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).

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.

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:
