β-Tubulinopathy caused by a mutation of the TUBB2B gene: magnetic resonance imaging findings of the brain



β-Tubulinopathy caused by a mutation of the TUBB2B gene: magnetic resonance imaging findings of the brain



Neuroradiology Journal 2019: 1971400919828142



Patients with mutations in tubulin-related genes usually present with brain malformations, intellectual disability, epilepsy, microcephaly and ocular abnormalities. In these patients the diagnosis can be suggested by neuroimaging findings. We report a 5-year-old patient with characteristic magnetic resonance imaging findings including malformation of cortical development, fused basal ganglia, large head of the caudate nuclei, absent anterior limbs of the internal capsules, corpus callosum dysgenesis and dysplastic cerebellar vermis. Sequencing of the TUBB2B gene confirmed a heterozygous mutation: c. 260C>A (p. Pro87Gln).
