Abstract
|
|
|
An unusual blood group inheritance, that is, a phenotype 0 child who was born from AB×A1 parents is reported.
It has been known that cis-AB occurs by the unequal chromosomal crossing-over producing a single chromosome with the genes for A and B enzymes or the structural mutation in A or B genes producing a single abnormal emzyme with the bifunctional
activity
associated with blood group substances. Cis-AB may provide discrepancy between cell and serum typing in ABO blood groups, and make problems in parternity and transfusion.
Recently, authors experienced the cis-A2B3 with 0 child, so we reported with brief review of literatures.
