Information and genetic counselling for psychiatric risks in children with rare genomic disorders

Abstract

AbstractPurposeGenomic medicine has transformed the diagnosis of neurodevelopmental disorders. Evidence of increased psychiatric comorbidity associated with genomic copy number and single nucleotide variants (CNV and SNV) may not be fully considered when providing genetic counselling. We explored parents’ experiences of genetics services and how they obtained information concerning psychiatric manifestations.MethodsParents of children diagnosed with genomic variants completed an online survey exploring, (i) how they experienced the genetic diagnosis, and (ii) how they acquired information about psychiatric, developmental and physical manifestations.ResultsTwo-hundred and 86 respondents completed the survey. Thirty percent were unsatisfied with receiving genetic diagnoses. Satisfaction was predicted if communication was by geneticists (p = 0.004); provided face-to-face (p = 0.003); clearly explained (p < 0.001); and accompanied by support (p = 0.017). Parents obtained psychiatric information from non-professional sources more often than developmental (ϕ 0.26, p < 0.001) and physical manifestations (ϕ 0.21, p = 0.003), which mostly came from health professionals. Information from support organisations was more helpful than from geneticists (odds ratio [OR] 21.0, 95% CI 5.1 – 86.8, p < 0.001); paediatricians (OR 11.0, 1.4 – 85.2, p = 0.004); and internet sites (OR 15.5, 3.7 – 64.8, p < 0.001).ConclusionA paucity of professional information about psychiatric risks after genetic diagnosis may impede early diagnosis and intervention for children with high genotypic risks. Planned integration of genomic testing into mainstream services should include genetic counselling training to address the full spectrum of developmental, physical and psychiatric manifestations and timely provision of high-quality information.
