a splice site 1 predicted to cause a premature stop codon and 13 predicted to cause novel amino acid sub-stitutions The majority of children had a mutation in the linker region often 1399G!A (A467T) and a mutation affecting the polymerase domain Others had mutations throughout the gene and 11 had 3 or more substitutions
Jan 07 2017Interactions between genes and environment are critical factors for causing cancer in humans The genotoxicity of environmental chemicals can be enhanced via the modulation of susceptible genes in host human cells DNA polymerase kappa (Pol κ) is a specialized DNA polymerase that plays an important role in DNA damage tolerance through translesion DNA synthesis
Human cytomegalovirus (HCMV) resistance to antivirals is a major problem in immunocompromised patients Drug resistance is characterized by phenotypic testing or genotypic analysis of the phosphotransferase (UL97) and DNA polymerase (UL54) genes However genotypic assays require further characterization of unknown mutations in the drug resistance phenotype Here we describe a novel

May 01 2008Nucleotide sequencing of the highly conserved SMPD3 gene in a large panel of human cancers revealed mutations in 5 (5%) of 92 acute myeloid leukemias (AMLs) and 8 (6%) of 131 acute lymphoid leukemias (ALLs) but not in other tumor types In a subset of these mutations functional analysis indicated defects in protein stability and localization
Dec 01 1999Of the 12 novel α-Gal A coding-region point mutations all but one (P259L) were detected in classically affected probands including 10 missense and 2 nonsense mutations The missense mutations included the following: (1) a T-to-C transition of genomic nt g7323 in codon 142 resulting in a replacement of cysteine with arginine (C142R) (2) a G-to-A transition of genomic nt
Identification of a novel mutation in the polymerase delta 1 (POLD1) gene in a lipodystrophic patient affected by mandibular hypoplasia deafness progeroid features (MDPL) syndrome Metabolism 2014 63(11):1385-9 (ISSN: 1532-8600)
Mutations of p53 tumor suppressor gene are the most common genetic alterations in a variety of human carcinomas The sites of p53 mutations however vary in different cancers The present study was designed to characterize p53 mutations in 40 primary human renal cancer specimens
Gene therapy has been proposed as a definitive cure for β-thalassemia We applied a gene targeting approach based on the introduction of small DNA fragments (SDF) into erythroid progenitor cells to specifically modify the β-globin gene sequence at codon 39 The strategy was first tested in normal individuals by delivering mutant SDF that were able to produce the β39 (C→T) mutation
Patients 1 2 and 3 all had severe FV deficiency and undetectable levels of FV DNA sequence analysis of the FV gene revealed 2 novel frameshift mutations and a novel nonsense mutation associated with an FV null allele Patients 2 and 3 were both homozygous for a mutation in exon 13 respectively a 1-bp deletion between nts 4291 and 4294 and
Somatic mutation: the size of the patch will depend on the timing of the mutation during what type of mutation does the statement the earlier the mutation the larger the patch fit somatic mutation an individual who has somatic regions that are genotypical different from each other is called
Disclosed is a DNA polymerase from Thermoanaerobacter tengcongenesis This enzyme is useful for procedures requiring strand-displacing DNA synthesis such as SDA and for reverse transcription Included within the scope of the present invention are various mutants (deletion and substitution) that retain the ability to replicate DNA with substantially the same efficiency as the native

Feb 19 2003A subgroup of patients with severe combined immunodeficiency (SCID) and increased cellular radiation sensitivity (RS-SCID) have mutations of Artemis a gene that encodes a protein essential for V(D)J recombination and DNA double-strand break repair RS-SCID described to date are either of European origin or are Athabascan-speaking native Americans belonging to the Navajo and
Mar 19 2003Epidermolysis bullosa simplex is a group of blistering skin disorders caused by defects in one of the keratin genes KRT5 and KRT14 Previously reported KRT5 and KRT14 mutations are clustered in several hotspots namely the rod ends of the 1A and 2B domains and in the non‐helical linker region L12 Therefore genomic KRT5 and KRT14 mutation analysis was initially limited to these
Jul 18 2005DNA polymerase γ is responsible for replication and repair of the mitochondrial genome Human DNA polymerase γ is composed of a 140-kDa catalytic subunit and a 55-kDa accessory subunit Mutations in the gene for the catalytic subunit (POLG) have been shown to be a frequent cause of mitochondrial disorders
A novel RLBP1 truncating mutation was detected in a young affected by RPA Although her parents are not consanguineous the mutation was observed in a homozygous condition Being them native of the same small Sicilian town of Fiumedinisi the hypothesis of a geographical area-related mutation was assessed and confirmed
Apr 20 2016However a high-throughput screening approach would allow analysis of large numbers of mutations and identification of currently unknown human adaptation mutations Using a comprehensive database approach in this study enabled us to identify a number of novel putative human adaptation mutations in the polymerase complex of H5N1 clade 2 2 1 viruses
