We describe the inherited folate sensitive fragile site, fra(2)(q13), in three unrelated mentally retarded children, two of them with different forms of epilepsy. Fra(2)(q13) was detected in one healthy sib of one of the probands. Except for one cell in one of the fathers, fra(2)(q13) could not be detected in any of the six parents, who were repeatedly studied using methods known to induce frag...
Although the etiology of autism remains largely unknown, cytogenetic and genetic studies have implicated maternal copy number gains of 15q11-q13 in 1-3% of autism cases. In order to understand how maternal 15q duplication leads to dysregulation of gene expression and altered chromatin interactions, we used microcell-mediated chromosome transfer to generate a novel maternal 15q duplication model...
Cytogenetic abnormalities in the Prader-Willi/Angelman syndrome (PWS/AS) critical region have been described in individuals with autism. Maternal duplications and linkage disequilibrium in families with autism suggest the existence of a susceptibility locus at 15q11-q13. Here, we describe a 6-year-old girl diagnosed with autism, developmental delay, and delayed expressive and receptive language...
BACKGROUND Maternally derived duplications of the 15q11-q13 region are the most frequently reported chromosomal aberrations in autism spectrum disorders (ASD). Prader-Willi and Angelman syndromes, caused by 15q11-q13 deletions or abnormal methylation of imprinted genes, are also associated with ASD. However, the prevalence of these disorders in ASD is unknown. The aim of this study was to asses...
