Allelic Frequencies of HPA-1 to 5 Human Platelet Antigens in Patients Infected With Hepatitis C Virus
(Wiley-liss, 2009-04-01)
Studies have suggested that hepatitis C virus (HCV) may infect not only hepatocytes but may also be carried by platelets. Platelets express more than 20 polymorphic antigenic determinants on their surface, which are called ...
Distinction between plant samples according to allele dosage by semiquantitative polymerase chain reaction
(Genetics and Molecular Research, 2017)
Variation of genetic expression during development, revealed by esterase patterns in Aedes aegypti (Diptera, Culicidae)
(2004-04-01)
Polyacrylamide gel electrophoresis was used to analyze esterase patterns during development of Aedes aegypti from the cities of Marília and São José do Rio Preto (SJRP), Brazil. The zymograms showed a total of 23 esterase ...
Hemoglobin and HFE gene polymorphisms in Brazilian populations in regions endemic for malaria
(Funpec-editora, 2006-01-01)
Our objective was to determine how the distribution of red blood cell diseases is related to malaria occurrence in north Brazil, a region endemic for malaria. We evaluated the incidence of two mutations in the HFE gene, ...
A nonsynonymous mutation at HLA-E defines the new E*01:06 allele in Brazilian individuals
(Wiley-Blackwell, 2014)
Allelic polymorphisms of human Fc gamma receptor IIa and Fc gamma receptor IIIb among distinct groups in Brazil
(Amer Assoc Blood Banks, 2000-11-01)
BACKGROUND: the Fc gamma RIIA gene is expressed in two polymorphic farms, R131 and H131, which differ by the replacement of histidine by arginine at position 131. the FCGR3B (Fc gamma RIIIB) gene exists in two allelic ...
Novel Complex ABCA4 Alleles in Brazilian Patients With Stargardt Disease: Genotype-Phenotype Correlation
(Assoc Research Vision Ophthalmology Inc, 2017)
PURPOSE. To analyze the presence of complex alleles of the ABCA4 gene in Brazilian patients with Stargardt disease and to assess the correlation with clinical features. METHODS. This was an observational cross-sectional ...
Genetic relatedness of Plasmodium falciparum isolates and the origin of allelic diversity at the merozoite surface protein-1 (MSP-1) locus in Brazil and Vietnam
(2003-07-23)
Background: Despite the extensive polymorphism at the merozoite surface protein-1 (MSP-1) locus of Plasmodium falciparum, that encodes a major repetitive malaria vaccine candidate antigen, identical and nearly identical ...
Tapping natural variation at functional level reveals allele specific molecular characteristics of potato invertase Pain‐1
(Plant, Cell and Environment, 2018)
Clinical and molecular study of a new form of hereditary myotonia in Murrah water buffalo
(2013-03-01)
Hereditary myotonia caused by mutations in CLCN1 has been previously described in humans, goats, dogs, mice and horses. The goal of this study was to characterize the clinical, morphological and genetic features of hereditary ...
