The Cri du Chat Research Foundation is a 501c3 Non-Profit Organization, based in New York City, that is spearheading efforts to raise funding to support and facilitate biomedical research specifically for Cri Du Chat Syndrome, also known as 5p Minus. Cri Du Chat Syndrome is an extraordinarily rare chromosomal disorder that affects approximately 1 in 50,000 newborns annually. It occurs when there is a deletion of genetic material at the top portion of the 5th chromosome, resulting in a wide spectrum of intellectual and developmental challenges, and in certain cases catastrophic medical complications. Our Organizational purpose is to help establish a biobank and genetic registry, specific to Cri du Chat Syndrome, that will give access and opportunities for Scientists and Researchers to study, explore the pathophysiology of the syndrome as well as to try experimental therapies with enabling direct use of genetic specimens from one centralized location. Our mission is to have these endeavors encourage further studies that lead to translational research, and ultimately improvement in the quality of life for those dealing with these lifetime of challenges. **Cri Du Chat Research Foundation is a tax-exempt organization as described in Section 501(c)(3) of the Internal Revenue Code; EIN 47-1749667**
