Sequencing of the ABCA1 gene
||2-4 ml of blood with anticoagulant EDTA
1 µg DNA in TE, AE or pure sterile water at 100-250 ng/µl
The A260/A280 ratio should be 1.8-2.0. DNA sample should be run on an agarose gel as a single band, showing no degradation, alongside with a quantitative DNA marker.
Indications for genetic testing:
1. Confirmation of clinical diagnosis
2. Differential diagnosis
3. Genetic counceling
Tangier disease is characterised by hypocholesterolaemia, extremely low or absent level of HDL cholesterol, modestly decreased LDL cholesterol and elevated triglycerides in plasma.
The major clinical signs of Tangier disease include hyperplastic yellow-orange tonsils, hepatosplenomegaly, and peripheral neuropathy. Rarer complications may include corneal opacities that typically do not affect vision, premature atherosclerotic coronary artery disease, and mild hematologic manifestations, such as mild thrombocytopenia, reticulocytosis, stomatocytosis, or hemolytic anemia.
Tangier disease is inherited in an autosomal recessive manner. Tangier disease is caused by variants in the ABCA1 gene. Global prevalence of the disease is 1:640 000.

Next-generation sequencing (NGS) technologies have improved throughout the years as rapid, high-throughput and cost-effective approaches to fulfil medical sciences and research demands. Asper Biotech has now implemented Illumina MiSeq to it’s routine workflow and offers a variety of NGS services in it’s CLIA certified laboratory. The list of services can be found from Asper Biotech’s page here. Our highly experienced scientific team as well as medical doctors are here to deliver you the results for both scientific and medical diagnostic projects. Just contact info[at]asperbio.com for more information.
Genetic testing company Asper Biotech has been acquired by Asper Biogene LLC and hereafter will be operating under the name of Asper Biogene. The deal was concluded in July 2017 to enhance the testing services and expand into new markets. The company is maintaining its focus on diagnostics for rare and common hereditary diseases.
Our testing menu has become one of the most comprehensive in the clinical diagnostics field. Starting with tests for eye diseases, we have broadened the testing scope, which now encompasses to neurological, cardiological, oncological, hematological etc. areas. Besides our best-known portfolio – Asper Ophthalmics seven new testing portfolios have been launched. As our aim is to provide flexible and customer-friendly services, our clients are always encouraged to ask for customized tests and testing solutions.
Our laboratory is an authorized medical laboratory, CLIA (#99D2046227), ISO 15189:2012, and ISO 9001:2015 certified. We are participating in the European Molecular Genetics Quality Network (EMQN) quality assessment schemes in order to deliver genetic services at the highest level of quality standards.
Our clients, including leading university hospitals, private clinics, commercial laboratories and research organisations are from more than 40 countries. Development and elaboration of new tests are continuous processes in our daily practice to meet the customers’ needs and provide testing services to more patients and healthcare providers. We are also offering custom-test development with complete workflow and full customer support.
Besides providing genetic diagnostic services, we are an appreciated scientific partner for many international R&D projects due to our innovation-driven approach and long-lasting experience. We have had successful collaboration with different funding agencies supporting R&D activities, which have led to technological improvements and moreover to state-of-the-art genetic tests. Our expertise is widely recognized by participation in numerous European-wide research projects where we have been incorporated as an essential partner.
About Asper Biotech
Asper Biotech was established in 1999 as a spin-off of the University of Tartu. Since then Asper Biotech quickly became a leading Estonian biotechnology exporter due to its extensive services and the quality of the results.
