Joubert syndrome 39

Summary

Joubert syndrome-39 (JBTS39) is an autosomal recessive neurodevelopmental disorder with variable manifestations. Most affected individuals have developmental delay with poor speech and retinal dystrophy with abnormal eye movements. Brain imaging shows the pathognomonic 'molar tooth sign,' which reflects abnormal cerebellar formation (Van De Weghe et al., 2021). For a discussion of genetic heterogeneity of Joubert syndrome, see JBTS1 (213300). [from OMIM]
