</div>
<span class="mim-text-font">
<p>Joubert syndrome-24 (JBTS24) is an autosomal recessive ciliopathy characterized by delayed psychomotor development associated with cerebellar hypoplasia manifest as the molar tooth sign on brain imaging. Additional variable features include hypotonia, abnormal eye movements, and postaxial polydactyly (summary by Huppke et al., 2015). </p><p>For a phenotypic description and a discussion of genetic heterogeneity of Joubert syndrome, see 213300.</p>

<strong>Clinical Features</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Sang et al. (2011) reported 7 patients from 4 unrelated families with Joubert syndrome. Features included cerebellar vermis aplasia, the molar tooth sign on brain imaging, hypotonia, and delayed psychomotor development. More variable features included nystagmus, talipes equinovarus, and spasticity. None of the patients had renal abnormalities. </p><p>Huppke et al. (2015) reported a 7.5-year-old Turkish boy, born of consanguineous parents, with a neurodevelopmental disorder consistent with Joubert syndrome. At birth, the patient was noted to have postaxial hexadactyly of all 4 extremities, but no other dysmorphic features. He had hypotonia and severely delayed psychomotor development with inability to speak more than 2 words. He also had nystagmus and hyperopia. Brain MRI showed polymicrogyria, pachygyria, cerebellar hypoplasia with the molar tooth sign, and myelination defects. He learned to walk at age 7 years, but showed spasticity, hyperreflexia, ataxia, and dysmetria. Two previous pregnancies of the parents ended in early abortions within the first trimester, and a subsequent pregnancy was terminated after brain and digital anomalies were detected on prenatal ultrasound. </p><p>In a comprehensive study of 279 patients from 232 unrelated families with Joubert syndrome in whom a genetic basis was determined by molecular analysis of 27 candidate genes, Bachmann-Gagescu et al. (2015) found a significant association between mutations in the TCTN2 gene and encephalocele (odds ratio (OR) of 13.6) and polydactyly (OR of 18.7). </p>
