Green List (high evidence)

Comment on list classification: There is enough evidence for this gene to be rated GREEN at the next major review - at least 7 families (4 with same founder variant) with Joubert syndrome, which is associated with global DD/ID.

Associated with Joubert syndrome in OMIM, and a confirmed gene in G2P.

PMID: 26167768 (2015) - Homozygous founder variant (c.1910A>C, p.Asp637Ala) identified in six individuals from four Hutterite families affected with Joubert syndrome. Mild-moderate developmental delay was reported in all (but one patient who died at 15 days of age). Analysis of an additional 643 Joubert families revealed 7 families with heterozygous truncating PIBF1 variants - unclear whether these were monoallelic or compound heterozygous (one comp het case, UW155-3, included in supplementary data).

PMID: 29695797 (2018) - Biallelic in-frame insertion (p.Gln394_Leu395ins12) of 36-bp in exon 9 of PIBF1 was identified in a two-year-old girl with global developmental delay, associated with Joubert syndrome. The variant segregated with the phenotype, however no further functional validation was performed.

PMID: 30858804 (2019) - Compound heterozygous variants (p.Y503C and p.Q485*) identified in a patient with Joubert syndrome (including global developmental delay). Includes functional data using the frog Xenopus as an animal model.
