Historically, diagnosis was primarily via postnatal imaging.

The most common prenatal imaging findings were cerebral ventriculomegaly (15\/19), cerebellar hypoplasia (13\/19), absence of the cavum septum pellucidum (6\/19), abnormalities of the corpus callosum (6\/19), and microcephaly (3\/19). Fetal MRI identified additional central nervous system features that were not appreciated on neurosonogram in eight cases. Single gene variants were reported in TUBA1A (13), TUBB (1), TUBB2A (1), TUBB2B (2), and TUBB3 (2).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The presence of ventriculomegaly with cerebellar abnormalities in conjunction with additional prenatal neurosonographic findings warrants additional evaluation for a tubulinopathy. Conclusive diagnosis can be achieved by molecular sequencing, which may assist in coordination, prognostication, and reproductive planning.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pd.6269","type":"journal-article","created":{"date-parts":[[2022,11,20]],"date-time":"2022-11-20T07:29:20Z","timestamp":1668929360000},"page":"1686-1693","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Prenatal
