SALSA MLPA Probemix P095 Aneuploidy detects the copy number of chromosomes 13, 18, 21, X and Y.
Contents: 36 MLPA probes, including 8 probes for each of the chromosomes 13, 18, 21, X and, 4 probes for the Y chromosome.
Tissue: genomic DNA isolated from human peripheral whole blood, or specified prenatal samples (see Intended Purpose).
Application: Patau, Edwards and Down syndromes, and Turner, Triple X, Klinefelter, and XYY syndromes.
IVDR certified and registered for in vitro diagnostic (IVD) use in selected territories.
This product has recently been CE-marked for in vitro diagnostic (IVD) use under the In Vitro Diagnostic Regulation (IVDR; EU 2017/746), which replaces the former CE-marking under the IVD Directive (IVDD; Directive 98/79/EC). This update was accompanied by a change in the intended purpose.
The SALSA MLPA Probemix P095 Aneuploidy is an in vitro diagnostic (IVD) or research use only (RUO) semi-quantitative manual assay for the detection of deletions or duplications of eight DNA sequences on each of four human chromosomes (13, 18, 21, X) and four sequences on chromosome Y as a means to detect an aneuploidy for one of these chromosomes in prenatal and postnatal DNA samples. For postnatal samples, genomic DNA isolated from human peripheral whole blood specimens can be used. For prenatal samples, genomic DNA isolated from (un)cultured amniotic fluid obtained in week 16 of the pregnancy or later and free from blood contamination, (un)cultured chorionic villi free from maternal contamination, or fetal blood can be used. P095 Aneuploidy is intended to confirm a potential cause for and clinical diagnosis of Patau, Edwards and Down syndromes (trisomy 13, 18 and 21, respectively) and Turner, Triple X, Klinefelter, and XYY syndromes (X/Y chromosome aneuploidies).
For the full intended purpose, see the product description.
The most frequent cytogenetic abnormalities at birth are aneuploidies, mainly trisomy of chromosomes 13, 18 or 21, and X/Y chromosome aneuploidies. The presence of an extra chromosome 13, 18 or 21, results in Patau, Edwards, or Down syndrome, respectively, which are all characterized in intellectual disability and other syndrome-specific features. Down syndrome is relatively common, occurring in approximately 1 in 700 live births. Edwards syndrome is seen in about 1 per 5,000 live births; Patau syndrome occurs between 1 in 10,000 to 21,700 live births. However, the overall occurrence of these syndromes at conception is higher due to the high frequency of fetal loss and pregnancy termination after prenatal diagnosis. The strongest risk factor for Patau, Edwards and Down syndrome is advance maternal age, as well as prior aneuploid pregnancy.
Sex chromosome abnormalities (SCAs) involve the presence of an extra or missing sex chromosome are more common and have less severe phenotypical consequences. The most common of the sex chromosomal aneuploidy syndromes are Turner (45,X), Klinefelter (47,XXY), Triple X (47, XXX), or XYY (or Jacobs syndrome; 47,XXY) syndromes. Turner syndrome prevalence is 1 in 2,000 to 5,000 female births and Klinefelter syndrome is seen in 1 per 650 male births. Triple X syndrome is seen in 1 per 1,000 female births while the prevalence of XYY syndrome is 1 in 1,000 male births. The triploid syndromes (69,XXX; 69,XXY and 69,XYY) are rare and the vast majority of pregnancies result in miscarriage or stillbirth. Sex chromosome aneuploidies are typically sporadic and arise from maternal or paternal meiotic errors.
SALSA MLPA Probemix P095 Aneuploidy is CE-marked under the IVDR for in vitro diagnostic (IVD) use in Europe. This assay is also registered for IVD use in Colombia, Israel and Morocco.
This assay is for research use only (RUO) in all other territories.

Inclusion of a positive sample is usually not required, but can be useful for the analysis of your experiments. MRC Holland has very limited access to positive samples and cannot supply such samples. We recommend using positive samples from your own collection. Alternatively, you can use positive samples from an online biorepository, such as the Coriell Institute.
The commercially available positive samples below can be used with the current (A4) version of this product.
