Inherited Bone Marrow Failure Syndromes

Inherited bone marrow failure syndromes (IBMFS) are a group of rare genetic disorders in which the bone marrow cannot produce adequate numbers of healthy blood cells. These conditions often appear during childhood but may also be diagnosed in adolescence or adulthood. Reduced production of red blood cells, white blood cells, and platelets can lead to anaemia, recurrent infections, and abnormal bleeding. Many syndromes are also associated with physical abnormalities, developmental differences, and an increased lifetime risk of leukaemia or other cancers.

Common inherited bone marrow failure syndromes include Fanconi anaemia, Dyskeratosis congenita, Shwachman-Diamond syndrome, Diamond-Blackfan anaemia, and severe congenital neutropenia. Symptoms vary depending on the specific disorder but may include fatigue, pale skin, frequent infections, easy bruising, nosebleeds, poor growth, and congenital abnormalities affecting the skeleton, skin, or internal organs.

Diagnosis involves a complete blood count, bone marrow examination, chromosome breakage studies, genetic testing, and specialised laboratory investigations. Identifying the exact genetic cause helps guide treatment and family counselling.

Management focuses on improving blood cell production, preventing complications, and monitoring for cancer development. Treatment options may include blood transfusions, growth factor therapy, antibiotics, iron management, and haematopoietic stem cell transplantation. Lifelong follow-up with a multidisciplinary healthcare team is essential to optimise health outcomes and quality of life.
