2 Figure 1 Clinical Features of KIF11 Mutation-Positive Patients with MLCRD and CDMMR (A) Facial features of individuals diagnosed with MLCRD. (B) Facial features of individuals diagnosed with CDMMR. The faces in (A) and (B) are characteristic of the syndrome and have upslanting palpebral fissures, a broad nose with a rounded tip, a long philtrum with a thin upper lip, a prominent chin, and prominent ears. (C) A composite color photograph of the left fundus in patient CDMMR05 II-1 shows focal areas of peripheral chorioretinal atrophy. (D) Bilateral, congenital lower-limb primary lymphedema in subjects with MLCRD involves the dorsa of the feet, which show pitting edema, deep interphalangeal creases, small dysplastic nails, and wide-caliber veins. (E) Comparison of lower-limb lymphoscintigraphy (imaging taken 2 hr after injection of radioactive isotope [technetium 99] into the webspaces between the toes) in patient MLCRD01 II-2 and an unaffected control. The patient's lymphoscintigraphy shows no significant main-tract filling and therefore suggests initial lymphatic-vessel dysfunction.
