Variants in this GENE are reported as part of current diagnostic practice

Comment on list classification: All reports are for the same variant, in patients with Arab descent, therefore decided in the Analysis and Interpretation meeting to make this red for now as the finding has not been repeated with a seperated variant or in a seperate population.
