At IntroLab Belgrade<\/a>, we offer molecular testing for SMA (SMN1 gene, exon 7)<\/strong> to accurately assess carrier status for spinal muscular atrophy. This analysis identifies deletion of exon 7 in the SMN1 gene, the genetic change responsible for most cases of SMA. A person can be entirely healthy and have no symptoms while still carrying a mutation that may be passed on to their child. That is why carrier screening represents an important step in informed and responsible family planning.<\/strong><\/p>\n

What is Spinal Muscular Atrophy?<\/h2>\n

Spinal muscular atrophy is a hereditary neuromuscular disorder caused by changes in the SMN1 gene.<\/strong> This gene is essential for producing a protein that enables the normal function of motor neurons \u2014 the nerve cells responsible for controlling muscle movement.<\/p>\n

The condition is inherited in an autosomal recessive pattern<\/strong>, meaning a child can develop the disease only if both parents carry the mutation.<\/p>\n
