The disease ranges from mild to severe, and occurs in the second or subsequent pregnancies of Rh-D negative women when the biological father is Rh-D positive. Due to several advances in modern medicine, HDFN due to anti-D is preventable by treating the mother during pregnancy and soon after delivery with an injection of anti-Rh o (D) immune ...
The Lan-negative blood type is inherited in an autosomal recessive manner, being expressed by individuals who are homozygous for nonfunctional alleles of ABCB6. [ 1 ] [ 2 ] Some variant alleles cause a weak positive phenotype, which may be mistaken for a Lan-negative phenotype in serologic testing. [ 2 ]

The false positive rate (FPR) is the proportion of all negatives that still yield positive test outcomes, i.e., the conditional probability of a positive test result given an event that was not present. The false positive rate is equal to the significance level. The specificity of the test is equal to 1 minus the false positive rate.
A Rhc negative mother can become sensitised by red blood cell (RBC) Rhc antigens by her first pregnancy with a Rhc positive fetus. The mother can make IgG anti-Rhc antibodies, which are able to pass through the placenta and enter the fetal circulation. If the fetus is Rhc positive alloimmune hemolysis can occur leading to HDN.
