WFS1

Wolframin is a protein that in humans is encoded by the WFS1 gene.

Function

Wolframin is a transmembrane protein. Wolframin appears to function as a cation-selective ion channel.

Clinical significance

Mutations in this gene are associated with an autosomal recessive syndrome characterized by insulin-dependent diabetes mellitus and bilateral progressive optic atrophy, usually presenting in childhood or early adult life. Diverse neurologic symptoms, including a predisposition to psychiatric illness, may also be associated with this disorder. A large number and variety of mutations in this gene, particularly in exon 8, can be associated with this syndrome. Mutations in this gene can also cause autosomal dominant deafness 6 (DFNA6), also known as DFNA14 or DFNA38.

Mutations in this gene have also been associated with congenital cataracts.

    A Passed Life

    by: FOZZY

    Mystery finds me in darkness
    Sun won't shine
    Blistering pain from a passed life
    Cross that line
    (CHORUS)
    Into the moonlight I ride
    One-way trip, to the other side
    Into the moonlight I ride
    Losing my grip, I cannot hide
    Standing on top of a mountain
    Long way down
    Hearing the voice of a madman
    Hit the ground
    (CHORUS)
    Into the moonlight I ride
    One-way trip to the other side
    Into the moonlight I ride
    Losing my grip, I cannot hide
    Into the casket I go
    Debt has been paid seeds have been sown
    End of the line all that I know
    Into Inferno I crawl
    Licking the flames, tasting my fall
    Melting away sirens that call
    (CHORUS)
    Into the moonlight I ride
    One-way trip to the other side
    Into the moonlight I ride
    Losing my grip, I cannot hide
    Dreaming about my passed life
    Into the moonlight I ride
    One-way trip to the other side
    Into the moonlight I ride
    Losing my grip, I cannot hide
    Oh I can't hide
    From my passed life
    Oh I can't hide
