Abstract
We report the first case of mandibuloacral dysplasia with type B lipodystrophy (MADB) in Chile, South America. MADB is a very rare illness, characterized by short stature, mandibular hypoplasia, acro-osteolysis in hands, feet and clavicles, lipodystrophy, changes in skin pigments and skin calcinosis at knees and hands. Diagnosis was confirmed by molecular study that showed two compound heterozygous variants in ZMPSTE24 gene, c.1085dup p.(Leu362Phefs*19) and c.794A>G p.(Asn265Ser). This article could help in establishing the correlation between genotype and phenotype of this disorder, comparing with other cases previously described.
