Disorders for TMEM126A Gene

(1) OMIM Diseases for TMEM126A Gene (612988)


  • Optic atrophy 7 with or without auditory neuropathy (OPA7) [MIM:612989]: A hereditary condition that features progressive visual loss in association with optic atrophy. Atrophy of the optic disk indicates a deficiency in the number of nerve fibers which arise in the retina and converge to form the optic disk, optic nerve, optic chiasm and optic tracts. OPA7 is an autosomal recessive juvenile-onset optic atrophy characterized by severe bilateral deficiency in visual acuity, optic disk pallor, and central scotoma. Some patients manifest hearing loss. {ECO:0000269 PubMed:19327736}. Note=The disease is caused by mutations affecting the gene represented in this entry.
