Sajid,
I'm sorry to hear about your daughter's aplastic anemia.
You could try contacting the
National Institute of Blood Diseases, the
Aga Khan University Hospital, and the
Pakistan Institute of Medical Sciences to ask for advice. I suggest that you ask who can search the international registries to see if there is a match for your daughter in the registry of
any country, not just in Pakistan.
Pakistan desperately needs a national bone marrow registry and for people to join it. In 2011 there was a "Pakistan Marrow Donor Registry" website at pmdr.org but the website is no longer there, perhaps due to a loss of funding.
Here is a snapshot of what the site looked like in 2011.
I've read that when there is no better choice many doctors in Pakistan give their patients a "haplo" transplant, where a half-matched parent (usually the mother) is the donor.
If you know your daughter's DR type (not just A and B) then you can check for a potential match in the U.S. bone marrow registry using
MatchView.
