3 Genetic tests for cancer gene

Dez was diagnosed with AML Leukemia back in Oct of 2018.  She has been fighting this since.  We have finally got some answers for why her platelets are not producing as much and its Bone Marrow Failure.  We are in the process of getting Desiree a bone marrow transplant but before we can move forward with this transplant we need to find out if her brother junior is her match.  We need to do genetic testing on him as well as her two younger brothers.  The gene runx1 was detected in her dad (Chente) and in her gene.  We are at a 50/50 chance of each sibling having this gene which causes the AML Leukemia.  Her brother junior does not have insurance as we just moved him back to the states and the medical insurance we have for the boys doesn't cover the tests either.  Any and all help is appreciated.  From the bottom of our hearts we thank you.  #dezstrong
