Age ≤ 1.0 months Appropriate organ function as outlined below must be observed within 60 days of entering this trial.~2. Hematologic~   1. Anemia (hemoglobin \< 10.5 g/dl at \< 2 years of age, or \< 11.5 g/dl at \> 2 years of age).~  2. Neutropenia (absolute granulocyte count \<500/mm3.~  3. Thrombocytopenia (platelet count \< 150,000/mm3, at any age).~  4. International Normalised Ratio (INR) or Prothrombin Time (PT) \> 2 times the upper limits of normal or Partial Thromboplastin Time (PTT) \> 2.33 times the upper limit of normal (patients with a correctable deficiency controlled on medication will not be excluded).~  5. Cytogenetic abnormalities on peripheral blood or bone marrow or amniotic fluid (if available).~  6. Prior allogeneic Hematopoietic Stem Cell Transplant (HSCT) with cytoreductive conditioning~3. Infectious~   a. Evidence of infection with HIV-1, hepatitis B, Hepatitis C, or parvovirus B 19 by DNA Polymerase Chain Reaction (PCR) within 90 days prior to bone marrow harvest. If other infection is present, it must be under control (e.g. stable or decreasing viral load) at the time of screening~4. Pulmonary~   1. Resting O2 saturation by pulse oximetry \< 95% on room air.~  2. Chest x-ray indicating active or progressive pulmonary disease.~5. Cardiac~   1. Abnormal electrocardiogram (EKG) indicating cardiac pathology.~  2. Uncorrected congenital cardiac malformation with clinical symptomatology.~  3. Active cardiac disease, including clinical evidence of congestive heart failure, cyanosis, hypotension.~  4. Poor cardiac function as evidenced by LV ejection fraction \< 40% on echocardiogram.~6. Neurologic~   1. Significant neurologic abnormality by examination.~  2. Uncontrolled seizure disorder.~7. Renal~   1. Renal insufficiency: serum creatinine \>= 1.2 mg/dl, or \>= 3+ proteinuria.~  2. Abnormal serum sodium, potassium, calcium, magnesium, phosphate at grade III or IV by Division of AIDS Toxicity Scale.~8. Hepatic/GI:~   1. Serum transaminases \> 5 times the upper limit of normal (ULN).~  2. Serum bilirubin \> 2 times ULN.~  3. Serum glucose \> 1.5 times ULN.~  4. Intractable severe diarrhea.~9. Oncologic~   1. Evidence of active malignant disease other than dermatofibrosarcoma protuberans (DFSP)~  2. Evidence of DFSP expected to require anti-neoplastic therapy within the 5 years following the infusion of genetically corrected cells~  3. Evidence of DFSP expected to be life limiting within the 5 years following the infusion of genetically corrected cells~10. Known sensitivity to Busulfan~11. General~    1. Expected survival \< 6 months.~   2. Pregnant.~   3. Major congenital anomaly.~   4. Ineligible for autologous HSCT by the criteria at the clinical site.~   5. Other conditions which in the opinion of the principal investigator and/or co-investigators, contra-indicate the bone marrow harvest, the administration of busulfan, infusion of transduced cells or indicate the patient or patient's parents/primary caregivers inability to follow protocol.
