WFS1

Function

Participates in the regulation of cellular Ca(2+) homeostasis, at least partly, by modulating the filling state of the endoplasmic reticulum Ca(2+) store (PubMed:16989814). Negatively regulates the ER stress response and positively regulates the stability of V-ATPase subunits ATP6V1A and ATP1B1 by preventing their degradation through an unknown proteasome-independent mechanism (PubMed:23035048).

Involvement in disease

Wolfram syndrome 1

WFS1

A rare disorder characterized by juvenile-onset insulin-dependent diabetes mellitus with optic atrophy. Other manifestations include diabetes insipidus, sensorineural deafness, dementia, psychiatric illnesses.

None

The disease is caused by variants affecting the gene represented in this entry.

Deafness, autosomal dominant, 6

DFNA6

A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. DFNA6 is a low-frequency hearing loss in which frequencies of 2000 Hz and below are predominantly affected. Many patients have tinnitus, but there are otherwise no associated features such as vertigo. Because high-frequency hearing is generally preserved, patients retain excellent understanding of speech, although presbycusis or noise exposure may cause high-frequency loss later in life. DFNA6 worsens over time without progressing to profound deafness.

None

The disease is caused by variants affecting the gene represented in this entry.

Wolfram-like syndrome autosomal dominant

WFSL

A disease characterized by the clinical triad of congenital progressive hearing impairment, diabetes mellitus, and optic atrophy. The hearing impairment, which is usually diagnosed in the first decade of life, is relatively constant and alters mainly low- and middle-frequency ranges.

None

The disease is caused by variants affecting the gene represented in this entry.

Cataract 41

CTRCT41

An opacification of the crystalline lens of the eye that frequently results in visual impairment or blindness. Opacities vary in morphology, are often confined to a portion of the lens, and may be static or progressive.

None

The disease is caused by variants affecting the gene represented in this entry.

Tissue specificity

Highly expressed in heart followed by brain, placenta, lung and pancreas. Weakly expressed in liver, kidney and skeletal muscle. Also expressed in islet and beta-cell insulinoma cell line.

Cellular localization

  • Endoplasmic reticulum membrane
  • Multi-pass membrane protein
  • Cytoplasmic vesicle
  • Secretory vesicle
  • Co-localizes with ATP6V1A in the secretory granules in neuroblastoma cell lines.

Alternative names

  • Wolframin
