In brief: Accounts for 1% DS
Mosaicism is encountered in ds patients & I have followed one in the past.
By definition, some tissues are composed of cells with normal information & other tissues have the abnormal, but the mix could vary greatly in the percentage of either. Functional outcome depends on that blend & whether the abnormally derived tissues compose critical structures like brain, blood, reproductive organs, etc.
