Barstein, Jamie; Jeste, Shafali; Saravanapandian, Vidya; Hyde, Carly; Distefano, Charlotte – American Journal on Intellectual and Developmental Disabilities, 2021
Duplication of chromosome 15q11.2-q13.1 (dup15q syndrome) results in hypotonia, intellectual disability (ID), and autism symptomatology. Clinical electroencephalography has shown abnormal sleep physiology, but no studies have characterized sleep behaviors. The present study used the Children's Sleep Habits Questionnaire (CSHQ) in 42 people with…

Edens, Anna C.; Lyons, Michael J.; Duron, Reyna M.; DuPont, Barbara R.; Holden, Kenton R. – Developmental Medicine & Child Neurology, 2011
We present two phenotypically similar females with Xp duplication who have autism and epilepsy. Case 1 is a 14-year-old Honduran female with autism and medically refractory complex partial, secondarily generalized epilepsy. Case 2 is a 3-year-old Austrian female with autism and medically refractory complex partial epilepsy. Both patients also…

Watson, Shelley Lynn; Richards, Deborah A.; Miodrag, Nancy; Fedoroff, J. Paul – Intellectual and Developmental Disabilities, 2012
Specific genetic syndromes affect individuals' sexual development, experiences, and fertility. Individuals with specific syndromes can also display inappropriate sexual behavior resulting from vulnerabilities presented by their genetic makeup. Using clinical case studies, we discuss the specific impact that Down, Prader-Willi, and Williams…

Battaglia, Agatino; Filippi, Tiziana; South, Sarah T.; Carey, John C. – Developmental Medicine & Child Neurology, 2009
To define the spectrum of epilepsy in Wolf-Hirschhorn syndrome (WHS) better, we studied 87 patients (54 females, 33 males; median age 5.6 years; age range 1-25.6 years) with confirmed 4p16.3 deletion. On the basis of clinical charts, we retrospectively analyzed the evolution of the electroencephalogram (EEG) findings and seizures. Epilepsy…

Gasca, C. Brun; Obiols, J. E.; Bonillo, A.; Artigas, J.; Lorente, I.; Gabau, E.; Guitart, M.; Turk, J. – Journal of Intellectual Disability Research, 2010
Background: Angelman syndrome (AS) is a neurodevelopmental disorder usually caused by an anomaly in the maternally inherited chromosome 15. The main features are severe intellectual disability, speech impairment, ataxia, epilepsy, sleep disorder and a behavioural phenotype that reportedly includes happy disposition, attraction to/fascination with…

Didden, Robert; Sigafoos, Jeff; Korzilius, Hubert; Baas, Astrid; Lancioni, Giulio E.; O'Reilly, Mark F.; Curfs, Leopold M. G. – Journal of Applied Research in Intellectual Disabilities, 2009
There are only a few studies that have attempted to systematically document the communicative forms and functions in the repertoires of individuals with Angelman syndrome (AS). In the present study, we sent the "Inventory of Potential Communicative Acts" (IPCA) (Sigafoos et al. 2000a,b) to 136 families of children with AS. The IPCA aims to provide…

Ehninger, D.; de Vries, P. J.; Silva, A. J. – Journal of Intellectual Disability Research, 2009
Background: Tuberous sclerosis (TSC) is a multi-system disorder caused by heterozygous mutations in the "TSC1" or "TSC2" gene and is often associated with neuropsychiatric symptoms, including intellectual disability, specific neuropsychological deficits, autism, other behavioural disorders and epilepsy. Method: Here, we review evidence from animal…

O'Rourke, Declan J.; Ryan, Stephanie; Salomons, Gajja; Jakobs, Cornelis; Monavari, Ahmad; King, Mary D. – Developmental Medicine & Child Neurology, 2009
Guanidinoacetate methyltransferase (GAMT) deficiency is a disorder of creatine biosynthesis, characterized by early-onset learning disability and epilepsy in most affected children. Severe expressive language delay is a constant feature even in the mildest clinical phenotypes. We report the clinical, biochemical, imaging, and treatment data of two…

Bahi-Buisson, Nadia; Nectoux, Juliette; Rosas-Vargas, Haydee; Milh, Mathieu; Boddaert, Nathalie; Girard, Benoit; Cances, Claude; Ville, Dorothee; Afenjar, Alexandra; Rio, Marlene; Heron, Delphine; Morel, Marie Ange N'Guyen; Arzimanoglou, Alexis; Philippe, Christophe; Jonveaux, Philippe; Chelly, Jamel; Bienvenu, Thierry – Brain, 2008
Mutations in the human X-linked cyclin-dependent kinase-like 5 ("CDKL5") gene have been shown to cause infantile spasms as well as Rett syndrome (RTT)-like phenotype. To date, less than 25 different mutations have been reported. So far, there are still little data on the key clinical diagnosis criteria and on the natural history of…

Taylor, Isabella; Berkovic, Samuel F.; Kivity, Sara; Scheffer, Ingrid E. – Brain, 2008
The early and late benign occipital epilepsies of childhood (BOEC) are described as two discrete electro-clinical syndromes, eponymously known as Panayiotopoulos and Gastaut syndromes. Our aim was to explore the clinical features, classification and clinical genetics of these syndromes using twin and multiplex family studies to determine whether…

Ian; Wallace, Geoffrey; Kivity, Sara; Lev, Dorit; Lerman-Sagie, Tally; Derry, Christopher P.; Korczyn, Amos D.; Gecz, Jozef; Mulley, John C.; Berkovic, Samuel F. – Brain, 2008
Epilepsy and Mental Retardation limited to Females (EFMR) which links to Xq22 has been reported in only one family. We aimed to determine if there was a distinctive phenotype that would enhance recognition of this disorder. We ascertained four unrelated families (two Australian, two Israeli) where seizures in females were transmitted through…
