How common is X-linked agammaglobulinemia?
Approximately 1 in 200,000 newborns has X-linked agammaglobulinemia (XLA). Because of the way it is inherited, almost all people with XLA are male. Females who inherit the genetic change that causes XLA are carriers, but almost always unaffected. People from any racial or ethnic group can have XLA.
