Louise Daugherty (Genomics England Curator)

Comment on list classification: Changed rating of gene from Red to Green. This gene was rated as Green 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.

Comment when marking as ready: ID is a relatively common feature, therefore include. Broader phenotypic spectrum noted.

Sarah Leigh (Genomics England Curator)

Green List (high evidence)

Associated with phenotype in OMIM and as a confirmed G2P for Timothy syndrome 601005. At least 3 variants reported in numerous cases. Sudden death frequently occurs in Timothy syndrome 601005 due to cardiac arrest. Mental retardation reported in 25% of cases (PMID 15454078), PMID 28371864 states that Surviving patients seem to have mild developmental delay and learning difficulties.
