Cataract, and Dandy-Walker malformation

Congenital cataract-hearing loss-severe developmental delay syndrome is a rare, genetic, lethal, neurometabolic disease characterized by congenital cataracts, sensorineural hearing loss, severe psychomotor developmental delay, severe, generalized muscular hypotonia, and central nervous system abnormalities (incl. cerebellar and cerebral hypoplasia, hypomyelination, wide subarachnoid spaces), in the presence of low serum copper and ceruloplasmin. Nystagmus and seizures have also been reported.

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' (Godfrey et al., 2007).For a general phenotypic description and a discussion of genetic heterogeneity of muscular dystrophy-dystroglycanopathy type A, see MDDGA1 (OMIM ).

It 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 Roscioli et al., 2012).For a general phenotypic description and a discussion of genetic heterogeneity of muscular dystrophy-dystroglycanopathy type A, see MDDGA1 (OMIM ).

JABELS is an autosomal recessive neurodevelopmental disorder characterized by developmental delay and intellectual disability with additional variable features. Patients have onset of symptoms in infancy, but the severity is highly variable. Some patients have social interaction and learn to walk but have an ataxic gait and abnormal movements, such as tremor or dystonia, whereas others do not achieve any motor control and are unable to speak. Additional features may include retinal anomalies, visual impairment, microcephaly, abnormal foot or hand posturing, and kyphoscoliosis; some patients have dysmorphic facial features or seizures. Brain imaging typically shows cerebellar atrophy and hypoplasia of the corpus callosum (summary by Jaberi et al., 2016 and Bertoli-Avella et al., 2018).

Meckel syndrome (MKS) is a rare, lethal, genetic, multiple congenital anomaly disorder characterized by the triad of brain malformation (mainly occipital encephalocele), large polycystic kidneys, and polydactyly, as well as associated abnormalities that may include cleft lip/palate, cardiac and genital anomalies, central nervous system (CNS) malformations, liver fibrosis, and bone dysplasia.

ALKKUCS is an autosomal recessive severe neurodevelopmental disorder characterized by arthrogryposis, brain abnormalities associated with cerebral parenchymal underdevelopment, and global developmental delay. Most affected individuals die in utero or soon after birth. Additional abnormalities may include hypotonia, dysmorphic facial features, and involvement of other organ systems, such as cardiac or renal. The few patients who survive have variable intellectual disability and may have seizures (summary by Gueneau et al., 2018).

The DOOR syndrome is an acronym for deafness, onychodystrophy, osteodystrophy, and mental retardation. Cantwell (1975) suggested this designation for the disorder, which can also include triphalangeal thumbs, seizures, and abnormal dermatoglyphics. Inheritance is autosomal recessive.See also DDOD syndrome (OMIM ), which shows autosomal dominant inheritance of congenital deafness and onychodystrophy without mental retardation.
