Preferences for results from genomic microarrays: comparing parents and health care providers.


Chromosomal microarray (CMA) testing is now performed frequently in paediatric care. Although CMAs improve diagnostic yields, they increase detection of variants of unknown and uncertain clinical significance (VUS). Understanding parents', paediatricians' and genetic health professionals' (GHPs) views regarding variant disclosure may reduce the potential for communication of unwanted information. A questionnaire was designed to compare disclosure preferences of these three groups in Australia. One hundred and forty-seven parents, 159 paediatricians and 69 GHPs hold similar views with at least 89% of respondents certainly or probably favouring disclosure of all categories of variants. However, some differences were observed between health care providers (HCPs: paediatricians and GHPs) and parents, who were less sure of their disclosure preferences. There was consensus among respondent groups that knowledge of a variant of certain clinical significance would provide more practical and emotional utility compared to VUS. Compared to HCPs, parents placed more emphasis on using knowledge of a VUS when considering future pregnancies (p < 0.001). This study may help HCPs anticipate parents' preferences for genomic testing. As whole exome/genome sequencing is integrated into clinical practice, the potential for differing views of parents and HCPs should be considered when developing guidelines for result disclosure.
