A new rapid turnaround genetic test for spinal muscular atrophy (SMA), found to reduce time to results from 21 days to 4 days, will be offered at no charge to qualified individuals in the United States as part of the SMA Identified program. This according to a press release from Biogen Inc and Invitae Corporation.

SMA STAT (Biogen Inc; Invitae Corporation) is a rapid genetic test designed to detect deletions in the SMN1 gene and to assess the copy number of the SMN2 gene in individuals with a suspected diagnosis or family history of SMA. The test was found to reduce the time needed confirm a definitive diagnosis of SMA and enable clinicians to expedite treatment plans.

He also noted, “Whether an infant or child is showing early signs of SMA or a long-standing patient requires genetic confirmation of the disease, every day makes a difference.”
