Next-generation sequencing (NGS) has been revolutionary for the clinical diagnostics field. With its high throughput sequencing power and plummeting cost, it has been increasingly used in clinical labs. Instead of testing the candidate genes one at a time by Sanger sequencing, now a lab can test a group of candidate genes at the same time using the NGS method. For example, many clinical labs no...
Genotyping arrays are a cost effective approach when typing previously-identified genetic polymorphisms in large numbers of samples. One limitation of genotyping arrays with rare variants (e.g., minor allele frequency [MAF] <0.01) is the difficulty that automated clustering algorithms have to accurately detect and assign genotype calls. Combining intensity data from large numbers of samples may...
OBJECTIVE Nocturnal frontal lobe epilepsy (NFLE) can be sporadic or autosomal dominant; some families have nicotinic acetylcholine receptor subunit mutations. We report a novel autosomal recessive phenotype in a single family and identify the causative gene. METHODS Whole exome sequencing data was used to map the family, thereby narrowing exome search space, and then to identify the mutation....
Discriminating the causative disease variant(s) for individuals with inherited or de novo mutations presents one of the main challenges faced by the clinical genetics community today. Computational approaches for variant prioritization include machine learning methods utilizing a large number of features, including molecular information, interaction networks, or phenotypes. Here, we demonstrate...
BACKGROUND Exome or whole-genome deep sequencing of tumor DNA along with paired normal DNA can potentially provide a detailed picture of the somatic mutations that characterize the tumor. However, analysis of such sequence data can be complicated by the presence of normal cells in the tumor specimen, by intratumor heterogeneity, and by the sheer size of the raw data. In particular, determinatio...
OBJECTIVE To identify the causative gene in an autosomal dominant limb-girdle muscular dystrophy (LGMD) with skeletal muscle vacuoles. METHODS Exome sequencing was used to identify candidate mutations in the studied pedigree. Genome-wide linkage was then used to narrow the list of candidates to a single disease-associated mutation. Additional pedigrees with dominant or sporadic myopathy were ...
OBJECTIVE Distal renal tubular acidosis (dRTA) is characterized by metabolic acidosis due to impaired renal acid excretion. The aim of this study was to demonstrate the genetic diagnosis of four children with dRTA through use of whole-exome sequencing. METHODS Two unrelated families were selected; a total of four children with dRTA and their parents, in order to perform whole-exome sequencing...
OBJECTIVE We provide the proof of principle that exome sequencing of only two affected siblings born to first-cousin parents is capable of directly identifying a single candidate gene for an autosomal recessive disorder. This strategy, which we call EX-HOM (EXome HOMozygosity), combines in a single step the capacity of exome sequencing to identify all the coding variants present in a genome wit...
Recent data suggest that T-cell reactivity against tumor-specific neo-antigens may be central to the clinical efficacy of cancer immunotherapy. The development of personalized vaccines designed to boost T-cell reactivity against patient specific neo-antigens has been proposed largely on the basis of these findings. Work from several groups has demonstrated that novel tumor-specific antigens can...
PURPOSE Stargardt disease (STGD) is a common macular dystrophy in juveniles that is commonly inherited as an autosomal recessive trait. Mutations in five genes (ABCA4, PROM1, ELOVL4, BEST1, and PRPH2) have been reported to be associated with STGD. In the present study, we aimed to identify the pathogenic mutations in affected members in a Chinese STGD pedigree. METHODS One patient was selecte...
