>In hindsight a DNA test might have revealed achondroplasia

It might have, but remember my diagnosis were conducted in 1994,2001 (though best hospital in India of that time) to conclude I was a normal kid with some vitamin deficiencies.

Even now, I doubt whether even now pregnancy scans test for achondroplasia. I was informed recently that it was mentioned by a doctor in Singapore that, achondroplasia tests should be requested during pregnancy tests.

I'm not sure whether it is part of pregnancy scans in Western countries & how common is the DNA tests for achdonroplasia.
