Abstract:
OBJECTIVE:To perform dried blood spots thalassemia gene detection in patients with positive blood phenotypes by microarray technology, and evaluate its value in clinical detection.
METHODS:DNA samples were extracted from dried blood spots of 410 patients. Microarray technology was used to detect 3 deletion and 3 non-deletion types of α-thalassemia and 19 β-thalassemia point mutations which were common gene mutions in China.
RESULTS:There were 357 positive cases in all the 410 tested samples with the positive rate 87.07%, among which 299 cases (72.93%) carried deletion or point mutations of α-thalassemia, 29 cases (7.07%) carried point mutations of β-thalassemia and 29 cases (7.07%) carried gene mutations of complex αβ-thalassemia syndrome. The mutations of α-thalassemia were involved with --
CONCLUSION:The most common genetic mutations are --
