These infants are already born with sirenomelia.Sirenomelia is an extremely rare congenital developmental disorder characterized by the anomalies of the lower spine and the lower limbs.It is where infants are mostly affected.Sirenomelia is a rare and lethal congenital anomaly.
So what are the causes of sirenomelia?
Actually the exact cause of sirenomelia is unknown.But based on my research, there are two reported cases of infants having a sirenomelia and the causes were drug abuse and diabetes.The first case was a history of tobacco use.She was otherwise healthy with no known history of genetic or congenital anomaly in her family.The second case had a postpartum investigation revealed the presence of diabetes mellitus.There was no history of drug intake and radiation exposure.There is no treatment available for sirenomelia, howe in ver prevention is possible and should be the goal.
