摘要: Abstract Hemophilia A, an X-linked disease caused by deficiency of factor VIII, is characterized variation in clinical severity and coagulation activity. This thought to reflect heterogeneity mutations the VIII gene. Here we describe a CG-to-CA mutation within potential cryptic donor splice site intron 4 gene from patient with mild disease. makes sequence resemble more closely consensus for sites. We infer that activates site, which turn causes defect RNA processing.
