The GT SMA Detector is a SMA Carrier Screening Kit and accurately detects deletion of exon 7 of SMN1 gene. The kit is Real Time PCR based and can accurately determines if a sample is normal, carrier or affected by determining presence or absence of exon 7 of the SMN1 gene. Also, GT AneuSure Plus, Max Plus and Extra Plus kits can detect absence of exon 7 of SMN1 or SMN2 genes, though the SMN1 detection is based on multiplex PCR and capillary electrophoresis.
