Frequently Asked Questions

1. What are bone marrow failure syndromes (BMFS)?

BMFS are a group of disorders characterised by insufficient production of blood cells in the bone marrow, leading to anaemia, thrombocytopenia, and other haematological abnormalities.

2. How do genetics and genomics contribute to BMFS?

Genetic mutations, both inherited and somatic, play a critical role in the development of BMFS by disrupting vital cellular processes involved in blood cell production.

3. What are some common types of BMFS?

Aplastic anaemia, Fanconi anaemia, Diamond-Blackfan anaemia, and Shwachman-Diamond syndrome are well-known BMFS, each with distinct genetic underpinnings.

4. What is the significance of understanding the genetic basis of BMFS?

Unravelling the genetic basis of BMFS helps us comprehend disease mechanisms, aids in accurate diagnosis, guides treatment decisions, and opens avenues for targeted therapies.

5. What are some advancements in genomics research related to BMFS?

Techniques like whole-genome and exome sequencing have identified genetic variants linked to BMFS, leading to a deeper understanding of their molecular origins.

6. How do genetic mutations lead to BMFS?

Mutations in specific genes disrupt processes such as DNA repair, telomere maintenance, and ribosome biogenesis, causing abnormal cell development and ultimately resulting in BMFS.
