Intellectual disability - microarray and sequencing v3.1510 CEP120 Sarah Leigh commented on gene: CEP120
Intellectual disability - microarray and sequencing 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 - microarray and sequencing v3.532 CEP120 Arina Puzriakova Tag for-review tag was added to gene: CEP120.
Intellectual disability - microarray and sequencing v3.532 CEP120 Arina Puzriakova Classified gene: CEP120 as Amber List (moderate evidence)
Intellectual disability - microarray and sequencing 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 - microarray and sequencing v3.532 CEP120 Arina Puzriakova Gene: cep120 has been classified as Amber List (Moderate Evidence).
Intellectual disability - microarray and sequencing 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 - microarray and sequencing 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).
