In a 16-year-old boy (UW360-3) with Joubert syndrome-37 (JBTS37; 619185) Latour et al. (2020) identified compound heterozygous mutations in the TOGARAM1 gene: a c.1084C-T transition (c.1084C-T, NM_015091.2), resulting in a gln362-to-ter (Q362X) substitution in the TOG2 domain, and a 12-kb intragenic deletion, resulting in the deletion of exons 4-7 (617618.0004). The mutations, which were found by exome sequencing, were each inherited from an unaffected parent. Neither was present in the gnomAD database. Patient fibroblasts showed slightly shorter cilia length compared to controls (2.6 versus 3.0 micrometers) and a slightly lower ciliation rate compared to controls (85% versus 91%). Further detailed studies of patient fibroblasts and ciliated cells from mutant zebrafish showed reduced acetylation and polyglutamylation of axonemal microtubules compared to controls, indicating impaired posttranslational modification of tubulin, as well as abnormal ciliary stability.
