Transition of the double-stranded DNA molecule to its two single strands, DNA denaturation or melting, has been used for many years to study DNA structure and composition. Recent technological advances have improved the potential of this technology, especially to detect variants in the DNA sequence. Sensitivity and specificity were increased significantly(More)
We identified de novo truncating mutations in ARID1B in three individuals with Coffin-Siris syndrome (CSS) by exome sequencing. Array-based copy-number variation (CNV) analysis in 2,000 individuals with intellectual disability revealed deletions encompassing ARID1B in 3 subjects with phenotypes partially overlapping that of CSS. Taken together with(More)
Streptococcus agalactiae (Group B Streptococcus; GBS) is a major contributor to obstetric and neonatal bacterial sepsis. Serotype III strains cause the majority of late-onset sepsis and meningitis in babies, and thus appear to have an enhanced invasive capacity compared with the other serotypes that cause disease predominantly in immunocompromised pregnant(More)
Terminal osseous dysplasia (TOD) is an X-linked dominant male-lethal disease characterized by skeletal dysplasia of the limbs, pigmentary defects of the skin, and recurrent digital fibroma with onset in female infancy. After performing X-exome capture and sequencing, we identified a mutation at the last nucleotide of exon 31 of the FLNA gene as the most(More)
De novo germline variants in several components of the SWI/SNF-like BAF complex can cause Coffin-Siris syndrome (CSS), Nicolaides-Baraitser syndrome (NCBRS), and nonsyndromic intellectual disability. We screened 63 patients with a clinical diagnosis of CSS for these genes (ARID1A, ARID1B, SMARCA2, SMARCA4, SMARCB1, and SMARCE1) and identified pathogenic(More)
Keratosis Follicularis Spinulosa Decalvans (KFSD) is a rare genetic disorder characterized by development of hyperkeratotic follicular papules on the scalp followed by progressive alopecia of the scalp, eyelashes, and eyebrows. Associated eye findings include photophobia in childhood and corneal dystrophy. Due to the genetic and clinical heterogeneity of(More)
The detection of quantitative changes in genomic DNA, i.e. deletions and duplications or Copy Number Variants (CNVs), has recently gained considerable interest. First, detailed analysis of the human genome showed a surprising amount of CNVs, involving thousands of genes. Second, it was realised that the detection of CNVs as a cause of genetic disease was(More)
PURPOSE Truncating mutations in the maternally imprinted, paternally expressed gene MAGEL2, which is located in the Prader-Willi critical region 15q11-13, have recently been reported to cause Schaaf-Yang syndrome, a Prader-Willi-like disease that manifests as developmental delay/intellectual disability, hypotonia, feeding difficulties, and autism spectrum(More)
Congenital limb malformations are the second most common birth defects observed in infants. Split hand foot malformation (SHFM), also known as central ray deficiency, ectrodactyly and cleft hand/foot, occurs isolated or in combination with other malformations. We report on a male patient with SHFM, tetralogy of Fallot and a clinical phenotype suggestive of(More)
Aarskog-Scott syndrome (ASS) is a rare disorder with characteristic facial, skeletal, and genital abnormalities. Mutations in the FGD1 gene (Xp11.21) are responsible for ASS. However, mutation detection rates are low. Here, we report a family with ASS where conventional Sanger sequencing failed to detect a pathogenic change in FGD1. To identify the(More)
