Genetic examinations list

Filter by name:

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 blood

Turnover Time:

3 weeks

STATIM

3 days

AR deafness – detection of 35delG GJB2 mutation

Testing for 35delG mutation in the GJB2 gene responsible for AR hereditary, non-syndromic disorder/hearing loss (deafness).

Material:

Peripheral blood, Isolated DNA from blood

Turnover Time:

3 weeks

STATIM

3 days

Response to hormonal stimulation – Ser680Asn polymorphism in the FSHR FSHR gene

Testing for p.Ser680Asn polymorphism in the FSH receptor gene (FSHR) by real-time PCR. This is aimed at investigating the Ser680Asn to Ser680Ser change that is associated with low sensitivity of FSHr to gonadotropins.

Material:

Peripheral blood, Isolated DNA from blood

Turnover Time:

3 weeks

STATIM

3 days

PGT preparation, female patient

DNA testing of the female patient by karyomapping (SNP array) to determine the parental origin of chromosome segments in the examined embryos and to possibly detect various types of genetic disorders, including monogenic ones.

Material:

Peripheral blood, Buccal swab …
Peripheral blood, Buccal swab, Isolated DNA from blood

Turnover Time:

4 weeks

STATIM

2 weeks

PGT preparation, partner

DNA testing of the patient’s partner by karyomapping (SNP array) to determine the parental origin of chromosome segments in the examined embryos and to possibly detect various types of genetic disorders, including monogenic ones.

Material:

Peripheral blood, Buccal swab …
Peripheral blood, Buccal swab, Isolated DNA from blood, Isolated DNA from chorionic villi, Isolated DNA from amniotic fluid, Isolated DNA from cordocentesis, DNA isolated from the product of conception

Turnover Time:

PGT – aneuploidy (PGT-A)

Preimplantation genetic testing of aneuploidy in embryos by NGS method to assess their suitability for transfer and exclude non-viable embryos.

Material:

Trophectoderm, Amplified DNA from the trophectoderm

Turnover Time:

4 weeks
