Genetic counseling for consumer‐driven whole exome and whole genome sequencing: A commentary on early experiences

Abstract

Counseling after consumer‐driven whole exome sequencing (WES) and whole genome sequencing (WGS) presents challenges for genetic counselors as availability of this testing increases. There are no standard practice guidelines and limited resources for genetic counselors in this area, but consumer demand for counseling and data interpretation exists and is likely to grow along with testing opportunities. In this paper, we comment upon our experiences as three independent, private practice genetic counselors who have provided counseling services for clients with WES/WGS reports and data. In our counseling experience, we have encountered three main types of client motivation for seeking testing and counseling: generally healthy individuals who are curious to learn more about their genomic data, individuals with family histories of various conditions, and/or who want to better understand specific disease risks, and individuals who are ill, undiagnosed and searching for an understanding of their ailments. Research is needed to better understand client motivations for undergoing testing and counseling, as well outcomes of counseling sessions. In addition to improvements in variant identification, classification and bioinformatics, there is a need for practice guidelines, counseling resources, service delivery models, and efforts to increase awareness and access to genetic counseling services.
