To understand the genetic heterogeneity underlying developmental delay, we compared copy number variants (CNVs) in 15,767 children with intellectual disability and various congenital defects (cases) to CNVs in 8,329 unaffected adult controls. We estimate that ∼14.2% of disease in these children is caused by CNVs >400 kb. We observed a greater enrichment of(More)
In 1995, a consensus statement was published for the purpose of summarizing the salient clinical features of Angelman syndrome (AS) to assist the clinician in making a timely and accurate diagnosis. Considering the scientific advances made in the last 10 years, it is necessary now to review the validity of the original consensus criteria. As in the original(More)
Familial idiopathic basal ganglia calcification (IBGC) or Fahr's disease is a rare neurodegenerative disorder characterized by calcium deposits in the basal ganglia and other brain regions, which is associated with neuropsychiatric and motor symptoms. Familial IBGC is genetically heterogeneous and typically transmitted in an autosomal dominant fashion. We(More)
PURPOSE The primary goal of this case study was to describe the speech, prosody, and voice characteristics of a mother and daughter with a breakpoint in a balanced 7;13 chromosomal translocation that disrupted the transcription gene, FOXP2 (cf. J. B. Tomblin et al., 2005). As with affected members of the widely cited KE family, whose communicative disorders(More)
PURPOSE The aims of this study were (a) to locate the breakpoints of a balanced translocation (7;13) within a mother (B) and daughter (T); (b) to describe the language and cognitive skills of B and T; and (c) to compare this profile with affected family members of the KE family who have a mutation within FOXP2. METHOD The breakpoint locations for T and B(More)
We use GPS displacements collected in the 15 months after the 1999 Chi-Chi, Taiwan earthquake (M w 7.6) to evaluate whether post-seismic deformation is better explained by afterslip or viscoelastic relaxation of the lower crust and upper mantle. We find that all viscoelas-tic models tested fail to fit the general features in the post-seismic GPS(More)
To further delineate the clinical and developmental features of Angelman syndrome, we collected data through three sources of information: (1) physical examinations; (2) laboratory data and family questionnaire data of affected individuals; and (3) literature review. The questionnaire data describes a generally normal prenatal and birth history. Feeding(More)
This report is a meeting summary of the 2010 Angelman Syndrome Foundation's scientific symposium on the neuroscience of UBE3A. Angelman syndrome is characterized by loss of speech, severe developmental delay, seizures, and ataxia. These core symptoms are caused by maternal allele disruptions of a single gene-UBE3A. UBE3A encodes an E3 ubiquitin ligase that(More)
The Angelman syndrome is clinically delineated by the combination of seizures, absent speech, hypermotoric and ataxic movements and certain remarkable behaviors. Those with the syndrome have a predisposition toward apparent happiness and paroxysms of laughter, and this finding helps distinguish Angelman syndrome from other ones involving severe(More)
