This invention discloses a primer set, kit, and application for
prenatal screening of RhD, belonging to the field of
gene detection technology. Based on
genetic data of the
Chinese population, this invention proposes four specific primer pairs. Through specific amplification, it can effectively distinguish four genes: RhD complete deletion
gene, RhD-CE(2-9)-D
hybrid gene, RhD1227A, and RhD wild-type gene. Compared with existing technologies, by incorporating RhD
exon9 amplification, it can detect the RhD1227A gene, which accounts for approximately 16.3% to 32.6% of RhD-negative blood types in the
Chinese population, reducing the probability of false positives due to paternal RhD1227A gene
carriage. This provides a more accurate, low-cost, rapid, and convenient option for
prenatal screening of RhD in the
Chinese population.
