Background: Microtubules, polar polymers of αβ-tubulin heterodimers, constitute dynamic cytoskeletal structures implicated in the regulation of axonal activity along with neuronal proliferation and migration. Tubulinopathies, caused by pathogenic variants in genes encoding different isotypes of tubulin, lead to a wide and overlapping range of nervous system malformations and neurodevelopmental disorders. Namely, heterozygous missense and nonsense mu...

Background: Achondroplasia is a genetic disorder that belongs to a large group of skeletal dysplasias that is caused by a missense mutation in the gene encoding FGFR-3 resulting in its constitutive upregulating. This interferes with the receptor's tyrosine kinase domain causing inhibition of cartilage tissue cells and the formation of abnormalities in the bone growth plate leading to defective skeletal development and a disproportionately short stature wi...
