As a first-tier, postnatal test per the American College of Medical Genetics (ACMG)’s practice guidelines for individuals with multiple anomalies not specific to well-delineated genetic syndromes, individuals with apparently nonsyndromic developmental delay or intellectual disability and individuals with autism spectrum disorders.
As an appropriate follow-up for individuals with unexplained developmental delay/intellectual disability, autism spectrum disorders, or multiple congenital anomalies with a previously normal conventional chromosome study due to the superior resolution of the chromosomal microarray testing.
Determining the size, precise breakpoints, and gene content, and unveiling unappreciated complexity of abnormalities detected by other methods such as conventional chromosome and FISH studies.
Determining if apparently balanced abnormalities identified by previous conventional chromosome studies have cryptic as a large proportion of such rearrangements appear balanced at the resolution of a chromosome study, but may actually be unbalanced when analyzed by higher-resolution chromosomal microarray.
