Background:Thalassemia is a prevalent condition characterized by decreased production or absence of hemoglobin globin *** are 2 types of thalassemia,alpha thalassemia and beta thalassemia(β-thalassemia),classified according to defects in the alpha or beta protein chain.β-Thalassemia results from a diverse range of mutations in theβsubunit of the hemoglobin gene(HBB).This results in severe reductions in erythrocyte and hemoglobin ***,more than 40,000 babies are born withβ-thalassemia *** are approximately 80 millionβ-thalassemia *** Pakistan,the annual birth rate ofβ-thalassemia major carriers is approximately 6,000,and 50,000 to 100,000 patients suffer from this common inherited ***-1,IVSI-5(G>C),Fr 8/9(+G),Fr 41/42(-TTCT),and del 619 are the 5 most common mutations that account for 90%ofβ-thalassemia cases in *** study aimed to investigate the prevalence ofβ-thalassemia mutations(IVSI-5,Fr 41/42,and Fr 8/9)in the Swat district and to analyze the blood morphology of different mutant thalassemia blood ***:A cross-sectional study was performed at the Forensic Research Lab University of Swat from December 2021 to March *** study included a total of 150 blood *** analysis of blood morphology through microscopy was carried out on samples from patients with differentβ-thalassemia mutations and normal *** DNA extraction was performed according to the Sambrook protocol,and DNA was quantified via agarose gel *** mutations were detected by amplification refractory mutation system(ARMS)-polymerase chain reaction(PCR).The frequencies of differentβ-thalassemia mutations were ***:Thalassemia blood cells were more hypochromic and microcytic than normal blood cells,although no differences were detected in the morphology of IVSI-5,Fr 8/9,or CD41/42 mutant blood *** IVSI-5,Fr 8/9,and CD41/42 mutations were analyzed through agarose ge
