Modes of inheritance:
Autosomal dominant inheritance
MedGen UID:
141047
Concept ID:
C0443147
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Disease characteristics

Excerpted from the GeneReview: Feingold Syndrome 1
Feingold syndrome 1 (referred to as FS1 in this GeneReview) is characterized by digital anomalies (shortening of the 2nd and 5th middle phalanx of the hand, clinodactyly of the 5th finger, syndactyly of toes 2-3 and/or 4-5, thumb hypoplasia), microcephaly, facial dysmorphism (short palpebral fissures and micrognathia), gastrointestinal atresias (primarily esophageal and/or duodenal), and mild-to-moderate learning disability. [from GeneReviews]

Additional descriptions

From OMIM
Feingold syndrome is an autosomal dominant disorder characterized by variable combinations of microcephaly, limb malformations, esophageal and duodenal atresias, and learning disability/mental retardation. Hand and foot abnormalities may include hypoplastic thumbs, clinodactyly of second and fifth fingers, syndactyly (characteristically between second and third and fourth and fifth toes), and shortened or absent middle phalanges. Cardiac and renal malformations, vertebral anomalies, and deafness have also been described in a minority of patients (summary by Teszas et al., 2006). Genetic Heterogeneity of Feingold Syndrome Feingold syndrome-2 (FGLDS2; 614326) is caused by hemizygous deletion of the MIR17HG gene (609415) on chromosome 13q31.3.  http://www.omim.org/entry/164280
From MedlinePlus Genetics
Feingold syndrome is a disorder that affects many parts of the body. There are two types of Feingold syndrome, distinguished by their genetic cause; both types have similar features that can vary among affected individuals.

Individuals with Feingold syndrome type 1 or type 2 have characteristic abnormalities of their fingers and toes. Almost all people with this condition have a specific hand abnormality called brachymesophalangy, which refers to shortening of the second and fifth fingers. Other common abnormalities include fifth fingers that curve inward (clinodactyly), underdeveloped thumbs (thumb hypoplasia), and fusion (syndactyly) of the second and third toes or the fourth and fifth toes.

People with Feingold syndrome type 1 are frequently born with a blockage in part of their digestive system called gastrointestinal atresia. In most cases, the blockage occurs in the esophagus (esophageal atresia) or in part of the small intestine (duodenal atresia). Individuals with type 2 do not have gastrointestinal atresias.

Additional common features of both types of Feingold syndrome include an unusually small head size (microcephaly), a small jaw (micrognathia), a narrow opening of the eyelids (short palpebral fissures), and mild to moderate learning disabilities. Less often, affected individuals have hearing loss, short stature, or kidney or heart abnormalities.  https://medlineplus.gov/genetics/condition/feingold-syndrome

Congenital Abnormality
Syndactyly with fusion of toes two and three.
Patent ductus arteriosus
MedGen UID:
4415
Concept ID:
C0013274
Congenital Abnormality
In utero, the ductus arteriosus (DA) serves to divert ventricular output away from the lungs and toward the placenta by connecting the main pulmonary artery to the descending aorta. A patent ductus arteriosus (PDA) in the first 3 days of life is a physiologic shunt in healthy term and preterm newborn infants, and normally is substantially closed within about 24 hours after bith and completely closed after about three weeks. Failure of physiologcal closure is referred to a persistent or patent ductus arteriosus (PDA). Depending on the degree of left-to-right shunting, PDA can have clinical consequences.
Ventricular septal defect
MedGen UID:
42366
Concept ID:
C0018818
Congenital Abnormality
A hole between the two bottom chambers (ventricles) of the heart. The defect is centered around the most superior aspect of the ventricular septum.
Tricuspid stenosis
MedGen UID:
21678
Concept ID:
C0040963
Disease or Syndrome
A narrowing of the orifice of the tricuspid valve of the heart.
Aortic arch interruption
MedGen UID:
57773
Concept ID:
C0152419
Congenital Abnormality
Non-continuity of the arch of aorta with an atretic point or absent segment.
Tricuspid atresia
MedGen UID:
67034
Concept ID:
C0243002
Congenital Abnormality
Failure to develop of the tricuspid valve and thus lack of the normal connection between the right atrium and the right ventricle.
Esophageal atresia
MedGen UID:
4545
Concept ID:
C0014850
Congenital Abnormality
A developmental defect resulting in complete obliteration of the lumen of the esophagus such that the esophagus ends in a blind pouch rather than connecting to the stomach.
Annular pancreas
MedGen UID:
56211
Concept ID:
C0149955
Congenital Abnormality
A congenital anomaly in which the pancreas completely (or sometimes incompletely) encircles the second portion of duodenum and occasionally obstructs the more proximal duodenum.
Duodenal atresia
MedGen UID:
75602
Concept ID:
C0266174
Congenital Abnormality
A developmental defect resulting in complete obliteration of the duodenal lumen, that is, an abnormal closure of the duodenum.
Jejunal atresia
MedGen UID:
75603
Concept ID:
C0266175
Congenital Abnormality
Jejunal atresia is the most common cause of bowel obstruction in the newborn. In this condition, because of agenesis of the mesentery, the distal small bowel comes straight off the caecum and twists around the marginal artery, suggesting a maypole, a Christmas tree, or an apple peel at operation. Obliteration of the superior mesenteric artery may underlie this malformation.
