Usually X-linked recessive inheritance is seen with this syndrome.
Autosomal dominant and recessive as well as X-linked recessive inheritance has been described.
Because we successfully used maternal serum to diagnose fetal gender, our diagnostic method may be useful in place of invasive prenatal diagnostic methods such as amniocentesis and chorionic villi sampling in cases of X-linked recessive inheritance. If a fetus has a risk of X-linked recessive inheritance and is found to be female by our maternal serum-based method, use of an invasive prenatal diagnostic method may not be necessary.
