Basically the results are inconclusive but given my sons birth defects there is a Good chance it IS genetic which means overall there's a 1% (if it was sporadic) - 25% (genetic) chance of recurrence. There are a few different types of syndromes that cause the absence of limbs - the worst is 'x-linked' something - and that would give us a 50% chance of recurrence in a boy but pose minimal risk for a girl. The other is 25% in either gender. I'm kind of thinking it IS that x-linked one since we have a perfectly normal healthy daughter and it was our son that was affected.
We're both feeling pretty messed up right now but we're not going to let it stop us from trying again. Next time I get pregnant I will be referred to a specialist for an early scan to be sure everything is developing properly and then sent to a High Risk fetal medicine clinic in Edmonton for a scan at 18 weeks. I have the feeling I will never have a son on Earth

don't get me wrong - I just want another baby, a sibling for Mattea, I don't really care if it's a boy or a girl but just knowing there's a chance I will NEVER have a boy... ugh
