Background and clinical significance

Microarray analysis is  performed on cultured fibroblasts only if peripheral blood is unavailable, or if mosaicism is suspected.

Approximately 10-20% of individuals with unexplained developmental delay or multiple congenital anomalies will have a CNV considered to be clinically relevant.

Disease condition

Developmental delay and or congenital anomalies
