John McGrath (King's College London)

Green List (high evidence)

Most cases can be explained by 6 genes, indeed nearly 80% have mutations in these genes which clearly have type 3 supportive evidence. Based on studies of >500 patients the breakdown is usually as follows: TGM1 (32%), NIPAL4 (16%), ALOX12B (12%), CYP4F22 (8%), ABCA12 (5%), ALOXE3 (5%) . which leaves 22% split among some of the others or unknown.
