Marfan syndrome

Marfan syndrome is a systemic disorder of connective tissue with a high degree of clinical variability. Cardinal manifestations involve the ocular, skeletal, and cardiovascular systems. FBN1 pathogenic variants associate with a broad phenotypic continuum, ranging from isolated features of Marfan syndrome to neonatal presentation of severe and rapidly progressive disease in multiple organ systems. Myopia is the most common ocular feature; displacement of the lens from the center of the pupil, seen in approximately 60% of affected individuals, is a hallmark feature. People with Marfan syndrome are at increased risk for retinal detachment, glaucoma, and early cataract formation. The skeletal system involvement is characterized by bone overgrowth and joint laxity. The extremities are disproportionately long for the size of the trunk (dolichostenomelia). Overgrowth of the ribs can push the sternum in (pectus excavatum) or out (pectus carinatum). Scoliosis is common and can be mild or severe and progressive. The major sources of morbidity and early mortality in the Marfan syndrome relate to the cardiovascular system. Cardiovascular manifestations include dilatation of the aorta at the level of the sinuses of Valsalva, a predisposition for aortic tear and rupture, mitral valve prolapse with or without regurgitation, tricuspid valve prolapse, and enlargement of the proximal pulmonary artery. With proper management, the life expectancy of someone with Marfan syndrome approximates that of the general population. [from GeneReviews]

Ectopia lentis

Dislocation or malposition of the crystalline lens of the eye. A partial displacement (or dislocation) of the lens is described as a subluxation of the lens, while a complete displacement is termed luxation of the lens. A complete displacement occurs if the lens is completely outside the patellar fossa of the lens, either in the anterior chamber, in the vitreous, or directly on the retina. If the lens is partially displaced but still contained within the lens space, then it is termed subluxation. [from HPO]

Short stature, onychodysplasia, facial dysmorphism, and hypotrichosis

SOFT syndrome is characterized by severely short long bones, peculiar facies associated with paucity of hair, and nail anomalies. Growth retardation is evident on prenatal ultrasound as early as the second trimester of pregnancy, and affected individuals reach a final stature consistent with a height age of 6 years to 8 years. Relative macrocephaly is present during early childhood but head circumference is markedly low by adulthood. Psychomotor development is normal. Facial dysmorphism includes a long, triangular face with prominent nose and small ears, and affected individuals have an unusual high-pitched voice. Clinodactyly, brachydactyly, and hypoplastic distal phalanges and fingernails are present in association with postpubertal sparse and short hair. Typical skeletal findings include short and thick long bones with mild irregular metaphyseal changes, short femoral necks, and hypoplastic pelvis and sacrum. All long bones of the hand are short, with major delay of carpal ossification and cone-shaped epiphyses. Vertebral body ossification is also delayed (summary by Sarig et al., 2012). [from OMIM]

Ehlers-Danlos syndrome, type vii, autosomal recessive

Dermatosparaxis (meaning 'tearing of skin') is an autosomal recessive disorder of connective tissue resulting from deficiency of procollagen peptidase, an enzyme that aids in the processing of type I procollagen. The disorder and the responsible biochemical defect was first observed in cattle (Lapiere et al., 1971). Lapiere and Nusgens (1993) reviewed the discovery of dermatosparaxis in cattle, the elucidation of the disorder, its occurrence in other animals, and the delayed recognition of the disorder in the human. Beighton et al. (1998) reported on a revised nosology of the Ehlers-Danlos syndromes, designated the Villefranche classification. Major and minor diagnostic criteria were defined for each type and complemented whenever possible with laboratory findings. Six main descriptive types were substituted for earlier types numbered with Roman numerals: classic type (EDS I and II), hypermobility type (EDS III), vascular type (EDS IV), kyphoscoliosis type (EDS VI), arthrochalasia type (EDS VIIA and VIIB), and dermatosparaxis type (EDS VIIC). Six other forms were listed, including a category of 'unspecified forms.' [from OMIM]
