Green rating by Zornitza Stark and Olivia Niblock. Sufficient cases to support causation from PMID:28625504: In 11 patients from 8 unrelated families with Joubert syndrome-30 (MIM:617622), Van De Weghe et al. (2017, PMID:28625504) identified 10 different homozygous or compound heterozygous variants in the ARMC9 gene. Variants in the first 2 families were found by WES of 53 patients from 51 families with a clinical diagnosis of Joubert syndrome. Variants in 3 additional unrelated patients were found by targeted sequencing of the ARMC9 gene, and the remaining 2 families were ascertained from a cohort of Saudi Arabian families who underwent exome sequencing.
