What is 1q43q44 deletion syndrome?
Background. Microdeletion of 1q43q44 causes a syndrome characterized by intellectual disability (ID), speech delay, seizures, microcephaly (MIC), corpus callosum abnormalities (CCA) and characteristic facial features. Duplication of 4q is presented with minor to severe ID, MIC and facial dysmorphism.
What is the long term outlook for a child with DiGeorge syndrome?

What happens if you have 16p11 deletion?
Most people tested for the 16p11.2 deletion have come to medical attention as a result of developmental delay or autistic behaviors. Other individuals with the 16p11.2 deletion have no associated health or behavioral problems, and so the deletion may never be detected.
What is the 16p11 CNV variant?
The 16p11.2 BP4 and BP5 region, is a recurrent ∼600kb copy number variant (CNV), and deletions are one of the most frequent etiologies of neurodevelopmental disorders and autism spectrum disorder with an incidence of approximately 1/2000. Deletion carriers have delays in early neurodevelopment that …
What is the phenotype of recurrent microdeletion?
