Patients with new or progressive brain metastases (active brain metastases) or leptomeningeal disease are eligible if the treating physician determines that immediate CNS specific treatment is not required and is unlikely to be required for at least 4 weeks (or scheduled assessment after the first cycle of treatment), and a risk-benefit analysis (discussion) by the patient and the investigator favors participation in the clinical trial
• The effects of nivolumab on the developing human fetus are unknown. For this reason, women of child-bearing potential (WOCBP) and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. WOCBP receiving nivolumab will be instructed to adhere to contraception for a period of 5 months after the last dose of investigational product. Men receiving nivolumab and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 7 months after the last dose of investigational product. Women of childbearing potential must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [HCG]) within 24 hours prior to the start of nivolumab. Women must not be breastfeeding. Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile as well as azoospermic men) do not require contraception. WOCBP is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) or who is not postmenopausal. Menopause is defined clinically as 12 months of amenorrhea in a woman over 45 in the absence of other biological or physiological causes. In addition, women under the age of 55 must have a documented serum follicle stimulating hormone (FSH) level less than 40 mIU/mL. These durations have been calculated using the upper limit of the half-life for nivolumab (25 days) and are based on the protocol requirement that WOCBP use contraception for 5 half-lives plus 30 days, and men who are sexually active with WOCBP use contraception for 5 half-lives plus 90 days. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she (or the participating partner) should inform the treating physician immediately

Further Characterization of Oxidase Level, Longitudinal Study, Prospective Cohort Patients who are to undergo transplantation during the study period must be further characterized as oxidase-null or oxidase positive by level of oxidase production by either:
• DHR assay stimulation Index: where SI ≤ 2.5 will be classified as oxidase-null CGD. Those with SI > 2.5 will be classified as oxidase positive CGD. A single validated test that is accepted by the PID-CGD Review Panel is adequate, but testing on two occasions for validation is desirable. OR

• *Hypomorphic mutation in a SCID causing gene
• Low TRECS and/or the percentage of CD4+/45RA+/CD31+ or CD4+/45RA+/CD62L+ cells is below the lower limit of normal. Reticular Dysgenesis:

• c.) A pathogenic mutation in the adenylate kinase 2 (AK2) gene identified. Stratum C: Subjects who meet the following criteria and the intention is to treat with therapy other than allogeneic HCT, primarily PEG-ADA ERT or gene therapy with autologous modified (gene transduced) cells, are eligible for enrollment into Stratum C:
• ADA Deficient SCID with intention to treat with PEG-ADA ERT
• ADA Deficient SCID with intention to treat with gene therapy
• X-linked SCID with intention to treat with gene therapy
• Any SCID patient previously treated with a thymus transplant (includes intention to treat with HCT, as well as PEG-ADA ERT or gene therapy)
• Any SCID patient who received therapy for SCID deemed "non-standard" or "investigational", including in utero procedures. -Subjects who meet any of the following exclusion criteria are disqualified from enrollment in Strata A, B, or C of the study:
• Presence of an Human Immunodeficiency Virus (HIV) infection (by PCR) or other cause of secondary immunodeficiency
• Presence of DiGeorge syndrome
• MHC Class I and MHC Class II antigen deficiency, and
• Metabolic conditions that imitate SCID or related disorders such as folate transporter deficiency, severe zinc deficiency or transcobalamin deficiency.

1. Patient must have a clinical diagnosis of morphea confirmed by the primary investigator and by histopathological examination. 2. Ages 0-90 years old 3. Children must weigh more than 20 lbs. in order to satisfy Children's Medical Center policy for the maximum amount of blood drawn in a 24 hour period. 4. Patient or legal guardian must be able to speak and read at a 6th grade reading level. 5. Both male and female patients will be eligible 6. All races and ethnic backgrounds will be included 7. Relationships to proband: All patients with morphea will be included. A patient's family history will be reviewed and if there is a family history of morphea or systemic sclerosis then we will give the study patient the investigator's contact information and ask the family member to call the study team to answer any questions and enroll them in the study if they choose to do so. 8. Ability to give informed consent: Patients must be able to give informed consent or they will give assent with parent or guardian consent as a minor to be a part of the morphea registry.
•Patients who have been coded as morphea (701.0), but do not have morphea/localized scleroderma (examples: steroid atrophy, acquired keratoderma, keloids, nephrogenic fibrosing dermopathy, systemic sclerosis, lichen sclerosis)

• Completion of a qualifying Ra Pharmaceuticals sponsored zilucoplan study
• With the exception of a prior zilucoplan trial, participation in another concurrent clinical trial involving an experimental therapeutic intervention (participation in observational studies and/or registry studies is permitted)
