BACKGROUND Genomic deletions and duplications are important in the pathogenesis of diseases, such as cancer and mental retardation, and have recently been shown to occur frequently in unaffected individuals as polymorphisms. Affymetrix GeneChip whole genome sampling analysis (WGSA) combined with 100 K single nucleotide polymorphism (SNP) genotyping arrays(More)
BACKGROUND Clinical laboratories are adopting array genomic hybridization as a standard clinical test. A number of whole genome array genomic hybridization platforms are available, but little is known about their comparative performance in a clinical context. METHODS We studied 30 children with idiopathic MR and both unaffected parents of each child using(More)
BACKGROUND Array genomic hybridization is being used clinically to detect pathogenic copy number variants in children with intellectual disability and other birth defects. However, there is no agreement regarding the kind of array, the distribution of probes across the genome, or the resolution that is most appropriate for clinical use. RESULTS We(More)
BACKGROUND Mutations of TCF4, which encodes a basic helix-loop-helix transcription factor, cause Pitt-Hopkins syndrome (PTHS) via multiple genetic mechanisms. TCF4 is a complex locus expressing multiple transcripts by alternative splicing and use of multiple promoters. To address the relationship between mutation of these transcripts and phenotype, we(More)
Mutations in SCO2, a metallochaperone involved in mitochondrial copper delivery, are associated with early onset, fatal hypertrophic cardiomyopathy. All reported patients carry at least one copy of the common 1541G>A (E140K) mutation. Whereas patients with one copy of the E140K allele, in combination with a more deleterious mutation, follow a severe(More)
