Clinical Info

Abnormal fetal ultrasound findings Ambiguous chromosome results Suspected deletion/duplication syndrome Family history of known or suspected
chromosome imbalances Abnormal maternal serum screening Advanced maternal age
The prenatal targeted CMA focuses on detection of CNVs in approximately 150 cytogenetically relevant regions, including common or novel microdeletion 
and microduplication syndromes. Deletions >1 Mb and duplications >2 Mb in the remainder of the genome are also assessed. In addition, SNP probes 
covering only chromosomes known to contain imprinted regions (specifically, chromosomes 6, 7, 11, 14, 15, and 20) can provide information regarding ROH and UPD on those chromosomes.
