Feingold syndrome

Feingold syndrome (FGLDS) is characterized by limb malformations, microcephaly, esophageal/duodenal atresias, and learning disability. Feingold syndrome is caused by mutations in MYCN and inherited as an autosomal dominant trait. Recently, individuals sharing the skeletal abnormalities of FGLDS but lacking mutations in MYCN, were found to harbour deletions of the MIR17HG gene. These individuals share many of the characteristics of FGLDS except for gastrointestinal atresia. The condition was termed Feingold syndrome type 2 (FGLDS2).
