Brief summary: This phase II Pediatric MATCH trial studies how well tazemetostat works in treating patients with brain tumors, solid tumors, non-Hodgkin lymphoma, or histiocytic disorders that have come back (relapsed) or do not respond to treatment (refractory) and have EZH2, SMARCB1, or SMARCA4 gene mutations. Tazemetostat may stop the growth of tumor cells by blocking EZH2 and its relation to some of the pathways needed for cell proliferation.

Detailed description: PRIMARY OBJECTIVE:

I. To determine the objective response rate (ORR; complete response + partial response) in pediatric patients treated with tazemetostat with advanced solid tumors (including central nervous system \[CNS\] tumors), non-Hodgkin lymphoma or histiocytic disorders that harbor gain of function mutations in EZH2, or loss of function mutations in the SWI/SNF complex subunits SMARCB1 or SMARCA4 at a dose of 520 mg/m\^2/dose twice daily for patients without any CNS involvement or 1200 mg/m\^2/dose orally twice daily for patients with CNS involvement.

SECONDARY OBJECTIVES:

I. To estimate the progression-free survival in pediatric patients treated with tazemetostat that harbor gain of function mutations in EZH2, or loss of function mutations in the SWI/SNF complex subunits SMARCB1 or SMARCA4.

II. To obtain information about the tolerability of tazemetostat in children with relapsed or refractory cancer.

EXPLORATORY OBJECTIVES:

I. To evaluate other biomarkers as predictors of response to tazemetostat and specifically, whether tumors that harbor different missense mutations or fusions will demonstrate differential response to tazemetostat treatment.

II. To explore approaches to profiling changes in tumor genomics over time through evaluation of circulating tumor deoxyribonucleic acid (DNA).

OUTLINE:

Patients receive tazemetostat orally (PO) twice daily (BID) on days 1-28. Cycles repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.

Eligibility criteria: Inclusion Criteria:

* Patient must have enrolled onto APEC1621SC and must have been given a treatment assignment to Molecular Analysis for Therapy Choice (MATCH) to APEC1621C based on the presence of an actionable mutation
* Patients must have radiographically measurable disease at the time of study enrollment; patients with neuroblastoma who do not have measurable disease but have MIBG+ evaluable disease are eligible; measurable disease in patients with CNS involvement is defined as tumor that is measurable in two perpendicular diameters on magnetic resonance imaging (MRI) and visible on more than one slice; Note: The following do not qualify as measurable disease:

  * Malignant fluid collections (e.g., ascites, pleural effusions)
  * Bone marrow infiltration except that detected by MIBG scan for neuroblastoma

    * Autologous stem cell infusion including boost infusion: \>= 42 days
  * Cellular therapy: \>= 42 days after the completion of any type of cellular therapy (e.g. modified T cells, natural killer \[NK\] cells, dendritic cells, etc.)
  * Radiation therapy (XRT)/external beam irradiation including protons: \>= 14 days after local XRT; \>= 150 days after TBI, craniospinal XRT or if radiation to \>= 50% of the pelvis; \>= 42 days if other substantial bone marrow (BM) radiation; Note: Radiation may not be delivered to "measurable disease" tumor site(s) being used to follow response to subprotocol treatment

* Patients with known bone marrow metastatic disease will be eligible for study provided they meet the blood counts (may receive transfusions provided they are not known to be refractory to red cell or platelet transfusions); these patients will not be evaluable for hematologic toxicity
