SMN1 gene copy number analyses for SMA healthy carriers in Italian population.

Abstract

The routine molecular test for spinal muscular atrophy (SMA) diagnosis is based on the detection of a homozygous deletion of exons 7 and 8 of the telomeric copy of the survival motor neuron gene (SMN1). The presence of the centromeric copy of the SMN gene (SMN2) does not allow the detection of the hemizygous absence of the SMN1 gene, which characterizes the… (More)
