What are the odds of matching HLA types?
The odds of a siblings having identical tissue types are 1 in 4. The odds of matching an unrelated donor are between 1 in 100 and 1 in a million. Currently, only 25% of the National Registry represent the racial minority communities; therefore, the current odds for a minority patient to find a matching unrelated donor may be more close to 1 in a million. This is the reason for the current funding programs geared specifically to drastically increase the number of donors representing the ethnic minority communities.
