Description
This panel is used for clinical indication 'R186 Hereditary haemorrhagic telangiectasia' in the NHS Genomic Medicine Service.

Further information on the testing criteria and any overlapping clinical indications can be found within (https://www.england.nhs.uk/publication/national-genomic-test-directories/) under 'R186 Hereditary haemorrhagic telangiectasia'.

The content of this panel is overseen by NHS Genomic Medicine Service governance. In addition to the evidence for a gene:disease association, this requires consideration of technical aspects of the assay(s) available.

CNVs, STRs and genes encoded by the mitochondrial genome may not be routinely included in the analysis where the panel is NOT delivered by WGS. Please contact your Genomic Laboratory Hub for information regarding specific queries.

Some of the genes in this panel cause conditions that typically present in adulthood. Please consider this when applying the panel.

This panel was originally developed for the 100,000 Genomes Project and is still being used for participants in the project. For the rare disease eligibility criteria refer to: https://www.genomicsengland.co.uk/rarediseasecriteria100K

The content of this panel (version 2.0: https://panelapp.genomicsengland.co.uk/api/v1/panels/123/?version=2.0) was signed off under NHS Genomic Medicine Service governance on (23/09/2019).
This panel will continue to be curated. New changes will be reflected in an increase to the minor version of the panel and details of these can be viewed in the 'Panel Activity' page. Periodically, these changes will be reviewed by a NHS Genomic Medicine Service evaluation process for the GMS panels.
