De novo mutations and environmental modifiers: lessons from neural tube defects.

Abstract excerpt

Spina bifida is a clinically and etiologically heterogeneous group of neural tube defects (NTDs) that includes meningomyelocele. While folic acid (FA) supplementation has reduced the incidence by 30-50%, genetic contributors remain only partially understood. New trio sequencing technology has identified de novo mutations (DNMs) in 20-25% of patients. Two recent large-scale genomic studies identified DNMs in 187...
