Can wpw be passed down to children? my mother-in-law suffers from the condition and i am currently pregnant and concerned for my baby.

Minimal chance: Some familial influence is reported in WPW but the disorder is uncommon & the mode of inheritance is unknown. It probably increases the offspring of a case <5% & less so if one generation later. A visit to a genetic counselor could help you identify specifics for your individual risks with any pregnancy.They are affiliated with children's hospitals & med schools.

Maybe. : There are some inherited forms. Discuss screening with your pcp.
