“Our INNO-LiPA® CFTR assays are appreciated for their outstanding performance in clinical laboratories across the world today. To fulfill new regulations and local guidelines applied in different European countries we have decided to add the INNO-LiPA CFTR Extra assay to our portfolio” said Christiaan De Wilde, CEO of Fujirebio Europe. “With this new product we offer in total 88 disease-causing mutations and optional poly T testing, increasing the overall detection rate for cystic fibrosis to at least 91,8%.”
About cystic fibrosis
Cystic fibrosis is one of the most frequent human genetic disorders, predominantly affecting individuals of Caucasian descent in North America and Europe. With about 1 in 25 persons carrying the autosomal recessive genetic mutation responsible for this potentially life-threatening condition, it is no surprise that the disease occurs with a frequency of 1 in every 2500 to 3000 live births.
Cystic fibrosis is caused by mutations in the cystic fibrosis transmembrane conductance regulatory (CFTR) gene, which is located on the long arm of chromosome 7. This genetic abnormality causes defective chloride transport across cell membranes, leading to the formation of thick, viscous mucus gland secretions (hence the alternative name for the disease: mucoviscidosis). These sticky secretions clog the ducts of various glands, especially those of the pancreas and lungs, giving rise to pancreatic insufficiency and repeated respiratory tract infections which, together with salty sweat, are the hallmarks of the classical presentation of the disease.
Diagnosis of cystic fibrosis
The telltale signs and symptoms of cystic fibrosis are typically observed first in neonates or young children. Early diagnosis of cystic fibrosis will trigger close follow-up and fast implementation of a selected treatment and nutrition program to prevent irreversible tissue damage. This is an essential factor which determines the quality of life and the life expectancy of the cystic fibrosis patient.
Already within 24 hours after birth, some 15% of children present with meconium ileus (intestinal obstruction). Others fail to gain weight and thrive, while a significant proportion of children develop increasingly menacing respiratory symptoms. These clinical presentations, along with the abnormal results of an immunoreactive trypsin (IRT) test, a pancreatitis associated protein (PAP) test, and/or sweat test, direct the physician towards a diagnosis. However, the definitive diagnosis of cystic fibrosis is made upon genetic analysis of the CFTR gene.
Other diseases, which are clinically defined as atypical cystic fibrosis, are also associated with CFTR mutations. Examples of these conditions are atypical asthma, bronchiectasis, pancreatitis, and male infertility caused by the congenital absence of the vas deferens (CBAVD). A molecular analysis of the CFTR gene is recommended for purposes of differential diagnosis.
Genetic testing should always be offered along with appropriate genetic counselling.
