<unk>  can be caused by both genetic and environmental factors, such as a viral infection (like measles). Ribonucleic acid of the measles virus has been found in stapes footplate in most patients with<unk> . Populations that have been vaccinated against measles had a significant reduction in<unk> . While the disease is considered to be hereditary, its penetrance and the degree of expression is so highly variable that it may be difficult to detect an inheritance pattern. Most of the implicated genes are transmitted in an autosomal dominant fashion. One genome-wide analysis associates<unk>  with variation in RELN gene.
