Presentation
Patient B further fits a more typical presentation, with well-controlled epilepsy and mild hypertonia, whereas Patient A’s presentation is much milder without these other features. [bmcmedgenet.biomedcentral.com]
Two of the herein described individuals (i084n, i085n) also presented these features. [ojrd.biomedcentral.com]
Motor and cognitive impairments are present in almost all individuals with a tubulinopathy, most affected individuals have severe-to-profound intellectual disability. [globalgenes.org]
Abnormalities of the midbrain tectum were recorded when present. [ajnr.org]
All three patients presented with seizures in early life. [nature.com]

- Epilepsy
Results We describe two unrelated individuals with mildly simplified gyration and infantile-onset epilepsy, harbouring de novo variants that affect adjacent amino acids in a novel tubulinopathy gene, TUBB2A. [jnnp.bmj.com]
The clinical features of the tubulinopathies include motor and intellectual disabilities and epilepsy. [globalgenes.org]

All but one of the eleven reviewed cases of TUBG1 mutations involved epilepsy, majority of which were refractory and early-onset in nature. [bmcmedgenet.biomedcentral.com]
Clinical symptoms include a global developmental disorder, epilepsy, often primary microcephaly and eye involvement of various degrees. The diagnosis is usually made on the basis of the specific brain malformation findings. [medicover-genetics.com]

We suggest that recognition of this characteristic feature aids in the diagnosis of tubulinopathy, especially when associated with microcephaly. [ajnr.org]
Conclusion This report expands the spectrum of TUBG1 mutation manifestations, suggesting the possibility of less severe phenotypes for patients and families, and influencing genetic counselling strategies. [bmcmedgenet.biomedcentral.com]
