PATRICIA BIGNELL (Oxford Hospitals NHS Foundation Trust)

Green List (high evidence)

I had a discussion with Cambridge and Dr WJH Griffiths to see what he recommends for patients with iron overload; advice was to include SLC25A38, GLRX5, ALAS2 and ABCB7. We have found 8 patients with Iron overload that have a variant in the above genes.

Comment on list classification: As discussed with the GMS Haematology Specialist Test Group at workshop 2nd July 2019. Gene was not submitted by all GLHs so needed further review by all the GLHs. All agreed that this gene should be in this panel and there is enough evidence to rate this gene Green.
