My daughter has had a 20 week scan and her baby has a hand missing but they also mentioned his legs were at the shorter end of the scale. She is waiting to have an amneo test.   They mentioned his legs being a little shorter even though they said they looked normal could this be a sign there is more wrong than just his hand missing.  She had a miscarriage before getting pregnant this time.
There are chances of this baby having other congenital anomalies also. There could be generalized shortening of all the limbs. She needs to be further investigated
