Abstract

BACKGROUND: The introduction of a comprehensive newborn screening program for spinal muscular atrophy (SMA), specifically for 5q-SMA, is planned for the end of 2021 in Germany. Several targeted treatment options have become available for all patients with SMA.

MATERIAL AND METHODS: Newborn screening for 5q-SMA is based on the detection of a homozygous deletion of exon 7 in the SMN1 gene by molecular genetic analysis from the dried blood card. In all cases a second blood sample must be drawn as a part of confirmation diagnostics including the determination of the SMN2 copy numbers.

RESULTS: Insights from pilot projects performed in parts of Germany are presented. Advantages and disadvantages of the screening project are discussed.

CONCLUSION: Consultation and treatment should be carried out in a department of neuropediatrics with experience in the treatment of children with 5q-SMA, which is able to provide all current treatment options for the child, so that, when necessary, the treatment can be started within the first month of life.
