Incidence of Chronic GVHD
1 Participants

SECONDARY outcome

Timeframe: 2 Years

Population: No patients with T-cell Graft Resistant SCID were enrolled during the time the trial was open.

Based on B-cell function assays from the patient's blood, we will be able to determine if patients are able to successfully discontinue IVIG infusions.

0 Participants

SECONDARY outcome

Timeframe: 1 Year

Population: No patients with T-cell Graft Resistant SCID were enrolled during the time the trial was open.

We will measure whether we are able to detect donor stem cells in the patient's bone marrow after HSCT.
