UNC Geneticist Comments on Testing Laboratories’ Duty to Return Genomic Data to Patients

UNC’s Karen Weck responds to my previous GLR post:

I agree in principle that patients have the right to access their genomic data; however, in practice it is much more complicated (as things often are). Giving a patient his/her raw sequencing data would be meaningless – it is the interpretation of the clinical significance of sequence data that is important when reporting results. This latter requires the expertise of molecular genetic laboratorians and clinical geneticists. We do not return all genomic sequence variants to individuals in exome sequencing, for example when we determine that they are unlikely to be contributory to their disease or medical health. It is important to those of us doing this that we retain the ability to use our professional judgement to determine what should be reported to patients as medically relevant, primarily so as not to dilute important medical information with irrelevant information.
