Neonatal Screening In Europe Revisited: An Isns-Perspective On The Current State And Developments Since 2010

Neonatal screening (NBS) was initiated in Europe during the 1960s with the screening for phenylketonuria. The panel of screened disorders ("conditions") then gradually expanded, with a boost in the late 1990's with the introduction of tandem mass spectrometry (MS/MS), making it possible to screen for 40-50 conditions in one blood spot. The most recent additions to screening programmes (screening for cystic fibrosis, severe combined immunodeficiency and spinal muscular atrophy) were assisted by or realised through the introduction of molecular genetics techniques. For this survey we collected data from 51 European countries. We report on the developments between 2010 and 2020, and highlight the achievements made during this period. We also identify areas where further progress can be made, mainly by exchanging knowledge and learning from experiences in neighbouring countries. Between 2010 and 2020, most NBS programmes in geographical Europe have matured considerably, both in terms of methodology (modernised) and with regards to the panel of conditions screened (expanded). These developments indicate that more collaboration in Europe through European organisations is gaining momentum. Only by working together can we accomplish the timely detection of newborn infants potentially suffering from one of the many rare diseases and take appropriate actions.
