Project description:<p>The ultimate purpose of this research is to identify genes causing hereditary disorders. We are scaling a new approach to identify the candidate genes and gene mutations that underlie rare human Mendelian (a set of primary tenets relating to the transmission of hereditary characteristics from parent to child) diseases by using exome (protein coding segments of DNA) resequencing.</p> <p>The exome sequences of ten unrelated individuals with a diagnosis of Kabuki Syndrome (OMIM: <a href="http://www.ncbi.nlm.nih.gov/omim/147920" target="_blank">147920</a>) were obtained by massively parallel DNA sequencing.</p>

Project description:<p>The NHGRI Next Generation Mendelian Genetics project uses exome resequencing to identify variants in unsolved Mendelian diseases.</p> <p>Ehlers-Danlos syndrome Type VIII is a dominantly inherited connective tissue disorder that is distinguished from other forms of EDS by significant early-onset periodontal disease. Although the clinical phenotype is well delineated, the underlying molecular basis remains unknown. By studying a large family of affected and unaffected individuals with the EDS VIII by exome sequencing, we hope to identify unique regions of homology to assist in identifying the causative gene. </p>
Project description:<p>The NHGRI Next Generation Mendelian Genetics project uses exome resequencing to identify variants in unsolved Mendelian diseases.</p> <p>Samples were collected from a single, multi-generational family with the same phenotype of exaggerated muscular development (muscular hypertrophy) and strength characterized by reduced fat pad thickness under the skin. All family members deny "body building" activities, and are so far negative for known gene mutation that have been identified as associated with excessive muscle development. All family members have examples of demonstrating extraordinary strength occurring both in childhood and old age. No negative associated phenotype traits with the muscle hypertrophy phenotype have been identified.</p>
Project description:<p>The NHGRI Next Generation Mendelian Genetics project uses exome resequencing to identify variants in unsolved Mendelian diseases.</p> <p>The research study procedures included the collection of a fasting blood sample, 2 medical history/life style questionnaires and a measurement of subjects' waist circumference that were completed many years ago. Blood samples were analyzed for metabolic markers including cholesterol, HDL, triglycerides and APOE. Genetic tests targeted known and novel genes and polymorphisms associated with carotid artery disease. </p>

Autosomal recessive mutations in PFP1, UNC13D, STX11, STBP2, or RAB27, and hemizygous mutations in SH2D1A or BIRC4, account for known causes of the disease, but 30-70% of patients in North America lack a known genetic etiology. This project was designed to identify additional genetic abnormalities from HLH patients. </p> <p>The exome sequences of four unrelated individuals with a diagnosis of HLH, but without mutations in genes known to cause disease, were obtained by massively parallel DNA sequencing.</p>
