Comment on list classification: Updated rating from Grey to Amber. Probable DD-G2P gene for Joubert Syndrome. 2 unrelated families from 1 paper. Biochemical assays in the paper (PMID:28965847) show that SUFU missense variants impair GLI3 binding, but further cases and/or animal model required for diagnostic rating.

As the Reviewers state, PMID:28965847 (De Mori et al., 2017) performed whole-exome sequencing in subjects with Joubert syndrome and identified 4 children from 2 unrelated families (Italian and Egyptian) carrying homozygous missense variants in SUFU; c.1217T-C, NM_016169.3, p.I406T in the Italians, and c.527A-G, NM_016169.3, p.H176R in the Egyptians. The Italian patients also carried a homozygous T716S mutation in the CDHR1 gene. Three of the children had postaxial polydactyly.

Green List (high evidence)

Four mutations in two consanguineous families, causing a complex Joubert-like phenotype with dysmorphic features and a molar tooth sign. Extensive laboratory evidence also provided on the role of this gene in cilial function. The paper (28965847) is from two of the largest groups in the Joubert syndrome/ciliopathy field, so although it is only one publication I think it just makes it into the green list, but with review recommended.

I don't know

4 individuals from two unrelated families reported in the literature with hypomorphic bi-allelic variants in this gene and a Joubert syndrome phenotype. Probably merits Amber.
