Karyotyping in gamete donation candidate
It is used to determine karyotype by classical cytogenetic methods to determine numerical and structural chromosomal aberrations (deviations) of the gamete donor.
Material:
Peripheral bloodTurnover Time:
8 weeksSTATIM
4 weeksCarrierTest – preconception panel of donor candidate (carriage of recessive mutations)
Testing for the hidden carriage of key mutations in recessive genes that may affect the health status of carriers and their offspring. CarrierTest intended for donors is a panel NGS test of selected regions using data from exome libraries.
Material:
Peripheral blood, Isolated DNA from bloodTurnover Time:
4 weeksSTATIM
2 weeksAdditional evaluation of selected gene from CarrierTest panel for matching
Additional testing for hidden carriage of key mutations in selected recessive genes that may affect the health status of carriers and their offspring. The matching uses the evaluation of data from the already performed CarrierTest NGS testing intended for donors. When to use this test: We use it to match the donor with the partner who carries the mutation in the selected gene to determine the suitability of using this donor and eliminate any reproductive risk.
Material:
Isolated DNA from bloodTurnover Time:
2 daysSTATIM
1 dayCystic fibrosis – 50 mutations + Tn variants of IVS8 in the CFTR gene
Testing for the 50 most common CFTR gene mutations and determination of polymorphism in intron 8 (IVS8 Tn/TGn). These 50 mutations represent over 92% of the findings in patients diagnosed with CF in the Czech population using fragmentation analysis.
Material:
Peripheral blood, Isolated DNA from bloodTurnover Time:
3 weeksSTATIM
3 daysSpinal 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 daysAR deafness – detection of 35delG GJB2 mutation
Testing for 35delG mutation in the GJB2 gene responsible for AR hereditary, non-syndromic disorder/hearing loss (deafness).
