Spinal muscular atrophy – determination of copy number of exon 7 and 8 in the SMN1 gene
Examination of SMN1 and SMN2 genes associated with spinal muscular atrophy (SMA) by MLPA method. This concerns an autosomal recessive disease that is most often associated with homozygous deletion of exon 7 in the SMN1 gene (almost 95% of all patients with SMA).

3 daysSmith-Lemli-Opitz syndrome – detection of the 3 most common mutations in the DHCR7 gene (p.Trp151Ter, p.Val326Leu and c.964-1G>C)
Screening of the 3 most common DHCR7 gene mutations: c.452G>A (p.Trp151Ter), c.976G>T (p.Val326Leu), c.964-1G>C (IVS8-1G>C) using Sanger sequencing, which represent about 81% of all mutations in patients with SLOS (Smith-Lemli-Opitz syndrome, OMIM 270400).
