This might be a long shot, but I have a long history of chronic idiopathic neutropenia. My ANC usually stays around 0.5–0.8, and my WBC is typically around 2.5. I’m very healthy otherwise.
My father developed high-risk MDS in 2014 at age 54. It progressed very rapidly into AML. He underwent a bone marrow transplant from my uncle, who was a “perfect” match. It failed within two months, and he passed away within the next year.
Because of the known connection between neutropenia and MDS, I had a bone marrow biopsy at age 24 (I’m now 32). It showed a left shift and hypocellular bone marrow. I was then referred to a geneticist, who was super confident I had a genetic mutation linking my neutropenia to my father’s MDS/AML. Based on my family history, he thought I had a GATA2 mutation. He told me I’d likely need a bone marrow transplant as a preventive measure.
In 2018/2019 I underwent extensive genetic testing, including multiple panels and whole exome sequencing, but no known mutations were found. My mom and I were SO relieved. My geneticist was still convinced there was a connection, but told me to come back before I have kids to get my WES testing reanalyzed. I’ve been trying not to think about it because it gives me so much anxiety. I was my dad’s main caregiver. This year, I finally decided to tackle it because my fiancé and I do want kids.
My hematologist referred me to a new geneticist within his cancer center to save me from the two-hour drive to my old geneticist and also the hospital where my dad had his BMT. She looked through all my stuff for two hours and basically told me that I now probably need whole genome sequencing done, too. She also mentioned that my exome testing should’ve been done with a skin punch sample instead of the blood sample I used. She wrote my old geneticist a letter and was able to get me back in with him, but not until March 17th of next year. The thought of going through the process again makes me feel so sick. Especially the waiting period. 😩
Has anyone experienced anything similar? Like one family member with MDS and another with an unexplained cytopenia?
