Based on current published guidelines, exome or genome sequencing can now be considered as first-tier tests for patients with unexplained epilepsy, developmental delay, intellectual disabilities and/or congenital anomalies.

The XomeDxXpress® test is whole exome sequencing with an expedited turnaround time (TAT) of approximately 2 weeks. A verbal result is given within 7 calendar days after the start of testing and will include pathogenic and/or expected pathogenic variants in known disease-causing genes (Human Genome Mutation Database genes). A written report including all clinically relevant, confirmed variants will be reported within approximately 2 weeks after the start of testing. Because of the rapid TAT, samples on the proband and both biological parents, when included, must be submitted at the same time, along with clinical information, in order to begin testing. Please email [email protected] to discuss prior to sending in samples.
