HEREDITY Autosomal Recessive
CLINICAL AREA The SMA gene region on chromosome five contains the telomeric SMN1 and centromeric SMN2 genes. SMN1 gene deletion is seen in 95% of SMA cases. While the copy number of the SMN2 gene alone has no clinical significance, in cases with SMN1 deletion, the copy number of the SMN2 gene affects the phenotype.
METHOD Next Generation Sequencing
