Direct-to-consumer personal genomic testing (DTC-PGT) results lead some individuals to seek genetic counseling (GC), but little is known about these consumers and why they seek GC services. We analyzed survey data pre- and post-PGT from 1026 23andMe and Pathway Genomics customers. Participants were mostly white (91%), female (60%), and of high socioeconomic status (80% college educated, 43% household income of ≥$100,000). After receiving PGT results, 43 participants (4%) made or planned to schedule an appointment with a genetic counselor; 390 (38%) would have used in-person GC had it been available. Compared to non-seekers, GC seekers were younger (mean age of 38 vs 46 years), more frequently had children <18 (26% vs 16%), and were more likely to report previous GC (37% vs 7%) and genetic testing (30% vs 15%). In logistic regression analysis, seeking GC was associated with previous GC use (OR = 6.5, CI = 3.1-13.8), feeling motivated to pursue DTC-PGT for health reasons (OR = 4.3, CI = 1.8-10.1), fair or poor self-reported health (OR = 3.1, CI = 1.1-8.3), and self-reported uncertainty about the results (OR = 1.8, CI = 1.1-2.7). These findings can help GC providers anticipate who might seek GC services and plan for clinical discussions of DTC-PGT results.
直接面向消费者的个人基因组检测(DTC-PGT)结果致使一些人寻求遗传咨询(GC),但对于这些消费者以及他们寻求遗传咨询服务的原因却知之甚少。我们分析了来自1026名23andMe和Pathway Genomics客户在接受PGT前后的调查数据。参与者大多为白人(91%)、女性(60%),且社会经济地位较高(80%拥有大学学历,43%家庭收入≥10万美元)。在收到PGT结果后,43名参与者(4%)已经预约或计划预约遗传咨询师;若有面对面的遗传咨询服务,390人(38%)会选择使用。与未寻求遗传咨询的人相比,寻求遗传咨询的人更年轻(平均年龄38岁对46岁),有18岁以下子女的比例更高(26%对16%),并且更有可能报告曾接受过遗传咨询(37%对7%)和基因检测(30%对15%)。在逻辑回归分析中,寻求遗传咨询与之前接受过遗传咨询(OR = 6.5,CI = 3.1 - 13.8)、因健康原因有动力进行DTC-PGT(OR = 4.3,CI = 1.8 - 10.1)、自我报告健康状况为一般或较差(OR = 3.1,CI = 1.1 - 8.3)以及对结果自我报告存在不确定性(OR = 1.8,CI = 1.1 - 2.7)有关。这些发现有助于遗传咨询服务提供者预测哪些人可能寻求遗传咨询服务,并为DTC-PGT结果的临床讨论做好准备。
