Although GJB2/GJB6 genetic testing for non-syndromic hearing loss is available, there is no information regarding sharing of test results with family members. A qualitative study was conducted to elucidate if, how, and why parents of a child with hearing loss share GJB2/GJB6 test results with relatives. Parents whose child had testing (n = 7 positive, n = 4 negative, n = 1 inconclusive results) participated in a semi-structured interview and responses were analyzed using qualitative methods. All participants shared the test result with at least one relative, but selective non-disclosure also was observed. Reasons for, and reactions to, sharing were diverse and differed as a function of test result. In comparing the results from this study to published literature, similarities and differences were identified with regards to disclosure of genetic test results for hearing loss versus other conditions. Differences suggest that hearing loss may have unique attributes that influence responses to genetic test information. Further research is needed to replicate these findings.
虽然可以进行非综合征性听力损失的GJB2/GJB6基因检测,但关于与家庭成员分享检测结果的信息却没有。开展了一项定性研究,以阐明听力损失儿童的父母是否、如何以及为何与亲属分享GJB2/GJB6检测结果。其孩子接受检测的父母(7例阳性、4例阴性、1例结果不确定)参与了半结构化访谈,并采用定性方法对回答进行了分析。所有参与者都与至少一名亲属分享了检测结果,但也观察到了选择性不披露的情况。分享的原因和反应各不相同,并因检测结果而异。在将本研究结果与已发表文献进行比较时,确定了听力损失基因检测结果与其他疾病检测结果披露方面的异同。差异表明,听力损失可能具有独特的属性,会影响对基因检测信息的反应。需要进一步研究来重复这些发现。
