A new mutation in the gene encoding mitochondrial seryl-tRNA synthetase as a cause of HUPRA syndrome
BACKGROUND HUPRA syndrome is a rare mitochondrial disease characterized by hyperuricemia, pulmonary hypertension, renal failure in infancy and alkalosis. This syndrome was previously described in three patients with a homozygous mutation c.1169A > G (p.D390G) in SARS2, encoding the mitochondrial seryl-tRNA synthetase. CASE PRESENTATION Here we report the clinical and genetic findings in a gir...
In disequilibrium mapping from data on a rare allele, interest may focus on the ancestry of a random sample of current descendants of a mutation. The mutation is assumed to have been introduced into the population as a single copy a known time ago and to have reached a given copy number within the population. Theory has been developed to describe the ancestral distribution under arbitrary patte...
BACKGROUND Somatic mutations in the tyrosine kinase domain of the epidermal growth factor receptor (EGFR) are involved in tumorigenesis and response to targeted therapies in distinct cancer types. Squamous cell carcinomas of the head and neck (HNSCC) show an incidence of EGFR mutations varying from 7% in Asians to 0% to 4% in white patients. Mutational screening predominantly focuses on the ana...
Human Alpha 1 antitrypsin (AAT) or protease inhibitor (PI) is a highly polymorphic glycoprotein. In this review report distributions of all detected AAT allelic variants in different world populations are collected showing their anthropological usefulness. Some variants are related to AAT deficiency (AATD) which is one of the most common genetic disorders worldwide. Data on PIS and PIZ, most co...
BACKGROUND A recent study of familial and early onset prostate cancer reported a recurrent rare germline mutation of HOXB13 among men of European descent. The gene resides within the 17q21 hereditary prostate cancer linkage interval. METHODS We evaluated the G84E germline mutation (rs138213197) of HOXB13 in a case-control study of familial prostate cancer at Vanderbilt University (Nashville, ...
Rare stochastic mutations may accumulate during dormancy of stem-like cells, but technical limitations in DNA sequencing have limited exploring this possibility. In this study, we employed a recently established deep-sequencing method termed Duplex Sequencing to conduct a genome-wide analysis of mitochondrial (mt) DNA mutations in a human breast stem cell model that recapitulates the sequential...
rare bleeding disorders (rbds) are a heterogeneous group of disorders including different types of coagulation factor deficiencies. the disorders are inherited in an autosomal recessive manner with different frequencies varying from 1:500000 to 1:2000000. patients affected with rbds are presented with a wide spectrum of clinical manifestations ranging from mild to life threatening bleeding diat...
crouzon syndrome is a rare autosomal dominant premature cranyosynostosis, caused by fibroblast growth factor receptor 2 gene mutation on chromosome 10. the predominant skull and facial malformations with potential compromise airway make the crouzon syndrome a demanding issue for anesthesiologists and surgeons, required dynamic team work. in this report we describe a child, a known case of crouz...
schimke immuno-osseous dysplasia is a rare autosomal recessive multisystem disorder characterized by steroid-resistant nephrotic syndrome, immunodeficiency, and spondyloepiphy-seal dysplasia. mutations in swi/snf2 related, matrix associated, actin dependent regulator of chromatin, subfamily a-like 1 (smarcal1) gene are responsible for the disease. the present report describes, for the first tim...
The combination therapy of lumacaftor and ivacaftor (Orkambi®) is approved for patients bearing the major cystic fibrosis (CF) mutation: ΔF508 It has been predicted that Orkambi® could treat patients with rarer mutations of similar "theratype"; however, a standardized approach confirming efficacy in these cohorts has not been reported. Here, we demonstrate that patients bearing the rare mutatio...
