Diagnostic distal 16p11.2 deletion in a preterm infant with facial dysmorphism

ABSTRACT

The 16p11.2 microdeletion has been reported in patients with developmental delays and intellectual disability. The distal 220-kb deletion in 16p11.2 is associated with developmental delay, autism spectrum disorder, epilepsy, and obesity at a young age. We have reported a case of distal 16p11.2 deletion syndrome in a preterm infant with unusual facial morphology and congenital heart disease. We suggest using chromosome microarray analysis to detect chromosomal abnormalities in newborns, especially preterm infants with unusual morphologies.
