TUBB2B encodes a {beta}-tubulin isotype essential for neuronal proliferation, migration, and organization during brain development. Pathogenic heterozygous variants in TUBB2B have been associated with a range of neurodevelopmental disorders, with phenotypes including polymicrogyria and corpus callosum abnormalities. However, the phenotypic spectrum remains heterogeneous, likely influenced by variant-specific effects on microtubule formation and stability, an area that warrants further investigat...
