In a 21-week-old fetus (UW351-3) with Joubert syndrome-37 (JBTS37; 619185), Latour et al. (2020) identified compound heterozygous missense mutations in the TOGARAM1 gene: a c.1124T-C transition (c.1124T-C, NM_015091.2), resulting in a leu375-to-pro (L375P) substitution at a highly conserved residue in the TOG2 domain, and a c.3931C-T transition, resulting in an arg1311-to-cys (R1311C; 617618.0002) substitution at a highly conserved residue in the TOG3 domain. The mutations, which were found by exome sequencing, were each inherited from an unaffected parent. L375P was present at a low frequency in the gnomAD database (8 of 276,914 alleles), whereas R1311C was not present. Studies of patient cells were not performed, but functional expression studies in transfected TOGARAM1-null RPE cells showed that L375P resulted in longer cilia, whereas R1311C resulted in shorter cilia, compared to controls. L375P abolished the interaction between TOGARAM1 and ARMC9 (617612), whereas R1311C did not influence this interaction.
