Gene products mutated in the inherited bone marrow failure syndromes dyskeratosis congenita (DC), cartilage-hair hypoplasia (CHH), Diamond-Blackfan anemia (DBA), and Shwachman-Diamond syndrome (SDS) are all predicted to be involved in different aspects of ribosome synthesis.
These findings link Shwachman-Diamond syndrome to other bone marrow failure syndromes with defects in nucleolus-associated processes, including Diamond-Blackfan anemia, cartilage-hair hypoplasia, and dyskeratosis congenita.
