Researchers at UC San Diego link a common chromosomal microdeletion to spina bifida and suggest folic acid supplements may reduce risk.

Researchers at UC San Diego discovered a link between a common chromosomal microdeletion and spina bifida, the most prevalent nervous system disorder. The deletion, present in 1/2500 live births, raises spina bifida risk 10x. Their study also suggests folic acid supplements may reduce risk and severity. The findings, published in Science, could improve outcomes for children with the condition.
