IMPORTANCE OF GENETICS ( AGE )TRIGGER : BETA THALASSEMIA MAJOR
General Idea
Cytogenetics in medicine. Discover the linkage of the condition of patient to the parents Prevention of other offspring with the same condition. Manifestations of the infant HBB Gene has been mutated The patient condition is conginental
CYTOGENETICS IN MEDICINE ( HOW ) ?
( 1 ) Chorionic villus sampling involves taking a small sample of the placenta for DNA testing at about 11 weeks to 14 weeks of pregnancy.
( 2 ) Amniocentesis, in which the amniotic fluid surrounding your baby is tested at between 15 weeks and 18 weeks of pregnancy.
( 3 ) Fetal blood sampling, during which a blood sample is taken from the umbilical cord between 18 weeks and 21 weeks.
Genetically the offspring has the chance of inhabiting a major thalassemia around 25% .Being a carrier of Thalassemia 50& And totally unaffected 25 %
AGE And THALASEMIA
Detected at an early stage ( MAJOR ) Conginental Defect in HBB gene was inherited mutation
