Arina Puzriakova Added comment: Comment on list classification: Despite phenotypic diversity among cases with C2CD3 variants, ID/DD is consistently reported in living patients. Therefore, this gene could be promoted from Amber to Green at the next GMS panel update (added 'for-review' tag). |

Arina Puzriakova changed review comment from: - PMID: 24997988 (2014) - Two unrelated cases with OFD syndrome and biallelic variants (p.Arg62* and p.Cys1029Gly; p.Ala1304Valfs*3, respectively) in C2CD3. In a 4-year-old male, additional manifestations included severe microcephaly (-5 SD), severe ID, micropenis, and brain malformations including Molar Tooth Sign. In the second patient, a terminated foetus, severe microcephaly (-4 SD) was combined with canonical OFD symptoms, but assessment of ID was not possible. No functional studies of the variants; however, some data supporting a role of C2CD3 in cilium assembly and function. - PMID: 26092869 (2015) - Two unrelated individuals with biallelic variants in C2CD3. Clinical details are limited but both had features of Joubert syndrome (as JBTS screening study), as well as oral features including oral frenulae and/or cleft palate. No report on ID status, but could possibly be present in view of the JBTS diagnosis. One patient also harboured biallelic variants in TTC21B. - PMID: 26477546 (2015) - Compound het variants identified in two affected sibs with a classic form of JBTS and severe GDD but without any extraneural manifestations, as described in previous cases. - PMID: 27094867 (2016) - Two sibling fetuses with skeletal dysplasia, brain malformations but no microcephaly, in association with compound het variants in C2CD3. Due to termination of pregnancies, ID status could not be established. Analysis of patient-derived fibroblasts showed impaired cilium assembly. - PMID: 30097616 (2018) - Four individuals from three unrelated families with different biallelic variants in C2CD3. Each family exhibited distinct clinical phenotypes and severity of disease: Family 1: two sibs with a diagnosis of OFD including polydactyly, cleft palate and/or incomplete cleft lip, microcephaly, brain malformations and bilateral colobomas. GDD was noted in both sibs. Family 2: fetus with occipital encephalocele and a ventricular septal defect. Similar abnormalities were identified in another sib (also a terminated fetus), but DNA analysis was not performed on the latter. Family 3: one male with various fetal anomalies, and subsequent diagnosis of JBTS following identification of consistent findings on brain MRI. Other features included DD and bilateral retina colobomas.; to: - PMID: 24997988 (2014) - Two unrelated cases with OFD syndrome and biallelic variants (p.Arg62* and p.Cys1029Gly; p.Ala1304Valfs*3, respectively) in C2CD3.

| Intellectual disability - microarray and sequencing v2.486 | C2CD3 | Louise Daugherty Added comment: Comment on list classification: Changed rating of gene from Red to Amber. This gene was rated as Amber in v2.467 and incorrectly automatically demoted to Red in v2.468. This was due to a defect in the automatic PanelApp uploading tool where a reference gene list was added as a new Source (Victorian Clinical Genetics Services), and under certain conditions associated to previous sources listed, resulted in the rating of the gene being automatically changed when it should not have been. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
