The term<unk>  is Greek for "death bearing". Children with this condition are usually stillborn or die shortly after birth from respiratory failure. A small number have survived into childhood, and a very few beyond. Survivors have difficulty breathing on their own and require respiratory support such as high flow oxygen through a canula or ventilator support via tracheostomy. There may also be evidence of spinal stenosis and seizures. The oldest known living<unk>  survivor as of 2013 was a 29-year-old woman. One man lived to be 26 years old. Another man lived to age 20. It was reported in 1998 that a 21 year old man with the condition lives in the United States, while two children with<unk>  aged 10 and 12, a boy and a girl, were known in Germany. There was also a 6-year-old boy living with<unk>  and two 1-year old boys. As of 2021 Christopher Álvarez, 24, is a Colombian living with<unk>  in New York City.
