About Cystinosis

Cystinosis, a genetic disease which affects approximately 2,000 individuals worldwide, is a rare, life-threatening condition in which the body accumulates the amino acid cystine (a building block of proteins) within cells. Excess cystine leads to formation of crystals that can build up and damage cells throughout the body. Cystinosis slowly destroys numerous vital organs including the kidneys, liver, eyes, muscles and the brain. Other complications of cystinosis include muscle weakness, diabetes, hypothyroidism, difficulty in swallowing and rickets. Corneal cystine accumulation can lead to ocular complications such as squinting, foreign body sensations, changes in visual acuity, corneal haziness and photophobia (i.e., sensitivity to light). The clinical safety and efficacy of CYSTARAN has been evaluated in controlled clinical trials conducted by the NIH in approximately 300 patients.

Jack Kitchens

My name is Jack Kitchens and I am the 2018 recipient of the CRN academic scholarship. I am honored to receive this reward and will make sure to put it to good use. I will use this scholarship to pay for my college books and help further my education. My final goal is to get a degree in Biology and work in a lab. Cystinosis has been a huge part of my life since I was diagnosed at 13 months old. Since then, my family members and many others have done all they can to help me live with cystinosis, and I am extremely thankful for that. The cystinosis community means a lot to me and I hope it continues to help people living with cystinosis. Thank you guys so much for the support, I am forever grateful for it.

Kathleen Roberts

One thing that anyone with cystinosis can say is they have been exposed to many, many aspects of health care. Consequently, my health and medical experiences have sparked an intense passion for supporting others. Growing up around nurses, doctors, dieticians, social workers, pharmacists, and technicians has given me insight into many corners of the medical field. However, what has stuck with me the most is the value of the profession of nursing. My relationships with nurses, both on the ward and in outpatient clinics, has had a significant influence on my life outlook. Many of them have become amazing role models for me. My nurses have shown me how a good medical team, and especially a good nurse, can make an enormous, positive difference to someone’s medical story. Because of the care and support I have received from many nurses, it has been my dream and goal in life to provide the same excellent standard of supportive health care to others that I have personally received.

I was fortunate enough to be accepted into the University of British Columbia’s Bachelor of Science in Nursing program and I am extremely grateful for the CRN scholarship which will help finance my education. As I am living on campus and away from home my education expenses are high. This scholarship means so much to me as it is helping me to achieve my career goals and dreams. I am very appreciative.

Emily Ann Bogan

It is an honor to receive the 2018 Sierra Woodward Academic Scholarship. I am currently attending Central Carolina Community College in Sanford, NC, where I am studying Criminal Justice. Receiving this scholarship will help me achieve my goal of receiving an Associate Degree in Criminal Justice Technology. Following completion at CCCC, it is my dream to find employment in the Criminal Justice field working with addiction and/or at-risk youth. I greatly appreciate the CRN’s recognition and support as I pursue my academic endeavors.

Rhyana Juutilainen

When my first sister was diagnosed with cystinosis in December 2011, I thought my whole world was ending. It was like this diagnosis was this huge brick wall between myself and this idea of the future that I had at the time. However, as the years went by, I started to realize a few things. The first was that cystinosis is sort of like giant brick wall; it’s so big and complicated that it’s hard to explain others who do not face this wall, but that doesn’t mean you are the only one behind the wall and trying to get over or through the wall. I also realized that cystinosis does not stop you from reaching the future that you want. Throughout middle school and high school, I was simply given metaphorical rungs on a latter to help me see past cystinosis. I saw that just because cystinosis puts a strain on my family, that shouldn’t stop me from achieving a future that I want. This scholarship will help get through my first year at the University of Nebraska at Omaha, majoring in Criminology. My hope is one day to work in the FBI or CIA as a Criminologist. Thanks to this scholarship, I am one rung closer to achieving a future that I would not have imagined when my sister was first diagnosed.
