There is something to that, at least in my case. My mom was a smoker, even though she only smoked until the 2nd trimester (i think). Anyways I have prostrated(sp?) toes. The middle ones are permanently curled up, although fully functional.
My husband has the same condition. His mother (a Pentecostal preacher) NEVER smoked.
My mom smoked cigars, and I post on FR.
In my experience the one child I know who was born with finger abnormalities was the child of 2 non-smokers so can I take it that not smoking may cause defects?
I have an old boyfriend who had webbed toes. I wonder if his mom smoked.
