Neurofibromatosis Type Ii

NOTE: This is a research study and is not meant to be a substitute for clinical genetic testing. Families may never receive results from the study or may receive results many years from the time they enroll. If you are interested in clinical testing please consider seeing a local genetic counselor or other genetics professional. If you have already had clinical genetic testing and meet eligibility criteria for this study as shown in the Eligibility Section, you may enroll regardless of the results of your clinical genetic testing. While it is well recognized that hereditary factors contribute to the development of a subset of human cancers, the cause for many cancers remains unknown. The application of next generation sequencing (NGS) technologies has expanded knowledge in the field of hereditary cancer predisposition. Currently, more than 100 cancer predisposing genes have been identified, and it is now estimated that approximately 10% of all cancer patients have an underlying genetic predisposition. The purpose of this protocol is to identify novel cancer predisposing genes and/or genetic variants. For this study, the investigators will establish a Data Registry linked to a Repository of biological samples. Health information, blood samples and occasionally leftover tumor samples will be collected from individuals with familial cancer. The investigators will use NGS approaches to find changes in genes that may be important in the development of familial cancer. The information gained from this study may provide new and better ways to diagnose and care for people with hereditary cancer. PRIMARY OBJECTIVE: * Establish a registry of families with clustering of cancer in which clinical data are linked to a repository of cryopreserved blood cells, germline DNA, and tumor tissues from the proband and other family members. SECONDARY OBJECTIVE: * Identify novel cancer predisposing genes and/or genetic variants in families with clustering of cancer for which the underlying genetic basis is unknown.

The goal of this clinical trial is to learn if Trineumin(Code name:PRG-N-01) works to treat Neurofibromatosis Type II(NF2) in adults. It will also learn about the safety and tolerability and toxicity of PRG-N-01. The main questions it aims to answer are: * What dose was determined as the Maximum Tolerated Dose (MTD) of Trineumin? * What dose was explored as the optimal effective dose of Trineumin based on radiographic response? * Does Trineumin reduce tumor size or improve participants' quality of life, including hearing function? * What medical problems do participants have when taking Trineumin? Participants will: * Take Trineumin every day for 96 weeks * Visit the clinic once 1, 4, 8, 12, 18week and every 12 weeks and for checkups and tests
