Medium match CONGENITAL LETHAL MYOPATHY, COMPTON-NORTH TYPE

Congenital lethal myopathy, Compton-North type is a rare, genetic, lethal, non-dystrophic congenital myopathy disorder characterized, antenatally, by fetal akinesia, intrauterine growth restriction and polyhydramnios, and, following birth, by severe neonatal hypotonia, severe generalized skeletal, bulbar and respiratory muscle weakness, multiple flexion contractures, and normal creatine kinase serum levels. Ultrastructurally, loss of integrin alpha7, beta2-syntrophin and alpha-dystrobrevin from the muscle sarcolemma and disruption of sarcomeres with disorganization of the Z band are observed.

Medium match ARTHROGRYPOSIS, DISTAL, WITH IMPAIRED PROPRIOCEPTION AND TOUCH; DAIPT

Distal arthrogryposis with impaired proprioception and touch is an autosomal recessive neurologic disorder characterized by loss of certain mechanosensation modalities resulting in ataxia, difficulty walking, dysmetria, muscle weakness and atrophy, and progressive skeletal contractures. Patients have onset of symptoms in early childhood (summary by Chesler et al., 2016 and Delle Vedove et al., 2016).

The musculocontractural type of Ehlers-Danlos syndrome is characterized by progressive multisystem fragility-related manifestations, including joint dislocations and deformities; skin hyperextensibility, bruisability, and fragility, with recurrent large subcutaneous hematomas; cardiac valvular, respiratory, gastrointestinal, and ophthalmologic complications; and myopathy, featuring muscle hypoplasia, muscle weakness, and an abnormal muscle fiber pattern in histology in adulthood, resulting in gross motor developmental delay (summary by Muller et al., 2013).For a discussion of genetic heterogeneity of the musculocontractural type of Ehlers-Danlos syndrome, see EDSMC1 (OMIM ).

Nakajo-Nishimura syndrome (NNS) is a rare autoinflammatory disorder belonging to the proteasome disability syndrome (see this term) group, and characterized by pernio-like lesions appearing in infancy followed by recurrent fever, nodular skin eruption, partial lipodystrophy (mainly in upper extremities and face) and joint contractures.

Low match EHLERS-DANLOS SYNDROME DUE TO TENASCIN-X DEFICIENCY

Ehlers-Danlos syndrome due to tenascin-X deficiency is a type of Ehlers-Danlos syndrome characterized by generalized joint hypermobility, skin hyperextensibility and easy bruising without atrophic scarring. Other common features include foot and hand deformities (piezogenic papules, pes planus, broad forefeet, brachydactyly, and acrogenic skin of hands), severe fatigue and neuromuscular symptoms including muscle weakness and myalgia.

Low match OCULOCEREBROFACIAL SYNDROME, KAUFMAN TYPE

Oculocerebrofacial syndrome, Kaufman type is characterized by psychomotor retardation, microcephaly, upslanting palpebral fissures, eye abnormalities (microcornea, strabismus, myopia, optic atrophy), high-arched palate, preauricular skin tags and micrognathia with respiratory distress. It has been described in about 10 cases. Other anomalies can be present: long thin hands and feet, ambiguous genitalia, hypertelorism, etc. An autosomal recessive mode of inheritance seems most likely.

Low match MARFAN SYNDROME; MFS

A heritable disorder of fibrous connective tissue, Marfan syndrome shows striking pleiotropism and clinical variability. The cardinal features occur in 3 systems--skeletal, ocular, and cardiovascular (McKusick, 1972; Pyeritz and McKusick, 1979; Pyeritz, 1993). It shares overlapping features with congenital contractural arachnodactyly (OMIM ), which is caused by mutation in the FBN2 gene (OMIM ).Gray and Davies (1996) gave a general review. They published Kaplan-Meier survival curves for a cohort of British Marfan syndrome patients demonstrating greater survivorship in females than in males; a similar result had been reported by Murdoch et al. (1972) and by Silverman et al. (1995). Gray and Davies (1996) also proposed a grading scale for clinical comparison of the Marfan syndrome patients. The authors provided criteria for each grade and suggested uniform use of these scales may facilitate clinicomolecular correlations.
