Science Médicale - Tests Génétiques et Prénataux

a genetic test that identifies mutations in the BRCA1 and BRCA2 genes, which are associated with an increased risk of breast and ovarian cancers

a gene associated with increased risk of breast and ovarian cancers due to mutations, making it important in cancer genetics and testing

a gene linked to increased risk of breast and ovarian cancers due to mutations, important in cancer genetics and testing

genetic testing to identify individuals who carry gene mutations for certain conditions, informing reproductive decision-making

a laboratory test that examines an individual's chromosomes to detect genetic abnormalities such as chromosomal disorders and syndromes

a gene associated with increased risk of health conditions such as cardiovascular disease, neural tube defects, and psychiatric disorders due to specific mutations

(genetics) a basic unit of heredity and a sequence of nucleotides in DNA that is located on a chromosome in a cell and controls a particular quality

gène

(biochemistry) a chemical substance that carries the genetic information, which is present in every cell and some viruses

ADN

a very small threadlike structure in a living organism that carries the genes and genetic information

chromosome

a genetic change that can affect chromosome structure or number, leading to variations in gene expression and potential genetic disorders

a genetic test that identifies mutations in the MTHFR gene to assess an individual's risk for health conditions

a type of genetic testing that analyzes an individual's genetic makeup to assess how their genes may impact their response to certain medications

a tumor suppressor gene associated with increased cancer risk due to mutations, important in cancer genetics and testing

a genetic test identifies mutations in the PTEN gene to assess an individual's risk for associated conditions such as cancers and other health conditions

a tumor suppressor gene associated with increased cancer risk due to mutations, important in cancer genetics and testing

a genetic test that identifies mutations in the TP53 gene to assess an individual's risk for associated conditions such as cancers and other health conditions

a complex biological structure essential for cellular functions in living organisms, made up of amino acid chains

a visual display of an individual's chromosomes, used for genetic analysis and identifying abnormalities

genetic testing on embryos during IVF to screen for genetic conditions or abnormalities prior to implantation

a test to check the baby's health by taking a small amount of fluid from around the baby before birth

amniocentèse

a test done during pregnancy that involves taking a small sample of tissue from the developing pregnancy to check for genetic issues in the baby

a specialized ultrasound examination that assesses the heart of a developing fetus in utero for any potential structural or functional abnormalities

a medical imaging technique used to visualize the developing fetus, assess fetal growth, identify abnormalities, and evaluate maternal reproductive organs during pregnancy

a prenatal blood test that assesses the risk of chromosomal disorders in the fetus by measuring four markers in the mother's blood

a non-invasive prenatal test that analyzes fetal DNA in the mother's blood to screen for chromosomal abnormalities with high accuracy

a medical test that uses sound waves to create pictures of a growing baby inside a pregnant woman's uterus to check for any potential problems

a prenatal procedure that involves withdrawing a small sample of fetal blood from the umbilical cord for diagnostic purposes

a prenatal test that measures fetal neck thickness to assess chromosomal abnormalities during early pregnancy

a medical image taken using sound waves, commonly used in pregnancy to monitor fetal development

a medical imaging method using sound waves for real-time visual examinations of the body's internal structures
