...
متن کاملABO blood group distribution in serum hepatitis.
A disproportionate excess of blood group O was found in a circumscribed outbreak of serum hepatitis among patients and staff of a haemodialysis unit. The more severe cases were also mostly of group O. This suggests that host factors may be important in the genesis of this disease.
