Mandibuloacral dysplasia is a condition that causes a variety of abnormalities involving bone development, skin coloring (pigmentation), and fat distribution. People with this condition may grow slowly after birth. Most affected individuals are born with an underdeveloped lower jaw bone (mandible) and small collar bone... | What are the genetic changes related to mandibuloacral dysplasia ? | The two forms of mandibuloacral dysplasia are caused by mutations in different genes. Mutations in the LMNA gene cause MADA, and mutations in the ZMPSTE24 gene cause MADB.
