rare kidney involvement. The phenotype is indistinguishable from that of JBTS2 (608091)
(summary by Lee et al., 2012). For a phenotypic description and a discussion of genetic
heterogeneity of Joubert syndrome, see 213300.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the transmembrane protein 138 gene (TMEM138, 614459.0001);
