Hello, I am 5 weeks pregnant with my first baby. I'm 34, 5"2 12 stone. My partners son from a previous relationship has Polands Syndrome. Firstly I would like to know if it is genetic (both monther and father do not have Polands Syndrome and no history of it) and also something the baby can be tested for while i'm pregnant? Thank you

Summarized question: Is Poland syndrome genetic in nature?
