GATA2 deficiency syndrome

GATA2 deficiency is a genetic syndrome affecting blood-forming and immune cells. It can cause unusual infections, low blood counts and a predisposition to myelodysplastic neoplasms or acute myeloid leukemia; some people also have lymphatic or lung problems.

Other names and abbreviations

GATA2 deficiency · MonoMAC · DCML deficiency · MonoMAC syndrome · Emberger syndrome · GATA2 haploinsufficiency

Where transplant fits

Allogeneic transplantation can treat serious blood and immune manifestations. Suitable related or unrelated donors may be used. Relatives must be tested for the familial GATA2 variant before being considered as donors.

Treatment depends on the exact diagnosis, disease stage, prior treatment and the person’s health. These categories are not estimates of donor demand.

Treatment at a glance

Who it affects
Manifestations may appear in childhood or adulthood, and some variant carriers remain without symptoms for years.
Other treatment options
Surveillance and infection-directed care are important. Transplant timing considers infections, marrow changes and organ function, rather than the genetic result alone.
Cells used for transplantation
When transplantation is appropriate, the graft contains blood-forming stem cells from a suitable donor. Bone marrow, peripheral blood or cord blood may be selected according to the condition and transplant protocol.

Why the details matter

Penetrance and pace of disease vary. Optimal preemptive timing is not a single universal rule, and transplant may not correct all non-blood manifestations.

Questions to bring to your care team

What is the exact diagnosis or subtype? What is the goal of each treatment option? If transplant is being considered, why does it fit this situation, which cells would be used and what are the alternatives?

Understanding can become action.

Some patients need a blood stem cell donor. Others receive different treatment. Wherever your interest began, you can help JBF reach more people who may be able to donate.
