Feingold syndrome (FS), also known as oculo-digito-esophageal-duodenal (ODED) syndrome, is a rare inherited malformation syndrome characterized by microcephaly, short stature and numerous digital anomalies and is comprised of two subtypes: FS type 1 (FS1) and FS type 2 (FS2). FS1 is by far the most common form while FS2 has only been reported in 3 patients and has the same clinical characteristics as FS1, apart from the absence of gastrointestinal atresia and short palpebral fissures.
No HPO annotations are available for this condition.
Age of onset: at birth.
Feingold syndrome 1 (FS1) as described by and is characterized by digital anomalies, microcephaly, facial dysmorphism, gastrointestinal atresias, and learning disability. To date, 69 families with 116 affected individuals having three or more of the core features of FS1 (brachymesophalangy, toe syndactyly, microcephaly, short palpebral fissures, and intestinal atresia) have been reported . Features are summarized in . Table 2. Features in Feingold Syndrome 1 (FS1) Feature | % of Persons w/Feature Digital anomalies
Brachymesophalangy | 100% |
|---|---|
Facial dysmorphism | Short palpebral fissures |
Atresia | Esophageal |
Other | Renal abnormalities |

Feingold syndrome 1 (FS1) should be suspected in probands with the following clinical findings .
Digital anomalies (brachymesophalangy, thumb hypoplasia, toe syndactyly)
Microcephaly (occipito-frontal circumference 10th centile)
Short palpebral fissures
Gastrointestinal atresias, especially esophageal and duodenal, diagnosed pre- or postnatally by imaging studies (usually ultrasound examination, possibly MRI)
The diagnosis of FS1 is established in a proband with suggestive clinical findings and a heterozygous pathogenic (or likely pathogenic) variant in MYCN identified by molecular genetic testing . Note: (1) Large contiguous-gene deletions encompassing MYCN and other genes have been reported in individuals with features of FS1 but more complex ph...

No approved treatments are currently available for Feingold syndrome. The disease remains an area of unmet medical need.
Evaluations Following Initial Diagnosis To establish the extent of disease and needs in an individual diagnosed with Feingold syndrome 1 (FS1), the evaluations summarized (if not performed as part of the evaluation that led to the diagnosis) are recommended. Table 4. Recommended Evaluations Following Initial Diagnosis in Individuals with Feingold Syndrome 1 (FS1)
System/Concern | Evaluation | Comment |
|---|---|---|
Hands/Feet | Assess for digital anomalies. | Hand surgeon; Occupational therapy to assess hand function/ need for therapy; Foot specialist to assess for functional needs |
Gastrointestinal tract | Assess for gastrointestinal atresia (incl esophageal, duodenal, jejunal, anal). | Gastroenterologist/ GI surgeon |
Development | Developmental assessment | Incl eval of motor, speech-language, general cognitive, vocational skills |
Renal abnormalities | Renal ultrasound eval | Assess for renal anomalies. |
Cardiac abnormalities | Assess for congenital heart defects. | Pediatric cardiologist |
Hearing loss | Audiologic eval1 | Conductive sensorineural |
Miscellaneous | Consultation w/clinical geneticist /or genetic counselor | 1. See Hereditary Hearing Loss and Deafness Overview for details about audiologic evaluations. |
