Summary
Context: Mandibuloacral dysplasia ( MAD) is a phenotypically heterogeneous, rare autosomal recessive disorder characterized by mandibular and clavicular hypoplasia, acroosteolysis, delayed closure of cranial sutures, joint contractures, lipodystrophy, and mottled cutaneous pigmentation. MAD patients with type A lipodystrophy with loss of sc fat from the extremities and normal or slight excess in the neck and truncal regions have been previously reported to carry a homozygous Arg527His mutation in LMNA (Lamin A/C) gene. Among those with type B pattern of lipodystrophy with generalized loss of sc fat, we recently reported a patient carrying compound heterozygous mutations in an endoprotease, zinc metalloproteinase (ZMPSTE24), gene that is involved in posttranslational processing of prelamin A to mature lamin A.
