Preference for secondary findings in prenatal and pediatric exome sequencing
Beschreibung:
<jats:title>Abstract</jats:title><jats:sec><jats:title>Objective</jats:title><jats:p>We aimed to determine the frequency of accepting secondary findings in families undergoing exome sequencing in prenatal and pediatric settings.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>This was a secondary analysis of prospectively enrolled patients undergoing trio exome sequencing for congenital anomalies or developmental disorders in prenatal and pediatric settings, in which families were offered receiving secondary findings (initially assessed in the proband and, if identified, then in the parents). The primary outcome was frequency of accepting secondary findings. Secondary outcomes included frequency of acceptance in prenatal versus pediatric settings, and sociodemographic differences between those who accepted versus declined secondary findings.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>There were 682 families included in the cohort (289 prenatal and 393 pediatric). Overall, 84% (576/682) of families accepted secondary findings: 86.2% (249/289) of families undergoing prenatal versus 83.2% (327/393) pediatric (<jats:italic>p</jats:italic> = 0.30) testing. Secondary findings were identified in 2.6% (15/576) of cases, with no difference between prenatal and pediatric settings. There were no differences in sociodemographics between families that accepted versus declined secondary findings.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>The majority of families undergoing exome sequencing accepted secondary findings; this did not differ in prenatal versus pediatric settings. This highlights the need for guidance surrounding the offer of secondary findings in the prenatal setting.</jats:p></jats:sec>
