Abstract:
Spinal muscular atrophy (SMA), an autosomal recessive neuromuscular disease with a carrier frequency of 1/60 ~ 1/40, is characterized by severe clinical symptoms, high mortality rate, and expensive treatment costs. Carrier screening is of paramount importance to detect high-risk couples, and therefore to reduce the occurrence of SMA. In China, SMA carrier screening has become widespread, though there is still a lack of genetic counseling expertise. This article has focused on the current challenges for SMA carrier screening, including the screening methods, target population, screening procedures, and pre-/post-testing counseling. The aim is to standardize its application and counseling in the clinical practice.
