Sophie Hambleton (Newcastle University)

Green List (high evidence)

Agree with Tracy, very high confidence that mutations in this gene cause severe pseudo-TORCH picture

Tracy Briggs (Manchester Genomic Medicine Centre)

Green List (high evidence)

I think USP18 should be green: five PTS patients from two unrelated families

The amber genes are covered on our targeted exome, we feel that these should be covered in the testing

I don't know

Gene was flagged as requiring further clinical input from the Immunology Test Group, but no additional information was submitted to support the Green rating. In view of a lack of clear evidence the current recommendation is Amber.

Pseudo TORCH syndrome: Aicardi-Goutiere like - severe intracranial haemorrhage, thrombocytopaenia, seizures, liver failure caused by interferon activation - probable green association, is it a relevant phenotype?
2 families (one homozygous, one compound het where one variant was the same as the first family with possible common ancestor) - borderline, with lack of USP18 expression - abnormal activation of the immune system (interferon) - is this a likely presentation in immunology clinic?

Comment on list classification: Changed rating from Red to Amber to reflect the agreed rating agreed by the GMS Immunology Specialist Test Group, but flagged for further follow up with the Immunology Test Group due to the subsequent conflicting review. Evidence /opinion needs consensus before upgrading to Green

Gene rating submitted by Tracy Briggs, David Gokhale and Abigal Rousseau on behalf of North West GLH for the GMS Immunology specialist test group. Although discussed with the GMS Immunology Specialist Test Group during webex call 28th March 2019 to rate Amber in the confirmed follow up email on 20th June North West GLH reasserted that USP18 should be Green

Gene rating submitted by Kimberly Gilmour and Austen Worth on behalf of London North GLH for the GMS Immunology specialist test group. As discussed with the GMS Immunology Specialist Test Group during webex call 28th March 2019 and confirmed in follow up email 6th September the Specialist Test Group all agreed there is only enough evidence to rate this gene Amber
