Description

AIM: To investigate paediatricians' expectations and perspectives of genetic testing for children with developmental disorders. METHODS: Paediatricians working in a developmental clinic were surveyed each time they ordered a chromosomal microarray (CMA) for a child with developmental disorders. Clinical charts were reviewed. Results were analysed using mixed methodology. RESULTS: Ninety-seven % (73/76) of surveys were completed. Paediatricians reported that 36% of parents had difficulties understanding genetic testing and that 40% seemed anxious. The majority expected testing to have positive impacts on children/families. The themes raised were (i) clarifying the diagnosis (56%), (ii) understanding the aetiology of the condition (55%), (iii) enabling prenatal diagnosis/counselling (43%), (iv) improving medical care for the child (15%) and (v) decreasing parental guilt/anxiety (8%). Less than half anticipated negative impacts; 74% expected that the most helpful result for their patient would be an abnormal result explaining the disorder. Among the 73 children for whom CMA was ordered, 81% got tested: 66% of the results were normal, 19% were abnormal and contributed to explain the condition and 12% were abnormal but of unknown significance. CONCLUSION: Paediatricians generally expect many positive and less negative impacts of genetic testing for children with developmental disorders. Parental perspectives are needed.
