Inherited Bone Marrow Failure Syndromes (IBMFS) are a group of rare genetic disorders in which the bone marrow cannot produce sufficient blood cells. They may affect red blood cells, white blood cells, platelets, or all three blood cell lines. These conditions often become apparent during childhood, although some cases are diagnosed later in life.

Common examples include Fanconi anaemia, Diamond-Blackfan anaemia, Shwachman-Diamond syndrome, and dyskeratosis congenita. Symptoms vary according to the affected blood cells and may include persistent fatigue, frequent infections, easy bruising, bleeding, pallor, or poor growth. Some syndromes are also associated with distinctive physical abnormalities or problems involving other organs.

Diagnosis usually involves a detailed medical and family history, complete blood counts, bone marrow examination, chromosome or genetic testing, and other specialised investigations. Identifying the underlying genetic cause can help confirm the diagnosis and guide family counselling.

Treatment depends on the specific syndrome and its severity. Supportive care may include blood transfusions, infection management, and medicines that stimulate blood cell production. Haematopoietic stem cell transplantation can provide a potentially curative treatment for selected patients with severe bone marrow failure. Because several IBMFS increase the risk of certain cancers, lifelong monitoring and coordinated specialist care are important. Genetic counselling may also help affected individuals and families understand inheritance patterns and reproductive options.
