Hereditary hyperferritinemia with congenital cataracts is characterized by the association of early onset (although generally absent at birth) cataract with persistently raised plasma ferritin concentrations in the absence of iron overload.

Autosomal recessive spastic paraplegia type 69 is a rare, complex hereditary spastic paraplegia disorder characterized by infantile onset of progressive lower limb spasticity, global developmental delay, hyperreflexia, clonus and extensor plantar reflexes, associated with dysarthria, intellectual disability, cataracts and hearing impairment.

Early infantile epileptic encephalopathy-35 is an autosomal recessive neurodegenerative disorder characterized by onset of seizures in the first months of life associated with essentially no normal development. Brain imaging shows a characteristic pattern consistent with lack of myelination of early structures, including the posterior limb of the internal capsule, brainstem tracts, and tracts to the primary visual and motor cortices. Many patients die in early childhood (summary by Kevelam et al., 2015)For a general phenotypic description and a discussion of genetic heterogeneity of EIEE, see {308350}.

• Seizures
• Global developmental delay
• Generalized hypotonia
• Microcephaly

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.

Usher syndrome is a clinically and genetically heterogeneous autosomal recessive disorder characterized by sensorineural hearing deficiencies at birth and later development of progressive retinitis pigmentosa (RP). It is the most frequent cause of combined deafness and blindness in adults and affects 3 to 6% of children born with hearing impairment. In brief, patients with Usher syndrome type II have mild hearing impairment with normal vestibular responses. Type II is the most common of the 3 Usher syndromes (Eudy et al., 1998).See {276900} for clinical characterization of Usher syndrome types I, II, and III.For a discussion of genetic heterogeneity of Usher syndrome type II, see USH2A (OMIM ).

USHER SYNDROME TYPE 2 Is also known as ush2

• Ataxia
• Nystagmus
• Sensorineural hearing impairment

Microcephalic primordial dwarfism due to ZNF335 deficiency is characterized by severe antenatal microencephaly, simplified gyration, agenesis of the corpus callosum, absence of basal ganglia (very rare), pontocerebellar atrophy and involvement of the white matter with secondary cerebral atrophy. Congenital cataract, choanal atresia, multiple arthrogryposis and spastic tetraparesis can occur.

Microcephaly and chorioretinopathy-2 is an autosomal recessive developmental disorder characterized by delayed psychomotor development, visual impairment, and short stature (summary by Martin et al., 2014).For a discussion of genetic heterogeneity of microcephaly and chorioretinopathy, see MCCRP1 (OMIM ).

Cerebrooculofacioskeletal syndrome is a severe, progressive neurologic disorder characterized by prenatal onset of arthrogryposis, microcephaly, and growth failure. Postnatal features include severe developmental delay, congenital cataracts (in some), and marked UV sensitivity of the skin. Survival beyond 6 years of age is rare. COFS represents the severe end of the spectrum of disorders caused by mutations in nucleotide excision repair (NER) genes, with Cockayne syndrome and xeroderma pigmentosum being milder NER-related phenotypes (summary by Drury et al., 2014).For a phenotypic description and a discussion of genetic heterogeneity of cerebrooculofacioskeletal syndrome, see COFS1 (OMIM ).

• Microcephaly
• Growth delay
