Why ViaCord Sibling Connection. What is the Sibling Connection Program? Based on the way parents pass on genes, there is a 25 percent chance that two siblings will be a whole match, a 50 percent chance they will be a half match and a 25 percent chance that they will not be a match at all.

It is very rare for a parent to be a match with their own child, and even more rare for a grandparent to be a match. You certainly should, especially if you have a family history of any conditions that could be treated with cord blood stem cells. As there is no guarantee of a suitable match, we recommend banking the cord blood of each individual child. We understand that can be a costly proposition, which is one of the reasons we offer competitively priced and flexible payment options.

If a sibling of a child whose cord blood you banked needs a transplant, then your chances of a match will be far higher than turning to the public. However, the safest bet is to bank the cord blood of all your children, safeguarding them against a number of conditions and doing your best to ensure a genetic match if necessary.

Preserving stem cells does not guarantee that the saved stem cells will be applicable for every situation. Cord blood remains a desirable method for which to treat such patients, so it becomes even more imperative that families have access to a pool of autologous and related-allogenic specimens.

Through research, it has also been discovered that some neurodegenerative conditions are best managed with multiple infusions , as one such study found in the case of congenital hydrocephalus. One challenge of cord blood use is the volume of umbilical cord blood is relatively small. Due to low cell content, cord blood transplants have generally been limited to patients who are low-weight or children. However, approaches to overcoming this challenge have been managed with success, which involves co-infusion of two partially HLA-matched specimens.

According to data from the Eurocord Registry, it is reported that, since , the number of adult patients undergoing double umbilical cord transplantation has surpassed the number of adults with single cord blood units.

Clinical studies show that haploidentical, or half-matched sibling transplantations are successful, and graft versus host disease is less common than in matched, unrelated bone marrow transplantations.

Banking for each child provides each child with the option to use their own cord blood autologous. The second highest chance of a genetic match comes from siblings, and especially those with a family history of conditions that can be treated through umbilical stem cells. The better the match—a six-of-of-six match is better than a four-out-of-six match—the better the outcome and the more likely any GvHD symptoms will be mild, if they suffer from GvHD at all.

In this simplified example of how HLA can be inherited, we can see the baby is match for one sibling and a half match for each parent. Each parent bestows one HLA group haplotype to their baby, so half the HLA markers come from the mother and half from the father.

Half-siblings only share the HLA markers from one parent, and even then, they may not have received the same markers from that one parent. Outside the small chance the dad and step dad or mom and step mom are compatible on some level, half-siblings can only be up to a half-match.

Blood-related aunts and uncles and grandparents may have some compatibility, but it may be insufficient for transplantations especially as genetic recombination becomes a major factor in which genes are inherited. My Account Get Started. Toggle navigation.
