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).
Material:
Peripheral blood, Isolated DNA from bloodTurnover Time:
3 weeksSTATIM
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).

1 weekStereocilin gene fragmentation analysis
Targeted testing for STRC gene deletion by QF-PCR (Stereocilin gene) responsible for hearing impairment DFNB16.

3 daysHLA-C (C1/C2) Genotyping
HLA-C typing at the allelic resolution level is used for the detailed determination of HLA-C gene variants. This gene plays a crucial role in the communication between the mother's immune system and the developing embryo during pregnancy. HLA-C analysis helps identify specific combinations of maternal and fetal genes that may be associated with a higher risk of complications such as recurrent miscarriages, preeclampsia, intrauterine growth restriction (IUGR), or preterm birth. We recommend combining it with the KIR haplotype determination method.
