Reported incidence rates of skeletal muscle damage among female carriers (including those who are asymptomatic) range from 2.5 % to 19 %, while the prevalence of dilated cardiomyopathy is 7.3 %–16.7 % in carriers of DMD-causing variants and 0 %–13.3 % in carriers of BMD-causing variants [4]. This evidence concerns the gene DMD and dilated cardiomyopathy.
