What percent of the population has fragile x syndrome? The fragile X syndrome affects about 1 in 4,000 males and 1 in 6,000 to 8,000 females in the USA; that is, it affects about twice as many males as it does females. However, about four times as many females appear to be carriers of the altered gene as do males (1:250 females and 1:1000 males).
How common is fragile X syndrome in the world? Fragile X syndrome has been extensively studied around the world, especially in Western countries. The general prevalence with a full mutation is estimated at 1/4,000 males and 1/5000–1/8,000 females (9). Since FXS is a typical sex-linked disorder, female prevalence is approximately one-half of the male rate.
What are the chances of having a child with fragile X syndrome? People with a full mutation (more than 200 repeats) have FXS. With each pregnancy, women have a 50% chance of passing fragile X on to their child (sons or daughters).
Is fragile X syndrome more common in females? FXS affects both males and females. Females often have milder symptoms than males. The exact number of people who have FXS is unknown, but a review of research studies estimated that about 1 in 7,000 males and about 1 in 11,000 females have been diagnosed with FXS.
