Summaries for Joubert Syndrome 33

UniProtKB/Swiss-Prot : 75 Joubert syndrome 33: A form of Joubert syndrome, a disorder presenting with cerebellar ataxia, oculomotor apraxia, hypotonia, neonatal breathing abnormalities and psychomotor delay. Neuroradiologically, it is characterized by cerebellar vermian hypoplasia/aplasia, thickened and reoriented superior cerebellar peduncles, and an abnormally large interpeduncular fossa, giving the appearance of a molar tooth on transaxial slices (molar tooth sign). Additional variable features include retinal dystrophy, renal disease, liver fibrosis, and polydactyly. JBTS33 inheritance is autosomal recessive.

MalaCards based summary : Joubert Syndrome 33, is also known as jbts33. An important gene associated with Joubert Syndrome 33 is PIBF1 (Progesterone Immunomodulatory Binding Factor 1). Affiliated tissues include liver, brain and kidney, and related phenotypes are ataxia and global developmental delay

OMIM : 57 Joubert syndrome represents a classic ciliopathy characterized by hypotonia, ataxia, cognitive impairment, and a distinctive brain malformation, the 'molar tooth sign.' In addition, retinal dystrophy, cystic kidney disease, liver fibrosis, and polydactyly occur in a subset of patients (summary by Wheway et al., 2015). For a discussion of genetic heterogeneity of Joubert syndrome, see JBTS1 (213300). (617767)
