Usher syndrome (sometimes referred to as "Usher's syndrome") is a relatively rare genetic disorder that is associated with a mutation in any one of 10 genes resulting in a combination of hearing loss and visual impairment and is a leading cause of deafblindness. Other names for Usher syndrome include Hallgren syndrome, Usher-Hallgren syndrome, retinitis pigmentosa-dysacusis syndrome and dystrophia retinae dysacusis syndrome. Usher syndrome is incurable at present; however, using gene therapy to replace the missing gene, researchers have succeeded in reversing one form of the disease in knockout mice.

Famous quotes containing the words usher and/or syndrome:
“As long as skies are blue, and fields are green
Evening must usher night, night urge the morrow,
Month follow month with woe, and year wake year to sorrow”
—Percy Bysshe Shelley (1792–1822)
“Women are taught that their main goal in life is to serve others—first men, and later, children. This prescription leads to enormous problems, for it is supposed to be carried out as if women did not have needs of their own, as if one could serve others without simultaneously attending to one’s own interests and desires. Carried to its “perfection,” it produces the martyr syndrome or the smothering wife and mother.”
—Jean Baker Miller (20th century)
