2. Main business or product introduction during the reporting period (I) the main business of the company is gene testing services and sales of equipment and reagents based on high-throughput sequencing technology. Focusing on "medical products and services", the company has formed a business system focusing on the application of "Genetics" and continuously expanding to the field of "big data". Specific products and services are as follows: 1. Medical products and services 1) genetics
The company mainly provides reproductive health and genetic disease gene testing products and services covering the tertiary prevention of birth defects: the primary prevention field mainly carries out carrier screening gene testing before and during pregnancy, including spinal muscular atrophy (SMA) gene testing, fragile X syndrome carrier screening (FXS), folate metabolism gene testing, genetic deafness gene testing, etc, At the same time, carry out "Ke yun'an" preimplantation genetic test (PGT) in the field of assisted reproduction; In the field of secondary prevention, we mainly carry out "bebian" noninvasive prenatal gene testing (NIPT) for chromosome aneuploidy screening and "bebian plus" noninvasive prenatal testing (NIPT plus) for 100 chromosome diseases and genomic diseases screening. At the same time, we also carry out "konoan" chromosome copy number variation detection (CNV SEQ) in the field of prenatal diagnosis and abortion genetics etiology detection; In the field of tertiary prevention, we mainly carry out whole exome sequencing (WES) and whole genome sequencing (WGS). Relying on the third-generation sequencing technology, the company carries out "screening for carriers of thalassemia" (third-generation thalassemia). The third-generation thalassemia has irreplaceable advantages in improving the prevention and control efficiency of severe thalassemia, avoiding unnecessary prenatal diagnosis caused by misscreening and clinical accurate genetic counseling. List of main products of genetic application:
Name test item application field sample test content
Noninvasive prenatal gene detection of 13, 18 and 21 fetal chromosomal aneuploidy in peripheral blood of reproductive healthy pregnant women
（NIPT）
Bebian plus noninvasive prenatal gene detection 17 fetal chromosome aneuploidies including 13, 18, 21 and sex chromosome aneuploidy (NIPT pus) in the peripheral blood of reproductive healthy pregnant women 76 kinds of fetal chromosome large fragment microdeletion and microcoincidence syndrome greater than 10MB and 7 kinds of relatively high incidence of microdeletion diseases located at the location of chromosome fragments related to specific syndrome
Konoan chromosome copy number variation detection reproductive health, amniotic fluid, umbilical cord blood, one-time analysis of 23 pairs of chromosome aneuploidy and 100 (CNV SEQ) transmission detection of abortion, peripheral KB chromosome copy number variation (CNVs)
Blood, etc
Keyun'an preimplantation genetics test reproductive health blastomere single-cell chromosome aneuploidy, microdeletion microdeletion (PGT) greater than 10MB or blastocyst trophoblast coincidence and unbalanced translocation
Cells
The safe exon group of Beiquan is used to detect reproductive health, peripheral blood and abortion exons (the collection of Wes transmission detection tissues and DNA in all exon regions of the genome), which is conducive to the detection of gene variation and improve the diagnosis rate of genetic diseases. It is applied to ophthalmology, cardiovascular system Neurological diseases, endocrinology, metabolism, orthopedics, respiration, kidney, blood, immunity, digestion, skin and pediatrics
Using the third-generation sequencing technology to promote reproductive health and peripheral blood, the third-generation poverty can cover more than 30 kinds at one time α There are more than 28 kinds of screening diseases in thalassemia carriers β Missing variation, exceeding all previous methods of poverty detection; Can accurately detect α Gene multi copy variation, help α Multi copy merge β Precise prevention and control of "class III" land poverty with genetic variation; Be able to accurately identify Hong Kong type and anti Hong Kong type variants to avoid misscreening; It can realize the accurate identification of CIS and trans variants in place at one time, without family verification, and reduce the back and forth of pregnant women and their families.
For the rare type of thalassemia whose cause cannot be determined by conventional gene detection methods, the third generation of thalassemia can improve the diagnostic efficiency by 40-60%; For the false positive and false negative of traditional PCR and second-generation thalassemia, it can also be verified by third-generation thalassemia
Screening the copy number of exon 7 of SMN1 gene and the number of CGG repeats in the regulatory region of FMR1 gene in reproductive healthy peripheral blood of SMA and FXS carriers with propranolol
Detection of nine hot spot genes in reproductive healthy peripheral blood (GJB2, SLC26A4 (PDS)
Gjb3, 12S rRNA, KCNQ4, Coch, pou3f4, GJB6, tmie)
Detection of folate metabolic capacity gene of Berean: C677T and A1298C sites of 5,10-methylenetetrahydrofolate reductase (MTHFR) gene and A66G site of methionine synthase reductase (MTRR) in reproductive healthy peripheral blood
2) Reagent sales gene sequencing requires the use of reagent groups such as DNA extraction reagent, DNA purification reagent, library building reagent and sequencing reagent. NIPT database building reagent of the company applies the self-developed ez-palo rapid database building method, which can easily and quickly complete the database building. The main reagent products of the company are shown in the table below:
