A rare primary bone dysplasia characterized by postnatal growth retardation, generalized lipodystrophy, skeletal (delayed closure of sutures, clavicular hypoplasia, dysplastic femoral head, acroosteolysis of distal phalanges, osteopenia/osteoporosis) and cardiac manifestations (including left ventricular hypertrophy, mitral valve calcifications/prolapse/insufficiency and mitral regurgitation), skin changes (atrophic skin, poikiloderma and hyperkeratosis), progeroid traits, and dysmorphic facial features (including prominent eyes, long pinched nose, full cheeks, microstomia and mandibular hypoplasia).
