A two-year-old York County boy is in need of a bone marrow transplant.

Joey Duffy was recently diagnosed with myelodysplastic syndrome, or MDS, a rare blood and bone marrow disorder.

"In September he went in for a hematology appointment and he was diagnosed with MDS. We found out he was going to need a bone marrow transplant," said Tom Duffy, Joey's father.

"We found out that if he does not have a bone marrow transplant sooner rather than later, it can evolve into Leukemia. So we're very lucky we caught it as early as we did," said Joey's mother, Maura Duffy.

The Duffys are having a donor drive at their church, Saint Andrew's Episcopal on Sunday. People who show up will be tested to see if they're a match for Joey.

"They swab the inside of your cheek and when they swab the inside of the cheek, they can find out what type you are," Tom said.

 Joey's immediate family members have the best chance of being a match for him. His parents and two older brothers have already done the cheek swap and are now waiting to find out if any of them will be a match.

Although the Duffys' number one priority this weekend is finding a match for Joey, his father says they're also working to raise awareness about MDS and possibly help someone else who needs a transplant.

 "If we could help save somebody else's child or someone else going through this, that would be great. And that's one of the goals, to find somebody else a match as well," he said.
