Feingold Syndrome Research Articles

Syndrome de Feingold

Feingold syndrome is a combination of hand and foot anomalies, microcephaly, tracheo-esophageal fistula, esophageal/duodenal atresia, short palpebral fissures and developmental delay. The most frequent physical findings are clinodactyly of the second and fifth fingers with absent or hypoplastic middle phalanges, and syndactyly of the toes. Inheritance is autosomal dominant (MIM number 164280) with full penetrance concerning hand anomalies, variable expressivity and great intrafamilial variability. We report the case of an African boy with duodenal atresia, microcephaly, brachymesophalangy of the second and fifth fingers, unilateral thumb hypoplasia, bilateral syndactyly of toes 2-3 and amesophalangy of the toes. Karyotype was normal. No other member of the family was affected. A fresh mutation is possible. Brachymesophalangy affecting mainly the second and fifth fingers and amesophalangy of the lateral toes are cardinal clinical findings in Feingold syndrome. These clinical findings define the syndrome of brachydactyly A4-Temtamy type (MIM 112800), suggesting that brachydactyly A4 would be a partially expressed Feingold syndrome. The incidence of esophageal/duodenal atresia is 29%, including all the known cases. All karyotypes of reported patients were normal.

Imperforate anus in Feingold syndrome

A father and daughter had the characteristic findings of Feingold syndrome including microcephaly, short palpebral fissures, brachydactyly with clinodactyly of fifth fingers, and bilateral syndactyly of second to third and fourth to fifth toes. The infant presented with long-gap esophageal atresia without fistula (type A). Her father, who had short stature and learning disabilities, had congenital imperforate anus with a recto-vesical fistula. This is the first report of distal intestinal atresia in Feingold syndrome.

Familial Syndromic Esophageal Atresia Maps to 2p23-p24

Esophageal atresia (EA) is a common life-threatening congenital anomaly that occurs in 1/3,000 newborns. Little is known of the genetic factors that underlie EA. Oculodigitoesophageoduodenal (ODED) syndrome (also known as "Feingold syndrome") is a rare autosomal dominant disorder with digital abnormalities, microcephaly, short palpebral fissures, mild learning disability, and esophageal/duodenal atresia. We studied four pedigrees, including a three-generation Dutch family with 11 affected members. Linkage analysis was initially aimed at chromosomal regions harboring candidate genes for this disorder. Twelve different genomic regions covering 15 candidate genes (approximately 15% of the genome) were excluded from involvement in the ODED syndrome. A subsequent nondirective mapping approach revealed evidence for linkage between the syndrome and marker D2S390 (maximum LOD score 4.51 at recombination fraction 0). A submicroscopic deletion in a fourth family with ODED provided independent confirmation of this genetic localization and narrowed the critical region to 7.3 cM in the 2p23-p24 region. These results show that haploinsufficiency for a gene or genes in 2p23-p24 is associated with syndromic EA.

Feingold syndrome: Report of a new family and review

Feingold syndrome (or oculodigitoesophagoduodenal syndrome; Microcephaly, Mesobrachyphalangy, Tracheo-esophageal fistula syndrome) is a dominantly inherited combination of hand and foot abnormalities, microcephaly, esophageal/duodenal atresia, short palpebral fissures and learning disabilities, first reported in 1975 (MIM 164280). We report on the seventh family with Feingold syndrome. The propositus is a male infant with esophageal and duodenal atresia, brachymesophalangy of the fifth fingers, bilateral syndactyly of toes 4-5 (and 2-3), relative microcephaly, and facial anomalies. His mother also has microcephaly, similar facial appearance, short fifth fingers with single flexion crease, syndactyly of toes 4-5, and learning disabilities. The maternal sister, brother, and grandmother of the propositus have the same phenotype. The 7 families with Feingold syndrome are reviewed. Intestinal (esophageal/duodenal) atresia/obstruction occurs in approximately 1/3 of the patients with Feingold syndrome.
