Genetic examinations list

Filter by name:

cfDNA test GENNET

Screening of cell-free foetal DNA (cfDNA) from the blood of a pregnant woman to detect aneuploidy of sex and non-sex chromosomes of the aborted foetus and its gender. From week 10 of the pregnancy.

Material:

Peripheral blood

Turnover Time:

2 weeks

STATIM

1 week

Cascade prenatal testing (by QF-PCR, array) excluding maternal contamination

Cascade aneuploidy testing of material after invasive prenatal examination using QF-PCR and array methods, excluding maternal contamination. This can be supplemented by foetal karyotyping, if necessary.

Material:

Chorionic villi, Amniotic fluid …
Chorionic villi, Amniotic fluid, Cord blood, Isolated DNA from chorionic villi, Isolated DNA from amniotic fluid, Isolated DNA from cordocentesis, DNA isolated from cultured cells

Turnover Time:

3 weeks

Smith-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).

Material:

Chorionic villi, Amniotic fluid …
Chorionic villi, Amniotic fluid, Cord blood, Isolated DNA from chorionic villi, Isolated DNA from amniotic fluid, Isolated DNA from cordocentesis, DNA isolated from cultured cells

Turnover Time:

3 weeks

STATIM

1 week

Clinical foetal exome (WES) (proband)

NGS analysis of exome (WES) and other clinically relevant regions of the foetal genome; we recommend simultaneously performing exome analysis also in the parents of the foetus – so-called trio analysis.

Material:

Chorionic villi, Amniotic fluid …
Chorionic villi, Amniotic fluid, Cord blood, Isolated DNA from chorionic villi, Isolated DNA from amniotic fluid, Isolated DNA from cordocentesis, Cultured cells, DNA isolated from cultured cells

Turnover Time:

6 months

STATIM

1 month

Cascade testing of the product of conception (by QF-PCR methods) excluding maternal contamination

Cascade aneuploidy testing of aborted foetal tissue using QF-PCR, arrays or karyotyping; excluding maternal contamination.

Material:

Conception product, DNA from the product of conception

Turnover Time:

3 weeks

cfDNA test GENNET (spontaneous abortion)

Screening of cell-free foetal DNA (cfDNA) from the blood of a pregnant woman to detect aneuploidy of sex and non-sex chromosomes of the aborted foetus.

Material:

Peripheral blood

Turnover Time:

2 weeks
