Low match AUTISM, SUSCEPTIBILITY TO, X-LINKED 4; AUTSX4

Autism, the prototypic pervasive developmental disorder (PDD), is usually apparent by 3 years of age. It is characterized by a triad of limited or absent verbal communication, a lack of reciprocal social interaction or responsiveness, and restricted, stereotypical, and ritualized patterns of interests and behavior (Bailey et al., 1996; Risch et al., 1999). 'Autism spectrum disorder,' sometimes referred to as ASD, is a broader phenotype encompassing the less severe disorders Asperger syndrome (see ASPG1; {608638}) and pervasive developmental disorder, not otherwise specified (PDD-NOS). 'Broad autism phenotype' includes individuals with some symptoms of autism, but who do not meet the full criteria for autism or other disorders. Mental retardation coexists in approximately two-thirds of individuals with ASD, except for Asperger syndrome, in which mental retardation is conspicuously absent (Jones et al., 2008). Genetic studies in autism often include family members with these less stringent diagnoses (Schellenberg et al., 2006).Levy et al. (2009) provided a general review of autism and autism spectrum disorder, including epidemiology, characteristics of the disorder, diagnosis, neurobiologic hypotheses for the etiology, genetics, and treatment options.

Low match CATARACT 21, MULTIPLE TYPES; CTRCT21

Mutations in the MAF gene have been found to cause multiple types of cataract, which have been described as cortical pulverulent, lamellar, nuclear, nuclear pulverulent, nuclear stellate, anterior polar, anterior subcapsular, posterior subcapsular, and cerulean. In some cases, the cataracts are of juvenile onset.The preferred title of this entry was formerly 'Cataract, Pulverulent, Juvenile-Onset,' with an 'Included' title/symbol of 'Cataract, Congenital, Cerulean Type, 4; CCA4.'

Low match INTELLECTUAL DEVELOPMENTAL DISORDER WITH CARDIAC ARRHYTHMIA; IDDCA

Intellectual developmental disorder with cardiac arrhythmia is an autosomal recessive multisystem disorder characterized by delayed psychomotor development, severe intellectual disability with poor or absent speech, and bradycardia and/or cardiac sinus arrhythmias. Additional features include visual abnormalities, seizures, hypotonia, and gastric reflux (summary by Lodder et al., 2016).

Low match HYPOTONIA, INFANTILE, WITH PSYCHOMOTOR RETARDATION; IHPMR

Severe hypotonia-psychomotor developmental delay-strabismus-cardiac septal defect syndrome is a rare, genetic, non-dystrophic congenital myopathy disorder characterized by a neonatal-onset of severe generalized hypotonia associated with mild psychomotor delay, congenital strabismus with abducens nerve palsy, and atrial and/or ventricular septal defects. Cryptorchidism is commonly reported in male patients and muscle biopsy typically reveals increased variability in muscle fiber size.

IMDDHH is a multisystem disorder characterized by immunodeficiency, mildly delayed psychomotor development, poor overall growth from infancy, and hypohomocysteinemia. Additional features, such as congenital heart defects and liver involvement, are more variable (summary by Huppke et al., 2017).

Low match EPILEPTIC ENCEPHALOPATHY, EARLY INFANTILE, 27; EIEE27

EIEE27 is an autosomal dominant neurodevelopmental disorder characterized by delayed psychomotor development and intellectual disability of variable severity associated with early-onset seizures. Additional features may include hypotonia, abnormal movements, such as dystonia, and autistic features. Some patients may have structural malformations of cortical development on brain imaging. The phenotype is highly variable and reflects a spectrum of neurodevelopmental abnormalities that range from mild intellectual disability without seizures to an encephalopathy (summary by Platzer et al., 2017).For a general phenotypic description and a discussion of genetic heterogeneity of EIEE, see EIEE1 (OMIM ).
