Cerebro-ocular dysplasia-muscular dystrophy (COD-MD) syndrome is a rare disorder encompassing a triad of brain, eye, and muscle abnormalities. The principal central nervous system features are cerebral and cerebellar agyria-micropolygyria, cortical disorganization, glial-mesodermal proliferation within the leptomeninges, neuronal heterotopias, hypoplasia of nerve tracts, hydrocephalus, and, occasionally, encephalocele. Ocular abnormalities include microphthalmia, cataract, immature anterior chamber angle, retinal dysplasia with or without retinal detachment, persistent hyperplastic primary vitreous, optic nerve hypoplasia, and coloboma. Skeletal muscle findings include fiber splitting, variable fiber size, and endomysial fibrosis. Recent evidence has shown that COD-MD syndrome may be identical to the Walker-Warburg (also known as Warburg) syndrome. Fukuyama congenital muscular dystrophy is similar to the COD-MD and Walker-Warburg syndromes, although the ocular manifestations are less severe. We report the histopathologic findings in two siblings with multiple features of COD-MD syndrome.

Retinal dysplasia and agyria without cortical lamination are the constant findings in this autosomal recessive syndrome. There may also be anterior chamber malformations, cataract, and microphthalmos. Brain autopsies have shown a variety of associated malformations such as posterior encephalocele, Arnold-Chiari malformation, agenesis of the septum pellucidum and of the corpus callosum, agenesis of the vermis and hypoplasia of the cerebellum. Muscular dystrophy is probably present in most of these patients. Within the last few years, over 20 cases with a complete autopsy have been described. The syndrome should be differentiated from other syndromes with retinal non-attachment and retinal dysplasia, and from syndromes with hydrocephalus or encephalocele without these ocular features.

Two siblings are reported who appear to have an autosomal recessive disorder of eye and central nervous system anomalies. The findings in fourteen previously described and similarly affected patients are summarized. Ocular anomalies include microphthalmos, megalocornea, the Peter anomaly, cataract, coloboma, persistent hyperplastic primary vitreous, and retinal detachment with retinal dysplasia. Central nervous system malformations include agyria-pachygyria, cerebellar dysplasia, encephalocele, Dandy-Walker cyst, and hydrocephalus. We suggest that this disorder be known as Warburg syndrome.

Familial occurrence of cerebral malformations with muscular dystrophy was described by Fukuyama as congenital cerebromuscular dystrophy. We have observed a new syndrome belonging to the same group in three siblings. These syndromes differ in the degree of CNS involvement and abnormalities in the eye. The main clinical characteristics of our cohort were dysmorphic face, hypotonia, areflexia, failure to thrive, corneal opacity, cataract, dysgenesis of the anterior chamber of the eye, and death within the 1st year of life. Hydrocephalus and agyria were verified by computed tomography. Neuropathologic examination demonstrated malformations of the CNS. The agyric hemispheres with polymicrogyria in several cortical segments and severe cortical disorganization in other segments represented the principal anomaly. Congenital muscular dystrophy was also found. The CNS anomalies demonstrated a long-lasting pathologic process extending to involve the eye and muscle, which is most likely an inborn error of metabolism with autosomal recessive inheritance.

The Walker-Warburg syndrome (WWS) is an autosomal recessive disease entity within the framework of "cerebro-ocular-muscular syndromes". The gene locus is still undetected. Its diagnostic criteria have been firmly established in the literature on newborns or infants affected with the disease. However, a diagnosis of severe pathologic conditions must often be made on the basis of ultrasound examination at a fetal age. It is therefore necessary to examined whether the diagnostic criteria are sufficient to warrant a diagnosis at the fetal stage. We here report on a new family affected with WWS. Two elder siblings had presented with epileptic seizures, eye abnormalities as well as multiple skeletal dysplasias (the latter finding in the first child only) in the neonatal period, and died in their first years. Postmortem examination of the second child revealed type II lissencephaly, buphthalmos, and undifferentiated retina with rigid retinal folds. Skeletal muscle tissue was not examined. In a sibling fetus, bilateral cataract was detected in the 17th gestational week by ultrasonographic examination. Postmortem examination in the 23rd gestational week revealed type II lissencephaly and bilateral cataract. Skeletal muscle was normal. Taken together, all siblings were diagnosed as Walker-Warburg syndrome. In the fetal case, prenatal diagnosis could only be made with confidence against a background of a positive family history.

A 10-year-old boy presented with a severe and diffuse mosaic skin hypopigmentation running (in narrow bands) along the lines of Blaschko associated with mosaic areas of alopecia, facial dysmorphism with midface hypoplasia, bilateral punctate cataract, microretrognathia, short neck, pectus excavatum, joint hypermobility, mild muscular hypotonia, generalized seizures, and mild mental retardation. Cranial magnetic resonance imaging revealed hypoplastic corpus callosum (primarily posterior), subcortical band heterotopia, and diffuse subcortical, periventricular cystic-like lesions. Similar dysmorphic features were observed in the child's mother, but with no imaging abnormalities. The facial phenotype coupled with the cysts in the brain was strongly reminiscent of the oculocerebrorenal Lowe syndrome. Full chromosome studies in the parents and the proband and mutation analysis on peripheral blood lymphocytes (and on skin cultured fibroblasts from affected and unaffected skin areas in the child) in the genes for subcortical band heterotopia (DCX (Xq22.3-q23)], lissencephaly (PAFAH1B1, alias LIS1, at 17p13.3), and oculocerebrorenal syndrome of Lowe (OCRL at Xq23-q24)] were unrevealing. This constellation of multiple congenital anomalies including skin hypopigmentation and eye, musculoskeletal, and nervous system abnormalities was sufficiently characterized to be regarded as a novel example of pigmentary mosaicism of the Ito type (i.e., hypomelanosis of Ito).

Mutations in DYNC1H1, the gene encoding the largest cytoplasmic dynein, have been associated with a wide spectrum of neurodegenerative disorders. In this study, we describe a child in whom a novel de novo likely pathogenic variant in the motor domain of DYCN1H1 was identified through whole exome sequencing. The affected child presented with severe neurological symptoms and more extensive cortical malformations compared to previously reported cases with mutations in this gene, including diffuse pachygyria-lissencephaly and bilateral symmetric subcortical gray matter heterotopia. A more distinct aspect of the phenotype in this child is the presence of cataract in infancy. So far, only acquired bilateral cataract in adulthood has been described in this disorder in a patient with a much milder neurological phenotype. These findings could extend the phenotype associated with defective DYNC1H1 and suggest a possible important role in human ocular development.
