1. High prevalence of serological weak D phenotype and preponderance of weak D type 4.0.1. genetic variant in a Nigerian population: implications for transfusion practice in a resource-limited setting
ABSTRACT Introduction: Prevalence of RhD negative phenotype in Nigeria is low; this leads to scarcity of RhD negative red cells for transfusion. Serological and molecular genotyping of RhD negative individuals for weak D types could reduce this scarcity. The aim of this study was to determine the serological prevalence and molecular types of weak D phenotyp

2. Polimorfismo do gene RHD em indivíduos com fenótipo RhD (RH1) negativo e portadores de aloanticorpo anti-D. / RHD GENE POLYMORPHISMS IN ALLOIMMUNIZED RhD NEGATIVE INDIVIDUALS
O fenótipo RhD negativo é decorrente da deleção total do gene RHD na quase totalidade dos caucasianos, por volta de 20% dos africanos e em 70% dos asiáticos. Em africanos, o RHDΨ caracterizado por uma inserção de 37 pb no exon 4 é um dos principais responsáveis pelo fenótipo RhD negativo. Em asiáticos, o DEL é uma importante causa de RhD neg

3. Diagnosis of the RhD status using conventional polymerase chain reaction / Diagnóstico do fator RhD utilizando a reação em cadeia da polimerase convencional
Molecular biology techniques have added some advantages to conventional diagnosis of the Rhesus (Rh) blood group. Many researches have demonstrated the practical superiority of RhD genotyping using polymerase chain reaction (PCR) over phenotypic identification tests obtained by hemagglutination. The use of different kinds of molecular analysis techniques and

4. Presence of the RHD pseudogene and the hybrid RHD-CE-Ds gene in Brazilians with the D-negative phenotype
The molecular basis for RHD pseudogene or RHDpsi is a 37-bp insertion in exon 4 of RHD. This insertion, found in two-thirds of D-negative Africans, appears to introduce a stop codon at position 210. The hybrid RHD-CE-Ds, where the 3' end of exon 3 and exons 4 to 8 are derived from RHCE, is associated with the VS+V- phenotype, and leads to a D-negative phenot

5. The RHD gene is highly detectable in RhD-negative Japanese donors.
Recent molecular studies on the Rh blood group system have shown that the Rh locus of each haploid RhD-positive chromosome is composed of two structural genes: RHD and RHCE, whereas the locus is made of a single gene (RHCE) on each haploid RhD-negative chromosome. We analyzed the presence or absence of the RHD gene in 130 Japanese RhD-negative donors using t
