Intron 1 and 22 inversions were looked for in 80 severe haemophilia A patients in India using PCR and multiplex Long-Distance Subcycling-PCR, respectively. Intron 1 inversion was seen in 3 (3.75%) and intron 22 inversion was seen in 35 (43.75%) patients. Of severe haemophilics, 47.5% had either of these inversions. It is thus suggested that screening for inversions may be the first step in genetic testing of Indian haemophilics.
