Preconception genetic testing for couples and gamete donors
The carrier screening panel is a genetic test that simultaneously analyses mutations in 420 genes which cause recessive and x-linked inherited pathologies. Diseases with a recessive inheritance pattern, like cystic fibrosis, are those in which the affected subject inherits two mutations, one from each healthy carrier parent. The theoretical risk for these couples is 25%.
Our new panel includes in a single test:
The purpose of this test is to know if a person is a healthy carrier of gene mutations related to recessive genetic diseases. The knowledge of someone having a carrier status is extremely valuable to determine the specific reproductive risk and to program suitable medical action aimed at avoiding such risk.
a.- General population: couples without a personal or familial genetic disease background who, in a preconceptional context, wish to know their risk of conceiving a child affected by a specific recessive inherited disease.
b.- Consanguineous couples, who have an increased risk of recessive disease occurrence in their offspring.
c.- People of ethnic backgrounds in which some recessive diseases are more prevalent.
d.- Couples that will undergo Assisted Reproduction treatment, as a complement to other diagnostic tests.
e.- In Assisted Reproduction Units the test can be used for sperm/egg donors, for a better selection and risk reduction of recessive disease transmission.
