World Down Syndrome Day-Be with us, not for us

21 March 2023 is the 12th World Down Syndrome Day.'s theme this year, "With Us Not For Us," aims to be grounded in human rights so that people with Down syndrome have the right to be treated fairly and have the same opportunities as others to work with others to improve their lives..
name March 21 as Down Syndrome Day? Because people with Down Syndrome have three chromosomes 21. Children with Down syndrome are also known as "baby Tang".

What is Down Syndrome?

Down syndrome (DS) is a commonchromosomal abnormalities Birth defectsdisease. Humans have total.23 pairs of chromosomes, each pair of two, a total of 46. Down's syndrome is when chromosome 21 changes from two to three..
According to the China Birth Defects Prevention Report (2012) "shows that there are currently 1 million patients with Down's syndrome in my country, with 2.3-25000 new cases every year, and an average of one" baby Tang "is born every 20 minutes. The main manifestations of patients are mental retardation, developmental retardation, multiple deformities, special faces, and unable to take care of themselves completely..
Down'sSyndromeis an episodic disease,namelyevery healthy couple hasmaybirth"Tang Baobao".

How to Prevent Down Syndrome

and effective prenatal screening is the most effective measure to prevent and treat Down syndrome. Currently, prenatal screening for Down's syndrome includes Down's screening and noninvasiveDNA Prenatal ScreeningTechnology.

Down's screening, that is, the fasting venous blood of pregnant women, the determination of biochemical markers in serum, combined with the age of pregnant women, gestational weeks, weight, etc., to calculate the occurrence of Down's syndrome in the fetusvalue. The detection rate of this technology isabout 70%, there is a false positive rate of about 5%.
non-invasiveDNA prenatal screening technology,is pumpingvenous blood of pregnant women, usinghigh throughputsequencingDNA fragments (including cell-free fetal DNA) for sequencing,thenbioinformatics analysis to detect three chromosomal disorders in the fetus(with Down syndrome). The technology has a high detection rate, upmore than 95%, the false positive rate of low characteristics.

Serena based on amplicon sequencing technology

non-invasiveDNA Prenatal Screening

SerenaAssuriT-Anon-invasiveDNA Prenatal Screeningproduct, unique technical solution, based on amplicon sequencing technology. AfterMulti-center, Prospective, Large-scale Clinical Trial Proving, the detection technology compared to traditional genome sequencing-based non-invasiveDNAdetection technology,has higher accuracy and positive predictive value.
and compared to genome sequencing technologies, amplicon sequencing increases the proportion of sequences from the target chromosome.10 times more. Inusing the same sequencing platform, the amount of samples that can be carried by one sequencing can be increased several times,greatly saves sequencing costs and is more suitablethe whole population of pregnant womenNIPT screen.

Finally, since the average coverage of a single detection site is as high500x, the discrimination of maternal and fetal DNA can be achieved by SNP sites, and the fetal DNA ratio can be accurately calculated. The proportion of fetal DNA is the most important quality control index of NIPT, and its accurate determination is essential to further advance the detection window of NIPT.. Therefore, the product can be used inpregnant women during early pregnancy.
