Newborn screening for spinal muscular atrophy: The views of affected families and adults
The views of patients and families on newborn screening for Spinal muscular atrophy (SMA) is presented in the American Journal of Medical Genetics. The authors state that SMA is one of the leading genetic causes of infant death worldwide and the views of affected families on newborn screening for this condition has been overlooked. The majority (70%) of participants interviewed by the authors were in favour of newborn screening, but preferred preconception and/or prenatal screening. According to the interviewees newborn screening would improve support and may have the possibility of enrolling pre-symptomatic children to clinical trials to find a cure. The minority of participants who did not support newborn screening reasoning that they were concerned about its impact on the early experiences of the family and whether it was in the child's interest to diagnose an untreatable disease at birth.
Expanded carrier screening in a reproductive context: An advisory report by the Superior Health Council of Belgium
In this advisory report, the Superior Health Council (SHC) of Belgium provides recommendations on the “criteria that need to be applied in preconceptual genetic testing for severe autosomal and X-linked recessive diseases for couples planning a pregnancy.”
The recommendations are meant for healthcare authorities and professionals and cover scientific and ethical issues to be considered in this context.
They provide 6 recommendations:
- “The SHC considers that knowledge of a person’s carrier status can provide benefit in a reproductive context.
- The SHC considers that expanded carrier screening should be offered preconceptionally as this allows more reproductive options, and has less time constraints, resulting in less emotional distress than if the test were performed during the pregnancy.
- The SHC considers that carrier screening panels should include disorders and mutations based on specific criteria (I. severity, II. age of onset, III. prevalence, IV., selection of mutations based on clinical significance, V. treatability).
- Considering the role of professionals such as gynecologists and general practitioners in guiding pregnant women or in guiding families planning a pregnancy, these professionals are well placed to inform about carrier screening or to follow up requests for carrier screening.
- The SHC believes that the most affordable strategy for identifying at-risk couples is screening both partners.
- As for any medical intervention, participation in carrier screening implies an informed and voluntary participation.
- The SHC also recognizes that stakeholder involvement about carrier screening should take place.
- The SHC recommends a stepwise introduction of the carrier screening as the implementation of carrier screening as a reproductive choice may imply considerable adaptation of current services and practices or even require novel types of services.”
