Photoreceptor cells are susceptible to cellular stress - their degeneration and loss is a major cause of blindness. Many genes have identified for the inherited and highly heterogeneous disorders resulting from photoreceptor degeneration. One of the most common form is retinitis pigmentosa (RP) and its patterns of inheritance are varied - some are autosomal dominant (adRP), others are autosomal recessive (arRP), a smaller fraction are X-linked (XLRP) and between 30 to 50% have not yet been class
