Mulibrey nanism is a rare genetic disorder characterized by profound growth delays and distinctive abnormalities of the muscles, liver, brain, and eyes. The acronym MULIBREY stands for (MU)scle, (LI)ver, (BR)ain, and (EY)e; nanism is another word for dwarfism. Signs and symptoms of the disorder may include constrictive pericarditis; low birth weight; short stature; severe progressive growth delays; hypotonia; hepatomegaly; and yellow discoloration of the eyes in infancy. It is caused by mutations in the TRIM37 gene and is inherited in an autosomal recessive manner. Treatment may include surgery for constrictive pericarditis, medications for progressive heart failure and hormone replacement therapy.
