Fetal anomalies v1.836 CDK8 Arina Puzriakova Tag Q4_21_rating was removed from gene: CDK8.
Fetal anomalies v1.836 CDK8 Arina Puzriakova commented on gene: CDK8: The rating of this gene has been updated following NHS Genomic Medicine Service approval.
Fetal anomalies v1.835 CDK8 Arina Puzriakova Source Expert Review Green was added to CDK8.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Fetal anomalies v1.752 CDK8 Arina Puzriakova Publications for gene: CDK8 were set to PMID: 31742715; 30905399
Fetal anomalies v1.751 CDK8 Arina Puzriakova Phenotypes for gene: CDK8 were changed from Syndromic developmental disorder with hypotonia and behavioural abnormalities to Intellectual developmental disorder with hypotonia and behavioral abnormalities, OMIM:618748
Fetal anomalies v1.750 CDK8 Arina Puzriakova Classified gene: CDK8 as Amber List (moderate evidence)
Fetal anomalies v1.750 CDK8 Arina Puzriakova Added comment: Comment on list classification: Following curation and clinical review it has been agreed that the associated phenotype is fetally-relevant and therefore this gene should be promoted to Green at the next GMS panel update (added 'Q4_21_rating' tag)
Fetal anomalies v1.750 CDK8 Arina Puzriakova Gene: cdk8 has been classified as Amber List (Moderate Evidence).
Fetal anomalies v1.749 CDK8 Arina Puzriakova Tag Q4_21_rating tag was added to gene: CDK8.
Fetal anomalies v1.749 CDK8 Rhiannon Mellis gene: CDK8 was added
gene: CDK8 was added to Fetal anomalies. Sources: Literature,Expert Review
Mode of inheritance for gene: CDK8 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: CDK8 were set to PMID: 31742715; 30905399
Phenotypes for gene: CDK8 were set to Syndromic developmental disorder with hypotonia and behavioural abnormalities
Review for gene: CDK8 was set to GREEN
Added comment: This gene and phenotype were reviewed during a meeting on 21st October 2021 between representatives of the North Thames and Central & South R21 testing GLHs.

Clinical review and curation was performed by Lyn Chitty, Alison Male, Rowenna Roberts, Rhiannon Mellis (North Thames GLH) and Stephanie Allen, Denise Williams and Esther Kinning (Central & South GLH).

Outcome of review: Confirmed that the phenotype is fetally relevant, support adding to the Fetal anomalies panel as a Green gene.

Already rated Green on the following other PanelApp panel(s): Intellectual disability; Severe paediatric disorders

Details of review:
Aggarwal et al 2020 report a heterozygous nonsense variant in a fetus with ventriculomegaly and Ebstein anomaly resulting in IUFD. Post-mortem found additionally congenital diaphragmatic hernia, common atrium and facial dysmorphism. This nonsense variant is at the same position as a hotspot for missense variants reported in a paediatric cohort (Calpena et al 2019, PMID: 30905399) with overlapping but milder phenotype: half of the 12 children in that cohort had cardiac defects, most had dysmorphic features - hence Aggarwal et al propose that this is a more severe (prenatal) presentation of the same multiple malformation syndrome, caused here by a nonsense rather than missense mutation.
