These recommendations mirror guidelines for other neurodevelopmental disorders such as intellectual disabilities and developmental delays in that they recommend genome and exome sequencing as first-tier tests. A child with neurodevelopmental disorders is likely to wait2 more than six years on average for a genetic diagnosis; accrue more than $10,000 in additional health costs; and undergo more than five uninformative tests. These new guidelines demonstrate the importance and advantage of ordering exome sequencing first rather than chromosomal microarray analysis panel testing; in which diagnostic rates are highest3 for whole genome sequencing (48%), followed by whole exome sequencing (24%). Chromosomal microarray analysis has the lowest diagnostic rate (9%).
Leveraging one of the world’s largest data sets of more than 400,000 clinical exomes, we have seen first-hand the power of genomic sequencing for improving diagnostic certainty and believe these new guidelines will unlock insights and improve patient care.
