This study aims to assess the impact of prenatal diagnosis of de novo apparently balanced chromosome rearrangements (ABCRs) on maternal stress, family functioning and maternal plans of disclosure of genetic information to their child.
All liveborn children with prenatally detected de novo ABCRs in two Australian states over a 10-year period (1994-2003) were retrospectively ascertained. Of 39 eligible cases, 16 (41%) participated in the study. Mothers of these children completed a questionnaire using standardized measures to assess family functioning, parental distress, parent-child interaction and child characteristics, with open-ended questions regarding disclosure.
The majority of mothers appeared to experience normal levels of parenting stress, quality of parent-child interaction and healthy family functioning. However, most mothers recalled experiencing a significant degree of worry at the time of receiving their prenatal test results, and some mothers (4/15) reported receiving uncertain or conflicting results. Most mothers (13/15) conveyed an understanding of the importance of disclosing this genetic information to their child, and 12/15 conveyed their intention to make this disclosure.
Most mothers reported normal parenting stress and family functioning, despite experiencing significant worry upon receiving results. Some children are at risk of nondisclosure of their carrier status.
