Feingold syndrome

Feingold syndrome
Other names: Oculodigitoesophagoduodenal syndrome
Feingold Syndrome is inherited in an autosomal dominant fashion.

Feingold syndrome (also called oculodigitoesophagoduodenal syndrome) is a rare autosomal dominant hereditary disorder. It is named after Murray Feingold, an American physician who first described the syndrome in 1975. Until 2003, at least 79 patients have been reported worldwide.[1]

Signs and symptoms

Syndactyly of 2nd and 3rd or 4th and 5th toe

Feingold syndrome is marked by various combinations of microcephaly, limb malformations, esophageal and duodenal atresias. Cognition is affected, and ranges from below-average IQ to mild intellectual disability.[2]

Genetics

Feingold syndrome is caused by mutations in the neuroblastoma-derived V-myc avian myelocytomatosis viral-related oncogene (MYCN) which is located on the short arm of chromosome 2 (2p24.1). This syndrome has also been linked to microdeletions in the MIR17HG locus which encodes a micro RNA cluster known as miR-17/92.[3]

Diagnosis

The diagnosis is based on the following clinical findings:

Treatment

There is no known treatment for the disorder, but surgery for malformations, special education, and treatment of hearing loss are important.[4]
