Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:
141025
Concept ID:
C0441748
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 individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).
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.

Definition

Freeman-Sheldon syndrome (FSS), or DA2A, is phenotypically similar to DA1. In addition to contractures of the hands and feet, FSS is characterized by oropharyngeal abnormalities, scoliosis, and a distinctive face that includes a very small oral orifice (often only a few millimeters in diameter at birth), puckered lips, and an H-shaped dimple of the chin; hence, FSS has been called 'whistling face syndrome.' The limb phenotypes of DA1 and FSS may be so similar that they can only be distinguished by the differences in facial morphology (summary by Bamshad et al., 2009). For a general phenotypic description and a discussion of genetic heterogeneity of distal arthrogryposis, see DA1 (108120). [from OMIM]

Additional description

From MedlinePlus Genetics
Freeman-Sheldon syndrome (also known as Freeman-Burian syndrome) is a condition that primarily affects muscles in the face and skull (craniofacial muscles) and can often affect joints in the hands and feet. The condition is characterized by abnormalities known as contractures, which result from permanent tightening of muscles, skin, tendons, and surrounding tissues, and restrict movement of the affected body part. In Freeman-Sheldon syndrome, contractures in the face lead to a distinctive facial appearance including a small mouth (microstomia) with pursed lips, giving the appearance of whistling. For this reason, Freeman-Sheldon syndrome is sometimes called "whistling face syndrome." Other facial features common in this condition include a chin dimple shaped like an "H" or "V" and unusually deep folds in the skin between the nose and the corners of the mouth (nasolabial folds).

People with Freeman-Sheldon syndrome may also have a variety of other facial features, such as a prominent forehead and brow ridges, a sunken appearance of the middle of the face (midface hypoplasia), a short nose, a long area between the nose and mouth (philtrum), and full cheeks. Affected individuals may have a number of abnormalities that affect the eyes. These features can include widely spaced eyes (hypertelorism), deep-set eyes, outside corners of the eyes that point downward (down-slanting palpebral fissures), a narrowing of the eye opening (blepharophimosis), droopy eyelids (ptosis), and eyes that do not look in the same direction (strabismus).

Other features that can occur in Freeman-Sheldon syndrome include an unusually small tongue (microglossia) and jaw (micrognathia) and a high arch in the roof of the mouth (high-arched palate). People with Freeman-Sheldon syndrome may have difficulty swallowing (dysphagia), a failure to gain weight and grow at the expected rate (failure to thrive), and breathing complications that may be life-threatening. Speech problems or hearing impairment can also occur in people with this disorder.

In people with Freeman-Sheldon syndrome, contractures in the hands and feet can lead to permanently bent fingers and toes (camptodactyly), a hand deformity in which all of the fingers are angled outward toward the fifth finger (ulnar deviation, also called "windmill vane hand"), and inward- and downward-turning feet (clubfoot). Less commonly, contractures affect the hips, knees, shoulders, or elbows.

People with Freeman-Sheldon syndrome may also have abnormalities of the spine, ribs, or chest. Many affected individuals have abnormal side-to-side or front-to-back curvature of the spine (scoliosis or kyphosis) or an abnormally curved lower back (lordosis). In many affected individuals, the muscles between the ribs do not function properly, which can impair breathing or coughing. The ribs or breastbone (sternum) may be abnormally shaped in people with this condition.

Intelligence is unaffected in most people with Freeman-Sheldon syndrome, but development of normal milestones may be delayed due to physical abnormalities.  https://medlineplus.gov/genetics/condition/freeman-sheldon-syndrome

Clinical features

From HPO
Arthralgia
MedGen UID:
13917
Concept ID:
C0003862
Sign or Symptom
Joint pain.
Cryptorchidism
MedGen UID:
8192
Concept ID:
C0010417
Congenital Abnormality
Cryptorchidism, or failure of testicular descent, is a common human congenital abnormality with a multifactorial etiology that likely reflects the involvement of endocrine, environmental, and hereditary factors. Cryptorchidism can result in infertility and increases risk for testicular tumors. Testicular descent from abdomen to scrotum occurs in 2 distinct phases: the transabdominal phase and the inguinoscrotal phase (summary by Gorlov et al., 2002).
Chordee

Abnormal position of urethral meatus on the ventral penile shaft (underside) characterized by displacement of the urethral meatus from the tip of the glans penis to the ventral surface of the penis, scrotum, or perineum.
Clubfoot
MedGen UID:
3130
Concept ID:
C0009081
Congenital Abnormality
Clubfoot is a congenital limb deformity defined as fixation of the foot in cavus, adductus, varus, and equinus (i.e., inclined inwards, axially rotated outwards, and pointing downwards) with concomitant soft tissue abnormalities (Cardy et al., 2007). Clubfoot may occur in isolation or as part of a syndrome (e.g., diastrophic dysplasia, 222600). Clubfoot has been reported with deficiency of long bones and mirror-image polydactyly (Gurnett et al., 2008; Klopocki et al., 2012).
Congenital vertical talus
MedGen UID:
66821
Concept ID:
C0240912
Congenital Abnormality
Congenital vertical talus (CVT), also known as 'rocker-bottom foot' deformity, is a dislocation of the talonavicular joint characterized by vertical orientation of the talus with a rigid dorsal dislocation of the navicular, equinus deformity of the calcaneus, abduction deformity of the forefoot, and contracture of the soft tissues of the hind- and mid-foot. This condition is usually associated with multiple other congenital deformities and only rarely is an isolated deformity with familial occurrence (summary by Levinsohn et al., 2004). The condition is transmitted in an autosomal dominant pattern of inheritance, and sometimes shows incomplete penetrance and variable expressivity. There may be a broad spectrum of deformities, including flatfoot, talipes equinovarus (TEV or clubfoot), cavus foot, metatarsus adductus, and even hypoplasia of the tibia (summary by Dobbs et al., 2006).
