Diagnosis of lethal or prenatal‐onset autosomal recessive disorders by parental exome sequencing

Abstract: ObjectiveRare genetic disorders resulting in prenatal or neonatal death are genetically heterogeneous, but testing is often limited by the availability of fetal DNA, leaving couples without a potential prenatal test for future pregnancies. We describe our novel strategy of exome sequencing parental DNA samples to diagnose recessive monogenic disorders in an audit of the first 50 couples referred.MethodExome sequencing was carried out in a consecutive series of 50 couples who had 1 or more pregnancies affected … Show more

“…Many of us have counseled couples who have had pregnancies complicated by serious, and often fatal, fetal, or neonatal abnormalities in which there is no remaining biosample available to analyze. Now that whole exome sequencing is available to identify parental carriers of recessive conditions, this can enable a diagnosis in the proband and prenatal diagnosis in future pregnancies . Whilst it is clear that sequencing can have significant benefits, it also brings additional practical and ethical issues.…”

“…Now that whole exome sequencing is available to identify parental carriers of recessive conditions, this can enable a diagnosis in the proband and prenatal diagnosis in future pregnancies. 24 Whilst it is clear that sequencing can have significant benefits, it also brings additional practical and ethical issues. These are discussed in a series of articles initially published on-line in Prenatal Diagnosis in 2017 23,25,26 that will be the focus of our 2018 special topic issue.…”

“…However, this requires large quantities of high-quality DNA from the affected offspring. Access to sufficient quantity/quality of material is often limited, particularly in cases of fetal demise 12. An alternative approach is parental exome sequencing, which searches for rare, heterozygous variants occurring in the same gene in both parents.…”

“…An alternative approach is parental exome sequencing, which searches for rare, heterozygous variants occurring in the same gene in both parents. Despite being unable to identify de novo variants, this method had an overall success rate of 52% in a cohort of 50 couples 12. Although various sequencing approaches offer hope of rapid and non-invasive diagnosis, cost, feasibility and ethical issues require consideration before routine implementation of these in a diagnostic setting 15…”
