Low match MUSCULAR DYSTROPHY-DYSTROGLYCANOPATHY (CONGENITAL WITH BRAIN AND EYE ANOMALIES), TYPE A, 11; MDDGA11

Congenital muscular dystrophy-dystroglycanopathy with brain and eye anomalies (type A) is an autosomal recessive disorder with congenital muscular dystrophy resulting in muscle weakness early in life and brain and eye anomalies. It is usually associated with delayed psychomotor development and shortened life expectancy. The phenotype includes the alternative clinical designations Walker-Warburg syndrome (WWS) and muscle-eye-brain disease (MEB). The disorder represents the most severe end of a phenotypic spectrum of similar disorders resulting from defective glycosylation of alpha-dystroglycan (DAG1 ), collectively known as 'dystroglycanopathies' (summary by Stevens et al., 2013).For a general phenotypic description and a discussion of genetic heterogeneity of muscular dystrophy-dystroglycanopathy type A, see MDDGA1 (OMIM ).

Cobblestone lissencephaly without muscular or ocular involvement is a form of cobblestone lissencephaly characterized by a constellation of brain malformations which can either exist alone or in conjunction with minimal muscular and ocular abnormalities. The clinical features of the disease include severe developmental delay, increased head circumference, hydrocephalus and seizures.

Autosomal recessive SPG9B is a neurologic disorder characterized by early-onset complex spastic paraplegia. Affected individuals had delayed psychomotor development, intellectual disability, and severe motor impairment. More variable features include dysmorphic facial features, tremor, and urinary incontinence (summary by Coutelier et al., 2015).For a discussion of genetic heterogeneity of autosomal recessive SPG, see SPG5A (OMIM ).

Autosomal dominant familial hematuria-retinal arteriolar tortuosity-contractures syndrome is characterised by the association of hematuria (without proteinuria) with extrarenal manifestations: retinal arterial tortuosities responsible for retinal haemorrhages, cardiac arrhythmia, Raynaud phenomena and congenital muscular contractures.

Low match MUSCULAR DYSTROPHY-DYSTROGLYCANOPATHY (CONGENITAL WITH BRAIN AND EYE ANOMALIES), TYPE A, 2; MDDGA2

Congenital muscular dystrophy-dystroglycanopathy with brain and eye anomalies (type A), which includes both the more severe Walker-Warburg syndrome (WWS) and the slightly less severe muscle-eye-brain disease (MEB), is an autosomal recessive disorder with characteristic brain and eye malformations, profound mental retardation, congenital muscular dystrophy, and death usually in the first years of life. It represents the most severe end of a phenotypic spectrum of similar disorders resulting from defective glycosylation of DAG1 (OMIM ), collectively known as 'dystroglycanopathies' (van Reeuwijk et al., 2005).For a general phenotypic description and a discussion of genetic heterogeneity of muscular dystrophy-dystroglycanopathy type A, see MDDGA1 (OMIM ).

Low match FAMILIAL PORENCEPHALY

Porencephaly is a term used for any cavitation or cerebrospinal fluid-filled cyst in the brain. One form, called encephaloclastic, or type 1, porencephaly, is usually unilateral and results from focal destructive lesions such as fetal vascular occlusion or birth trauma. Another form, called schizencephalic, or type 2, porencephaly, is usually symmetric and represents a primary defect or arrest in the development of the cerebral ventricles. Encephaloclastic porencephaly is more common (Airaksinen, 1984; Sensi et al., 1990). Genetic Heterogeneity of PorencephalySee also POREN2 (OMIM ), caused by mutation in the COL4A2 gene (OMIM ).

Low match MYOTONIC DYSTROPHY 2; DM2

Myotonic dystrophy (DM) is a multisystem disorder and the most common form of muscular dystrophy in adults. Individuals with DM2 have muscle pain and stiffness, progressive muscle weakness, myotonia, male hypogonadism, cardiac arrhythmias, diabetes, and early cataracts. Other features may include cognitive dysfunction, hypersomnia, tremor, and hearing loss (summary by Heatwole et al., 2011).See also myotonic dystrophy-1 (DM1 ), caused by an expanded CTG repeat in the dystrophia myotonica protein kinase gene (DMPK ) on 19q13.Although originally reported as 2 disorders, myotonic dystrophy-2 and proximal myotonic myopathy are now referred to collectively as DM2 (Udd et al., 2003).
