Albinism is associated with a number of vision defects, such as photophobia, nystagmus, and amblyopia. Lack of skin pigmentation makes for more susceptibility to sunburn and skin cancers.

This also affects essential granules present in immune cells leading to increased susceptibility to infection. Albinism results from inheritance of recessive gene alleles and is known to affect

The purpose of the JRF is to provide accurate information to the general public about the disease and its risk factors, provide support to individuals who have thoracic aortic disease or have lost a loved one to the disease, and improve the identification of individuals at risk for aortic dissections and the treatment of thoracic aortic disease through medical research.
