We report a novel phenotype of mandibular hypoplasia, deafness, and progeroid features with lipodystrophy (MDPL) syndrome with mutation in a Chinese girl.
Diabetic retinopathy was detected as the primary manifestation in a Chinese girl with MDPL syndrome carrying a known mutation (c.1812_1814delCTC, p.Ser605del). Typical characteristics of the syndrome including mandibular hypoplasia, deafness, progeroid features, and diabetes were detected after comprehensive examinations. The patient suffered from blurred vision and eye pain due to the neovascularization of the retina (vitreous hemorrhage and retinal detachment) and iris (neovascular glaucoma). The literature review revealed that the prevalence of hepatomegaly and abnormal triglyceride levels were significantly higher in female than in male with MDPL syndrome carrying mutations.
These results expand our knowledge regarding the clinical phenotypes of MDPL syndrome with mutations. Diabetic retinopathy is a non-negligible complication of MDPL syndrome. The phenotype varies among female and male patients with the syndrome. Hepatomegaly and abnormal triglyceride levels are more common in female patients with MDPL syndrome.
