'He is coming to his rescue': Older brother donates stem cells to 7-year-old with rare blood disease
Pimicikamak mother Miranda McLeod has spent 4 years searching for a match for little Tanner
The mother of aboy with a rare blood disorder who hasbeen searching for a stem cell donor for the last four years says a partial match has been found her older son.
Tanner McLeod was just six months old when he was diagnosed with sideroblastic anemia.
He's unable to produce healthy red blood cellsand must have a blood transfusion every three weeks when his hemoglobin levels drop too low.
Now, thanks to scientific progress and a partial match, Tanner's brother Teemu, 17,is providing the seven-year-old with a stem cell donation.
The transplant took place on Tuesday evening in Winnipeg.
"It's really unreal, unbelievable to have someone in my own house to provide a new beginning, a new life for Tanner," said Miranda McLeod, Tanner and Teemu's mother.
For the last few years, Miranda has made it her mission to find a possible stem cell match.
Miranda is from Pimicikamak, alsoknown as Cross Lake, so Tanner was more likely to find a match within the First Nationspopulation.But donors are hard to come by.
She founded agrassroots organization Natamakewin, which meansto rescue, to save, or to help someone in Cree to both search for a match and, more broadly, to encouragepeople to join the stem cell registry through Canadian Blood Services.
She couldn't find anyone who matched her son, though.
Teemu is just a 50 per cent match, but Tanner'sdoctors said medical advancements make the transplant possible even without a perfect match.
"Tannerunderstands that his new blood cells are coming from his brother. He isvery excited and he is just so proud that his brother is willing to help him to have a healthier life," Miranda said.

She adds that Teemu is embodying the spirit of Natamakewin.
"I feel like this is what my son is receiving from his brother. Heis coming to his rescue."
She says the disorder affects Tanner's appetite, energy levelsand he turns pale when it's time for new blood.
She hopes the transplant will work and he'll be able to live a normal life.
"He loves playing sports. He Rollerblades around the house pretending to be a hockey player. He loves baseball.I hope this transplant will help him fulfil his dreams, doing what kids love to do is play without having to feel like you're feeling sick orjust have no energy," Miranda said.
But the transplant was the easy part, she says.
After that, "Tanner will wait for the new cells to settle in his body and start developing on his own. This is the part that worries me, that scares me," she said.
Miranda is asking people of different ethnic backgrounds to register with Canadian Blood Services to donate stem cells.
Because patients are more likely to find a match with a donor who shares theirancestral background, there's a particularly high needformore donors fromFirst Nations, Asian, South Asian, Hispanic, Black, and mixed-race backgrounds, a Canadian Blood Services spokesperson said.
Currently, only 33 per cent of prospective donors in the non-profit agency's stem cell registry are from thosedemographics, the spokesperson said in an email. Currently, just over one per cent of people in the registryhave First Nationsbackgrounds.
"Another serious challenge is that not all those who join the registryare still availableto donate when called," the Blood Services spokesperson said, which is why it's important for people to understand that joining the registry is a long-term commitment, and theymay get an urgent call todonate years down the road.
'A second chance'
Not everyone who needs a transplant will be as lucky as Tanner, Miranda McLeod said, and "have that fortunate experience for a second chance at a healthy life."
In November, another Manitoba family of a child with a rare immune disease wasalso calling for ethnically diverse stem cells.
Boston De Castro has hemophagocytic lymphohistiocytosis, which leads his immune system to attackitself, causing his liver and spleen to enlarge. The only cure is a stem cell transplant.
For De Castro, thebest chance of a matching donor was finding someone of mixed ethnicity like him half-Caucasian and half-Filipino, his motherSimone Janetta said.
In November,the family urged peopleespecially those of mixed ethnicity to register. A total of 3,000 peoplesigned up in Boston'sname, but unfortunately no match was found.
Instead, Janetta ended up donating her stem cells, as she was a half match.
