Intellectual disability v3.1513 CEP120 Arina Puzriakova Tag for-review was removed from gene: CEP120.
Intellectual disability v3.1510 CEP120 Sarah Leigh commented on gene: CEP120
Intellectual disability v3.1509 CEP120 Arina Puzriakova Source Expert Review Green was added to CEP120.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Intellectual disability v3.532 CEP120 Arina Puzriakova Tag for-review tag was added to gene: CEP120.
Intellectual disability v3.532 CEP120 Arina Puzriakova Classified gene: CEP120 as Amber List (moderate evidence)
Intellectual disability v3.532 CEP120 Arina Puzriakova Added comment: Comment on list classification: New gene added by Konstantinos Varvagiannis. Based on the evidence provided, this gene should be promoted to Green at the next GMS panel update (added 'for-review' tag)

4 unrelated individuals with distinct variants in the CEP120 gene and Joubert syndrome, including a neurological phenotype in all consisting of hypotonia, developmental delay and cognitive impairment (PMID:27208211).
Intellectual disability v3.532 CEP120 Arina Puzriakova Gene: cep120 has been classified as Amber List (Moderate Evidence).
Intellectual disability v3.500 CEP120 Ivone Leong Phenotypes for gene: CEP120 were changed from Joubert syndrome 31 (MIM 617761); Short-rib thoracic dysplasia 13 with or without polydactyly (MIM 616300) to Joubert syndrome 31 (617761); Short-rib thoracic dysplasia 13 with or without polydactyly (616300)
Intellectual disability v3.170 CEP120 Konstantinos Varvagiannis gene: CEP120 was added
gene: CEP120 was added to Intellectual disability. Sources: Literature
Mode of inheritance for gene: CEP120 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: CEP120 were set to 27208211
Phenotypes for gene: CEP120 were set to Joubert syndrome 31 (MIM 617761); Short-rib thoracic dysplasia 13 with or without polydactyly (MIM 616300)
Penetrance for gene: CEP120 were set to Complete
Review for gene: CEP120 was set to GREEN
Added comment: Pathogenic CEP120 variants have been reported in recessive ciliopathies, namely Short-rib thoracic dysplasia 13 with or without polydactyly (MIM 616300) and Joubert syndrome 31 (MIM 617761).

The former is associated with a severe/lethal outcome (4 unrelated infants described by Shaheen et al 2015 - PMID: 25361962, 2 fetuses reported by Roosing et al 2016 - PMID: 27208211).

Roosing et al however, also provided details on 4 unrelated subjects with Joubert syndrome diagnosis. All presented with a neurologic phenotype of hypotonia, DD, cognitive impairment and exhibited a molar tooth sign.

As a result, this gene can be considered for inclusion in the ID panel with green rating (>3 individuals/variants, consistent ciliopathy phenotype).
