Lumish, Heidi S.; Wynn, Julia; Devinsky, Orrin; Chung, Wendy K. – Journal of Autism and Developmental Disorders, 2015
Whole exome sequencing (WES) has been utilized with increasing frequency to identify mutations underlying rare diseases. Autism spectrum disorders (ASD) and intellectual disability (ID) are genetically heterogeneous, and novel genes for these disorders are rapidly being identified, making these disorders ideal candidates for WES. Here we report a…

Zablotsky, Benjamin; Black, Lindsey I. – National Center for Health Statistics, 2020
Objective: This report examines the prevalence of developmental disabilities among children in both rural and urban areas as well as service utilization among children with developmental issues in both areas. Methods: Data from the 2015-2018 National Health Interview Survey (NHIS) were used to examine the prevalence of 10 parent- or…

Angkustsiri, Kathleen; Krakowiak, Paula; Moghaddam, Billur; Wardinsky, Terrance; Gardner, Jerald; Kalamkarian, Nareg; Hertz-Picciotto, Irva; Hansen, Robin L. – Autism: The International Journal of Research and Practice, 2011
Objective: There is clinical heterogeneity among the autism spectrum disorders (ASD). The presence of dysmorphology (minor physical anomalies; MPAs) is one possible tool for defining a clinically relevant subset in ASD. This study employs an adaptation of Miles and Hillman's (2000) classifications by using photographs to identify a subgroup with…

Stacy, Maria E.; Zablotsky, Benjamin; Yarger, Heather A.; Zimmerman, Andrew; Makia, Barraw; Lee, Li-Ching – Autism: The International Journal of Research and Practice, 2014
This study investigated differences in co-occurring diagnoses made in females compared to males with autism spectrum disorders in 913 children (746 males and 167 females) living in the United States with a current autism spectrum disorder diagnosis identified via caregiver-reported data from the National Survey of Children's Health 2007. The…

Berry-Kravis, Elizabeth; Raspa, Melissa; Loggin-Hester, Lisa; Bishop, Ellen; Holiday, David; Bailey, Donald B., Jr. – American Journal on Intellectual and Developmental Disabilities, 2010
A national survey of caregivers of individuals with fragile X syndrome addressed characteristics of epilepsy and co-occurring conditions. Of the 1,394 individuals (1,090 males and 304 females) with the full mutation, 14% of males and 6% of females reported seizures. Seizures were more often partial, began between ages 4 and 10 years, and were…

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…

We studied seven children with CNS folate deficiency (CFD). All cases exhibited psychomotor retardation, regression, cognitive delay, and dyskinesia; six had seizures; four demonstrated neurological abnormalities in the neonatal period. Two subjects had profound neurological abnormalities that precluded formal behavioral testing. Five subjects…

Walz, Nicolay Chertkoff – Journal of Autism and Developmental Disorders, 2007
Research examining autistic symptoms in Angelman syndrome (AS) is limited. The goal of this study was to further characterize the nature of stereotyped behaviors, social interaction deficits, and developmental disturbances in individuals with AS. Parents of 248 individuals between the ages of 3 and 22 completed a survey of autistic symptomatology…
