Clinical Significance

Determine genetic cause of developmental delay (DD) or mental retardation (MR) in patients with or without dysmorphic features.

Confirm, exclude, (or clarify) the diagnosis of known chromosomal syndromes.

Assist in clinical management and genetic counseling.

High resolution detection of chromosome segments involved in deletions, duplications, and long continuous stretches of homozygosity.
