Growth impairment, vision problems and chronic kidney ailment are hallmarks of cystinosis, a rare genetic disease that affects children, who, in most cases, do not survive into their adulthood. The disease affects one in about 250000 children worldwide and many of them go undiagnosed in the initial stages, only to be detected at a later stage when complications develop in the kidneys. Now, a new study by researchers and doctors at the Indian Institute of Science and Education Research (IISER), Mohali, and the Madras Institute of Orthopaedics and Traumatology (MIOT), Chennai, may have clues to detecting this disease early on in Indian patients, thus opening up possibilities of early diagnosis and treatment.
