Who else in the family should be tested for Fanconi anemia (FA) depends on the inheritance pattern of the specific genetic change that is causing FA in the family. For example, FA is usually caused by genes inherited in an autosomal recessive manner (except for cases caused by FANCB). If an affected person’s FA is caused by an autosomal recessive gene, siblings of the affected person might consider testing for FA. If an affected person’s FA is caused by FANCB, the person’s mother should first be tested to see if she is a carrier for a FANCB mutation to determine the risk for other family members. Genetic counselors are available to discuss who else in your family should be tested for FA. To find genetic counselors in your area, please refer to www.nsgc.org and click "find a genetic counselor".
