I doubt if it would mean that, the antithrombins were not identified until the 1950s, and the first family where this caused an issue was reported in the mid 1960s. I can remember working on the first assay to be used for antithrombin in New Zealand in the mid 1970s.

It would be most unlikely in a child of 10 months old even now that we know about it.

It is interesting that what ever it was, it was on the right thigh - very specific.
