Assessment of parental disclosure of a 22q11.2 deletion syndrome diagnosis and implications for clinicians.

Most children with chromosome 22q11.2 deletion syndrome (22q11DS) have an IQ in the range that may allow them to be capable of understanding a genetic diagnosis despite mild intellectual disabilities. However, there are no publications that relate to the disclosure of a 22q11DS diagnosis to the affected child, or the factors that influence parents' disclosure to the child. A pilot study was conducted including eight semi-structured interviews with caregivers of children with 22q11DS, 10 to 17 years of age, to investigate the factors that influence how parents inform their children of the diagnosis. Six of eight participants had disclosed the diagnosis to the child, and most of these parents felt they could have benefited from additional advice from professionals to increase their confidence and success, as well as the child's comprehension of the information. Those who had not informed the child were uncertain about the words to use, how to initiate the conversation, or were concerned about the child's level of understanding. Our results demonstrate that genetics professionals should help prepare caregivers for conversations with their children about the diagnosis of 22q11DS, monitor the understanding of the diagnosis over time, and provide ongoing support.
