Intellectual developmental disorder with abnormal behavior, microcephaly and short stature (IDDABS), (OMIM# 618342) is an autosomal recessive condition described as developmental delay, poor or absent speech, intellectual disability, short stature, mild to progressive microcephaly, delayed psychomotor development, hyperactivity, seizure, along with mild to swear aggressive behavior. Homozygous frameshift mutation in Pseudouridine Synthase 7, Putative; (PUS7) OMIM# 616,261 NM_019042.3 and splice acceptor variants in Alpha-Aminoadipic Semialdehyde Synthase; (AASS) OMIM# 605,113 NM_005763.

Article Synopsis
  • Epilepsy is common in children, but little research exists on its effect on their oral health; this study aimed to assess that impact in Jeddah, Saudi Arabia, using mothers' perceptions.
  • The study included 96 children aged 2-18 with epilepsy; over half rated their dental status as bad, and the majority expressed a need for dental care.
  • Key risk factors for poor dental status included cerebral palsy, motor disability, referral from a pediatric neurology clinic, and irregular tooth brushing, while being perceived as overweight decreased the risk; targeted dental interventions are necessary for children with motor impairments.

PGAP2 (Post-GPI Attachment to Proteins 2) gene is involved in lipid remodeling steps of Glycosylphosphatidylinositol (GPI)-anchor maturation. At the surface of the cell this gene is required for proper expression of GPI-anchored proteins. Hyperphosphatasia with mental retardation syndrome-3 is an autosomal recessive disorder usually characterized by severe mental retardation.

Background: Epilepsy is genetically complex but common brain disorder of the world affecting millions of people with almost of all age groups. Novel Copy number variations (CNVs) are considered as important reason for the numerous neurodevelopmental disorders along with intellectual disability and epilepsy. DNA array based studies contribute to explain a more severe clinical presentation of the disease but interoperation of many detected CNVs are still challenging.

Cerebral palsy (CP) is a common chronic motor disorder with associated cognitive, communicative, and seizure disorders. Children with CP have a higher risk of dental problems creating significant morbidity that can further affect their wellbeing and negatively impact their quality of life. Screening for dental disease should be part of the initial assessment of any child with CP.

Dravet syndrome (DS) is a severe epilepsy syndrome characterized by early onset of multiple types of seizures. We report the first case of reflex seizures triggered by diaper change in a girl at 9 months old and 2 years old with a mutation in the SCN1A gene causing DS. Reflex seizures have been reported in patients with DS provoked by increased body temperature or visual stimulation.

Lennox-Gastaut syndrome (LGS) is a severe pediatric epilepsy syndrome characterized by mixed seizures, cognitive decline, and generalized slow (<3 Hz) spike wave discharges on electroencephalography. Atonic seizures result in dangerous drop attacks with risks of injury and impairment of the quality of life. The seizures are frequently resistant to multiple antiepileptic (AED) drugs.

Background: Epilepsy is genetically complex neurological disorder affecting millions of people of different age groups varying in its type and severity. Copy number variants (CNVs) are key players in the genetic etiology of numerous neurodevelopmental disorders and prior findings also revealed that chromosomal aberrations are more susceptible against the pathogenesis of epilepsy. Novel technologies, such as array comparative genomic hybridization (array-CGH), may help to uncover the pathogenic CNVs in patients with epilepsy.
