Tubulinopathies are genetic disorders affecting brain development due to mutations in tubulins and microtubule-associated proteins. Recognizing common brain imaging patterns aids in diagnosing these complex malformations.

Area of Science:

  • Neuroscience
  • Genetics
  • Radiology

Background:

  • Tubulinopathies are a class of recently identified genetic disorders.
  • These conditions arise from mutations affecting tubulins and microtubule-associated proteins, crucial components of the cytoskeleton.
  • Understanding cytoskeletal function is key to interpreting neuroimaging in these patients.

Purpose of the Study:

  • To elucidate the characteristic neuroimaging findings in tubulinopathies.
  • To correlate specific imaging patterns with underlying genetic causes.
  • To highlight the utility of recognizing imaging phenotypes in guiding genetic diagnosis.

Main Methods:

  • Review of neuroimaging findings in patients with confirmed tubulinopathies.
  • Correlation of imaging features with genetic mutation data.

  • Analysis of the prevalence of specific morphological patterns.

    • Main Results:

    • Consistent imaging patterns observed in tubulinopathies include dysmorphic basal ganglia (hallmark, 75% of cases), callosal dysgenesis, cerebellar hypoplasia/dysplasia, and cortical malformations like lissencephaly.
    • Dysmorphic basal ganglia represent a highly prevalent feature.

    Conclusions:

    • Recognizing common neuroimaging phenotypes associated with tubulinopathies is crucial.
    • Identifying these patterns can significantly aid in directing the genetic workup for patients presenting with brain malformations.
    • This approach facilitates earlier and more accurate diagnosis.
