The prevalence of factor XIII deficiency is about 1 case per 2 million in the general population. Worldwide, the prevalence is highest in the Sistan and Baluchistan province of Iran. [7] In addition to Iran, population-specific mutations due to founder effects have been reported in Pakistan, India, Tunisia, and Finland.

A study by Gebhart et al of Austrian patients with mild to moderate bleeding disorders found that out of 418 individuals with these conditions, just one (0.2%) had factor XIII deficiency. Factor VIII, IX, and XI deficiencies occurred in 11 (2.6%), 3 (0.7%), and 3 (0.7%) patients, respectively. [8]
