GLB1‐related disorders are also associated with skeletal deformities (eg, kyphoscoliosis and short stature), which, like in other lysosomal storage diseases, nosologically have been classified as dysostosis multiplex.2, 3 Morquio‐B disease (MBD) (OMIM 253010)4 is a distinct form of GLB1‐related disorder presenting with a specific type of dysostosis multiplex which has been known as Morquio syndrome since its first description by Morquio5 and Brailsford. 6 This evidence concerns the gene GLB1 and lysosomal storage disease with skeletal involvement.
