Tepnel Life Sciences PLC Announces New DNA Test for Early Detection of Familial Hypercholesterolaemia
Published: Aug 27, 2008
FH is a public health problem throughout the world with an estimated 10 million people affected, the majority of who will suffer an adverse coronary event before they are 65 years old. A common genetic disorder, the potentially lethal condition occurs in 1 of 500 people in Europe and North America. In the United Kingdom it is estimated that up to 110,000 people are affected with FH and 75% of these cases are undiagnosed.
The NICE consultation on a draft of guidelines for use by the National Health Service (NHS) in England and Wales is now being finalized with anticipated publication for August, 2008. NICE is expected to recommend that all FH patients are offered a DNA test with subsequent cascade screening to be performed where the mutation is identified in a patient.
In a recent UK pilot study the test identified a 52% mutation detection rate in a sample of 110 FH heterozygous patients. “The study findings validate Elucigene FH20 as a valuable component for future FH screening programs in the United Kingdom, providing a cost-efficient and simple method for confirming a person has inherited this deadly condition,” said Ben Matzilevich, Tepnel’s Chief Executive Officer. “For effective treatment, early identification of persons with FH is essential and FH20 offers the NHS the right tool at the right time to implement the new clinical practice guidelines.”
Currently late-stage clinical indications that suggest a patient is affected with FH are increased serum cholesterol concentration, tendon xanthomas and premature coronary heart disease. Treatment with statins to lower cholesterol levels is effective, but preventative treatment requires early diagnosis. Pre-symptomatic identification of FH individuals can ensure the health risks of high cholesterol are minimized through appropriate modifications to diet and lifestyle.
Early detection requires identification of genetic mutations of the low-density lipoprotein receptor (LDLR) gene, the apoloiprotein B-100 (Apo B) gene or the proprotein converatse subtilisin/kexin type 9 (PCSK9) gene which are the cause of FH. Unlike other genetic diseases such as cystic fibrosis, where an affected patient must inherit two copies of the mutated gene, FH has an autosomal dominant pattern of inheritance and requires the affected patient to carry only one copy of the mutated gene.
While such DNA analysis and mutation detection is crucial for the definitive diagnosis of FH, the testing can be tedious and expensive due to the extremely heterogeneous nature of the LDLR gene.
Following the confirmation of mutation status of an FH patient using the rapid and cost-effective Elucigene FH20 assay, the new Tepnel test can be used to detect other previously undiagnosed family members with FH through cascade screening programs.
The Elucigene FH20 test is developed and manufactured within quality systems accredited to ISO9001 and ISO13485 and complies with the European Community Directive 98/79/EC. The test is not for use in diagnostic procedures in the USA.
