Tubulinopathies affect multiple processes in cortical development, and cause heterogeneous MCDs. Boxes represent the expression, functions, and MCDs associated with TUBA1A, TUBA8, TUBB2A, TUBB2B, TUBB3, TUBB4A, TUBB5, and TUBG1. Abbreviations: CFEOM3: congenital fibrosis of extraocular muscles type 3; CP: cortical plate; H-ABC: hypomyelination with atrophy of the basal ganglia and cerebellum; IZ: intermediate zone; LIS: lissencephaly; LIS-CH: lissencephaly with cerebellar hypoplasia; MIC: congenital microcephaly; MLIS: microlissencephaly; MTOCs: microtubule organizing centers; MZ: marginal zone (Cajal-Retzius neurons in yellow); PAC: pachygyria; PMG: polymicrogyria; PMG-ONH: polymicrogyria with optic nerve hypoplasia; SBH: subcortical band heterotopia; SGP: simplified gyral pattern; SVZ: subventricular zone; VZ: ventricular zone.
