Velocardiofacial syndrome

Individuals with 22q11.2 deletion syndrome (22q11.2DS) can present with a wide range of features that are highly variable, even within families. The major clinical manifestations of 22q11.2DS include congenital heart disease, particularly conotruncal malformations (ventricular septal defect, tetralogy of Fallot, interrupted aortic arch, and truncus arteriosus), palatal abnormalities (velopharyngeal incompetence, submucosal cleft palate, bifid uvula, and cleft palate), immune deficiency, characteristic facial features, and learning difficulties. Hearing loss can be sensorineural and/or conductive. Laryngotracheoesophageal, gastrointestinal, ophthalmologic, central nervous system, skeletal, and genitourinary anomalies also occur. Psychiatric illness and autoimmune disorders are more common in individuals with 22q11.2DS. [from GeneReviews]

Piebaldism

Piebaldism is a rare autosomal dominant trait characterized by the congenital absence of melanocytes in affected areas of the skin and hair. A white forelock of hair, often triangular in shape, may be the only manifestation, or both the hair and the underlying forehead may be involved. The eyebrows and eyelashes may be affected. Irregularly shaped white patches may be observed on the face, trunk, and extremities, usually in a symmetrical distribution. Typically, islands of hyperpigmentation are present within and at the border of depigmented areas (summary by Thomas et al., 2004). [from OMIM]

Distal arthrogryposis type 2B1

Distal arthrogryposis is a clinically and genetically heterogeneous disorder characterized by clenched fist, overlapping fingers, camptodactyly, ulnar deviation, and positional foot deformities from birth. It is a disorder of primary limb malformation without primary neurologic or muscle disease. DA1 is not associated with other abnormalities, whereas other forms of DA have additional phenotypic features (Bamshad et al., 1996). The congenital contractures in DA2B (Sheldon-Hall syndrome, SHS) are similar to those observed in DA1, but affected individuals tend to have more prominent nasolabial folds, downslanting palpebral fissures, and a small mouth. DA2B is thought to be the most common of the distal arthrogryposis disorders (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]

Blau syndrome

Blau syndrome is characterized by the triad of granulomatous arthritis, uveitis, and dermatitis. First described in 1985, it was considered to be distinct from sarcoidosis due to the early age of onset and autosomal dominant inheritance pattern. Published reports of sporadic cases of children with 'early-onset sarcoidosis' (EOS) with granulomatous involvement of different organs, primarily affecting joints, eyes, and skin, were suspected to represent the same disorder because the patients' characteristics were nearly identical. Subsequently, identical NOD2 mutations were identified in patients with Blau syndrome as well as in patients diagnosed with EOS, confirming earlier suspicions that they represented the same disease (summary by Borzutzky et al., 2010). Unlike older children diagnosed with sarcoidosis, these patients have no apparent pulmonary involvement; however, the disease is progressive and may result in severe complications such as blindness and/or joint destruction (Shetty and Gedalia, 1998). [from OMIM]

Otoonychoperoneal syndrome

A rare multiple congenital anomalies/dysmorphic syndrome characterized by the association of dysplastic external ears, nail hypoplasia, and variable skeletal malformations, such as hypoplastic or absent fibulae, abnormalities of the scapula, clavicle, and acromioclavicular joint, and talipes equinovarus, among others. Joint contractures and mild facial dysmorphism have also been reported. [from ORDO]

Cone-rod dystrophy 1

Cone-rod dystrophy is a group of related eye disorders that causes vision loss, which becomes more severe over time. These disorders affect the retina, which is the layer of light-sensitive tissue at the back of the eye. In people with cone-rod dystrophy, vision loss occurs as the light-sensing cells of the retina gradually deteriorate.

The first signs and symptoms of cone-rod dystrophy, which often occur in childhood, are usually decreased sharpness of vision (visual acuity) and increased sensitivity to light (photophobia). These features are typically followed by impaired color vision (dyschromatopsia), blind spots (scotomas) in the center of the visual field, and partial side (peripheral) vision loss. Over time, affected individuals develop night blindness and a worsening of their peripheral vision, which can limit independent mobility. Decreasing visual acuity makes reading increasingly difficult and most affected individuals are legally blind by mid-adulthood. As the condition progresses, individuals may develop involuntary eye movements (nystagmus).

There are more than 30 types of cone-rod dystrophy, which are distinguished by their genetic cause and their pattern of inheritance: autosomal recessive, autosomal dominant, and X-linked. Additionally, cone-rod dystrophy can occur alone without any other signs and symptoms or it can occur as part of a syndrome that affects multiple parts of the body. [from MedlinePlus Genetics]

Patterson-Stevenson-Fontaine syndrome

A very rare variant of acrofacial dysostosis with characteristics of mandibulofacial dysostosis and limb anomalies. It has been described in less than ten patients. The mandibulofacial dysostosis consists of retrognathism, complete or occult posterior cleft palate and anomalies of the external ears. Limb anomalies consist of split-foot deformity with syndactyly of some toes. The condition is transmitted as an autosomal dominant trait with variable penetrance and expressivity. [from SNOMEDCT_US]

Retinitis pigmentosa-intellectual disability-deafness-hypogenitalism syndrome

A rare syndromic retinitis pigmentosa characterized by pigmentary retinopathy, diabetes mellitus with hyperinsulinism, acanthosis nigricans, secondary cataracts, neurogenic deafness, short stature mild hypogonadism in males and polycystic ovaries with oligomenorrhea in females. Inheritance is thought to be autosomal recessive. It can be distinguished from Alstrom syndrome (see this term) by the presence of intellectual disability and the absence of renal insufficiency. There have been no further descriptions in the literature since 1993. [from ORDO]
