intellectual disability and hearing impairment

Mark D Simms
Most neurodevelopmental disorders are defined by their clinical symptoms and many disorders share common features. Recently there has been an increase in the number of children diagnosed with autism spectrum disorder, although concerns have been raised about the accuracy of the reported prevalence rates. This article reviews the essential features of autism spectrum disorder and describes other conditions that may include similar symptoms that may be misdiagnosed as autism spectrum disorder (primary communication disorders, anxiety disorders, attachment disorders, intellectual disability, vision and hearing impairment, and normal variations)...

Van Maldergem syndrome (VMS) is a very rare syndrome that was first described in 1992. The main features of this syndrome comprise intellectual disability, blepharo-naso-facial malformation, and hand anomalies. Almost all nine described patients have been shown to be affected by conductive hearing impairment attributed to microtia, and atresia of the outer ear canal. Here, we present a VMS patient with congenital malformations of the middle ear as the main reason for severe conductive bilateral hearing impairment...

Postaxial polydactyly (PAP) is one of the most common congenital malformations observed in the general population. However, it can also occur as part of a syndrome. Unbiased genetic screening techniques such as exome sequencing are highly appropriate methods to provide a molecular diagnosis in patients with polydactyly due to the large number of mutated genes associated with it. The present study describes a consanguineous family of Pakistani origin with PAP, speech impairment, hearing impairment of variable degree, and proportionate short stature with no prominent intellectual disability or ophthalmological abnormalities...

Arts syndrome is characterized by early-onset hypotonia, ataxia, intellectual disability, sensorineural hearing impairment, progressive optic atrophy, and a tendency to develop infections. Arts syndrome is an X-linked disorder caused by a loss-of-function mutation in the PRPS1 gene, which encodes phosphoribosylpyrophosphate synthetase 1. Only three families have been reported. Here, we report another family with Arts syndrome. The initial symptoms of the 1-year-old proband were hypotonia and ataxia, worsening recurrent infection-triggered muscle weakness, motor and intellectual developmental delay, and hearing loss...

BACKGROUND: Congenital cytomegalovirus (CMV) infection causes various neurological sequelae. However, most infected infants are asymptomatic at birth, and retrospective diagnosis is difficult beyond the neonatal period. OBJECTIVE: This study aimed to investigate the aspects of neurological sequelae associated with asymptomatic congenital CMV infection. METHODS: We retrospectively analyzed 182 patients who were suspected of having asymptomatic congenital CMV infection with neurological symptoms in Japan...

BACKGROUND: The results of numerous studies indicate that people with disabilities seek more healthcare than those who are not disabled, particularly for conditions such as chronic kidney disease, cardiovascular disease, and obesity. However, little is known about the incidence of impaired kidney function and its associated factors among adults with disabilities in Taiwan. PURPOSE: The aim of this study was to explore the prevalence and factors associated with impaired kidney function among adults with disabilities...

PURPOSE: Bosch-Boonstra-Schaaf optic atrophy syndrome (BBSOAS) is an autosomal-dominant disorder characterized by optic atrophy and intellectual disability caused by loss-of-function mutations in NR2F1. We report 20 new individuals with BBSOAS, exploring the spectrum of clinical phenotypes and assessing potential genotype-phenotype correlations. METHODS: Clinical features of individuals with pathogenic NR2F1 variants were evaluated by review of medical records. The functional relevance of coding nonsynonymous NR2F1 variants was assessed with a luciferase assay measuring the impact on transcriptional activity...

CHARGE syndrome (MIM#214800) (Coloboma, Heart defect, Atresia of choanae, Retarded growth and development, Genital hypoplasia, Ear abnormalities/deafness) is caused by heterozygous mutation of CHD7 transmitted in an autosomal dominant manner. In this report, we describe a patient with bilateral hearing impairment, unusually-shaped ears, no intellectual disability and a patent ductus arteriosus. Further investigation showed abnormal semicircular canals and the presence of olfactory bulbs. He does not fulfill the Blake or the Verloes criteria for CHARGE...

Attentional, visuospatial, and social cognition deficits have a negative impact on children's adaptative and social competences and, as a result, on their ability to achieve a normal functioning and behavior. Until now and despite the frequency of those deficits, there is a lack of children's specific cognitive remediation tools specifically dedicated to attentional and visuospatial areas. The «Cognitus & Moi» program involves a variety of exercises in a paper and/or pencil (n = 30) or a computerized format (n = 29) and a strategy coaching approach...

OBJECTIVE: The lysosomal storage disease alpha-mannosidosis is caused by the deficiency of the lysosomal acid hydrolase alpha-mannosidase (LAMAN) leading to lysosomal accumulation of neutral mannose-linked oligosaccharides throughout the body, including the brain. Clinical findings in alpha-mannosidosis include skeletal malformations, intellectual disabilities and hearing impairment. To date, no curative treatment is available. We previously developed a beneficial enzyme replacement therapy (ERT) regimen for alpha-mannosidase knockout mice, a valid mouse model for the human disease...

BACKGROUND: Limited evidence suggests that people with ID (ID) are overrepresented in prisons although prevalence rates of ID among prisoners vary significantly across studies, making it difficult to identify prevalence and assess existing need. METHOD: A systematic review of relevant literature was conducted, and results were organized and compared in relation to study aims, design, measures used to screen for ID, sample, limitations and key findings. RESULTS: Existing international data suggest a prevalence of prisoners with ID between 7 and 10%...

Interstitial deletions of the long arm of chromosome 6 are rare. Clinically, these deletions are considered to be part of a unique microdeletion syndrome associated with intellectual disability and speech impairment, typical dysmorphic features, structural anomalies of the brain, microcephaly, and non-specific multiple organ anomalies. The critical region for the interstitial 6q microdeletion phenotype was mapped to 6q24-6q25, particularly the 6q25.3 region containing the genes ARID1B and ZDHHC14. It has been hypothesized that haploinsufficiency of these genes impairs normal development of the brain and is responsible for the phenotype...
