Flexion contracture, and Umbilical hernia

Hyperekplexia-4 is an autosomal recessive severe neurologic disorder apparent at birth. Affected infants have extreme hypertonia and appear stiff and rigid. They have little if any development, poor or absent visual contact, and no spontaneous movement, consistent with an encephalopathy. Some patients have early-onset refractory seizures, and many have inguinal or umbilical hernia. Most patients die in the first months of life due to respiratory failure or other complications (summary by Piard et al., 2018).For a general description and a discussion of genetic heterogeneity of hyperekplexia, see HKPX1 (OMIM ).

Proximal spinal muscular atrophy type 1 (SMA1) is a severe infantile form of proximal spinal muscular atrophy (see this term) characterized by severe and progressive muscle weakness and hypotonia resulting from the degeneration and loss of the lower motor neurons in the spinal cord and the brain stem nuclei.

Familial visceral myopathy is a rare hereditary myopathic degeneration of both gastrointestinal and urinary tracts that causes chronic intestinal pseudo-obstruction. It usually presents after the first decade of life with megaduodenum, megacystis and symptoms such as abdominal distension and/or pain, vomiting, constipation, diarrhea, dysphagia, and/or urinary tract infections.n.

CLIFAHDD is a congenital disorder characterized by congenital contractures of the limbs and face, resulting in characteristic facial features, hypotonia, and variable degrees of developmental delay. All reported cases have occurred de novo (summary by Chong et al., 2015).

Robinow syndrome is a skeletal dysplasia characterized by distinctive facial features, including midface hypoplasia, hypertelorism, a short nose, and a broad mouth, known collectively as 'fetal facies.' Additional features include mesomelic dwarfism, macrocephaly, gingival hypertrophy, dental malocclusion, genital hypoplasia, and brachydactyly (summary by Bunn et al., 2015). Additionally, increased skull bone density and appendicular osteosclerosis are present in patients with DRS2 (White et al., 2015; Bunn et al., 2015).For a discussion of genetic heterogeneity of Robinow syndrome, see RRS (OMIM ).

Brittle cornea syndrome is a form of Ehlers-Danlos syndrome characterized by a severe ocular manifestations due to extreme corneal thinning and fragility with rupture in the absence of significant trauma, and progression to blindness. Extraocular manifestations comprise deafness, developmental hip dysplasia, and joint hypermobility.

Ehlers-Danlos syndromes (EDS) form a heterogeneous group of hereditary connective tissue diseases characterized by joint hyperlaxity, cutaneous hyperelasticity and tissue fragility.

Ehlers-Danlos syndrome, kyphoscoliotic and deafness type is a form of Ehlers-Danlos syndrome, characterized by severe generalized hypotonia at birth with severe early-onset kyphoscolosis along with joint hypermobility (without contractures) leading to recurrent dislocations, and sensorineural hearing impairment.
