Wrongful Life Lawsuits

They aren't new news, but in light of the recent higher level of awareness over the abortion issue, this seems like an appropriate time to bring it up again.

Around 7 years ago the issue shocked me. I'd never heard of a wrongful life lawsuit until then. Apparently, some people had taken to suing doctors who refused to perform an abortion or parents who chose to not abort when they knew the child had a birth defect that would make their quality of life more expensive, painful, and/or difficult.
Some parents were suing doctors for wrongful life, doctors who failed to tell them a child would be born with a birth defect or that they feel failed to perform adequate testing or tested too late, so that the parent couldn't abort the baby at that point in time.

Does anyone know what's going on in this area of the battlefield between life and death? Have case-laws been established? Curious as to how this is playing out. It's a little-known and little-discussed aspect with major possibilities for the use of instilling fear into parents expected a child with a birth defect and wow...how horrible and devastating must that be for people with birth defects...to hear that some people consider them "wrongful lives?"
