If a child is diagnosed as Fanconi anemia, can his brothers and sisters also be affected?
Fanconi anemia is an inherited anemia. Both parents must be carriers of the Fanconi anemia gene for their child to be born with this disorder. If both parents carry the gene the chances are one in four (25%) that other children will also inherit the disease. This pattern of inheritance is known as “autosomal recessive” in medical terminology. Thus, once a child is diagnosed as Fanconi anemia, other siblings in the family should also undergo the chromosomal breakage test even though they are normal otherwise. Fanconi anemia can also be diagnosed before a child is born. The diagnosis can be done by performing a procedure called as chorionic villus sampling (CVS) at 10th – 12th week of pregnancy or by amniocentesis at 15th to 17th week of pregnancy and testing for chromosomal breakage.
