1.17.4.4 | R98W | two patients suffering from combined deficiency of vitamin K-dependent clotting factors type 2 possess a R98W substitution at the presumed cytoplasmic end of TM alpha-helix 2 of vitamin-K-epoxide reductase. Because the residue is far-removed from the proposed active site its mutation is, therefore assumed to disrupt VKORC1 structure or VKOR complex assembly rather than catalysis | Homo sapiens |
