Researchers consider MAS to be a rare disease, meaning it affects 1 in every 100,000 to 1 million live births worldwide.1
Because the genetic change or mutation that causes MAS occurs at random very early in fetal development, MAS is not an inherited disease, meaning parents do not pass it on to their children.1
MAS likely occurs equally in males and females.
