### input:
Hi, I recently learned my Father was Rh Positive and my Mother is Rh Negative . I was born in 1957 - the second of six children. I know sometime in the 60 s any possible problems were eliminated. So I m wondering what types of health problems / risks may I expect in this regard? Is there a known gene mutation that I should know about, so I can share that with a doctor? Thank you. Clara

Hello Clara, Thanks for posting, If you and your siblings did not develop any complications at birth due to mother and fetus incompatibility then you have nothing to worry about now.  Hemolytic disease of the newborn (the condition is known medically as erythroblastosis fetal is) occurs when there is an incompatibility between the blood types of the mother and the fetus/baby. There is also potential incompatibility if the mother is Rh negative and the father is positive. Now since you are lady, what you need to know now is your own blood type to be able to determine if you will require additional medical care when you are pregnant to protect the fetus (from incompatibility). The Rh factor genetic information is also inherited from our parents, but it is inherited independently of the AGO blood type alleles. There are 2 different alleles for the Rh factor known as Rh+ and Rh-. Now, if your father is Rh+ and mother Rh- it means you will likely inherit an Rh+ antigen (your genotype will be Rh+/Rh-= the two alleles but the Rh+ will be the dominant). So I do suggest, you quit being worried and know for sure that you will have no major health risk when it comes to your blood type. Do however get tested (blood groups) just to be sure. Hope this helps
