Pregnancy Screening Cystic fibrosis gene screening

CYSTIC FIBROSIS –  NEOSCREEN TESTING GENETIC SCREENING
WHAT IS

Cystic fibrosis is the second most common serious hereditary disease to newborns.

BASIC APPEARANCES – INDICATIONS – IMPORTANCE

The disease in most cases can be expressed if the same gene mutations are combined by both parents.

Reports show that 1 in 25 people are carriers of a cystic fibrosis mutation in the European population. In the absence of relevant prenatal screening, 1 in 2,000 to 3,000 newborns is expected to suffer from this serious disease.

For Greece, it is estimated that the mutations carriers are 500,000 prople, classifying for most doctors the genome examination at prenatal level, necessary.

 

Its effects on the child born with the disease are severe in the functioning of the lungs, the pancreas, the liver and the intestine. Despite the recent developments in medical treatment of the disease, the average life of people with cystic fibrosis is significantly reduced (in a Canadian survey estimated <50 years )

 

GENE SCREENING

Gene Screening tests for cystic fibrosis gene are offered inf four levels:

1) F508del Mutation

This mutation is the most common based on literature, responsible for about 50% of cases of the disease.

2) Gene panel for 89% CFTR cases

It is the most commonly sought mutation detection test kit and is made by analysis of 186 independent alleles of the CFTR cystic fibrosis gene.

It is reported bibliographically, that in the general population of cases of the disease, the coverage rate with this particular panel is 89%.

3) Pannel CF 99.6%

It is the most modern analysis of genes for cystic fibrosis with analysis of 1700 independent alleles of the CFTR cystic fibrosis gene.

It is reported bibliographically, that in the general population of cases of the disease, the coverage rate with this particular panel is 99.6%.

 

Important

It is always important to consult a qualified health professional before doing any genetic testing to make sure you fully understand the conditions being tested and the explanation of the results
