DHODH and postaxial acrofacial dysostosis: In the case of Miller syndrome, for which mutations have been reported in several papers, three mutations [p.Arg135Cys (NHLBI EA, 0.0607%), p.Gly152Arg (0.120%), and p.Arg346Try (0.161%)] should be given first priority for DHODH mutation screening in Europeans but not Africans.
