Ribosome biogenesis in skeletal development and the pathogenesis of skeletal disorders

• Ribosome biogenesis is integral to all cell growth and proliferation.
• Disruption of ribosome biogenesis leads to congenital disorders termed ribosomopathies.
• Congenital skeletal anomalies affect approximately 1 in 3000 live births.
• The role of ribosome biogenesis in skeletal development is poorly understood.
• Skeletal function is inextricably linked to the size and shape of individual bones.

The skeleton affords a framework and structural support for vertebrates, while also facilitating movement, protecting vital organs, and providing a reservoir of minerals and cells for immune system and vascular homeostasis. The mechanical and biological functions of the skeleton are inextricably linked to the size and shape of individual bones, the diversity of which is dependent in part upon differential growth and proliferation. Perturbation of bone development, growth and proliferation, can result in congenital skeletal anomalies, which affect approximately 1 in 3000 live births [1]. Ribosome biogenesis is integral to all cell growth and proliferation through its roles in translating mRNAs and building proteins. Disruption of any steps in the process of ribosome biogenesis can lead to congenital disorders termed ribosomopathies. In this review, we discuss the role of ribosome biogenesis in skeletal development and in the pathogenesis of congenital skeletal anomalies.
