TUBA1A and tubulinopathy: In addition to TUBB3, at least eight tubulins (TUBA1A, TUBB2A, TUBB2B, TUBB, TUBA4A, TUBB4A, and TUBG1) have been reported to be expressed in neurons [25,26,27,28,29,30,31,32,33]; mutations in genes encoding for neuronal tubulin isotypes give rise to a wide class of neurodevelopmental and neurodegenerative disorders known as “tubulinopathies” [34].
