This can happen for a few reasons. Some variants have been noted, but not yet published in a peer-reviewed journal. Alternatively, some variants have been published, but have not been validated in-house or by other researchers. At Embark, we believe that scientific peer review and replicability are critical requirements and do not offer variant-based tests that lack either. We review the literature regularly to assess new publications. In general, each year, we update our testing platform to include tests for variants that have recently been published or validated. These tests will be visible on our website when available.
Embark also has a strict quality control process, and we validate each test against samples from known carrier and at-risk (hetero- and homozygous) dogs. If there is a published variant test for your breed that is currently not offered by Embark, please contact us.
