A family member who has a partial HLA (Human Leukocyte Antigen) match may be an acceptable donor for a Bone Marrow Transplant, particularly if a fully matched unrelated donor is not available. While a fully matched donor is preferred to reduce problems and graft failure, a partial match from a family member can still be considered if the HLA match is close enough. The decision on the donor will be based on the patients individual condition and the medical team's recommendations.
