Entrez Gene summary for KCNJ13 Gene:
This gene encodes a member of the inwardly rectifying potassium channel family of proteins. Members of this family
form ion channel pores that allow potassium ions to pass into a cell. The encoded protein belongs to a subfamily
of low signal channel conductance proteins that have a low dependence on potassium concentration. Mutations in
this gene are associated with snowflake vitreoretinal degeneration. Alternate splicing results in multiple
transcript variants.(provided by RefSeq, Feb 2010)

GeneCards Summary for KCNJ13 Gene:
KCNJ13 (potassium inwardly-rectifying channel, subfamily J, member 13) is a protein-coding gene. Diseases associated with KCNJ13 include kcnj13-related leber congenital amaurosis, and vitreous syneresis. GO annotations related to this gene include inward rectifier potassium channel activity.

UniProtKB/Swiss-Prot: IRK13_HUMAN, O60928
Function: Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow
into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular
potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive
voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. KCNJ13
has a very low single channel conductance, low sensitivity to block by external barium and cesium, and no
dependence of its inward rectification properties on the internal blocking particle magnesium

summary for KCNJ13 Gene:
The inward-rectifier potassium channel family (also known as 2-TM channels) include the strong
inward-rectifier channels (KIR2.x), the G-protein-activated inward-rectifier channels (KIR3.x) and the
ATP-sensitive channels (KIR6.x, which combine with sulphonylurea receptors (SUR)). Structurally, the
pore-forming subunit of KIR channels is the alpha-subunit. It contains a single pore domain between two
membrane spanning regions. Four alpha-subunits combine to form a tetramer, with the pore domain of each
subunit contributing to the structure of the central pore. Heteromeric channels can also be formed within
subfamilies, e.g. KIR3.2 with KIR3.3.

  • Snowflake vitreoretinal degeneration (SVD) [MIM:193230]: Developmental and progressive hereditary eye
    disorder that affects multiple tissues within the eye. Diagnostic features of SVD include fibrillar degeneration
    of the vitreous humor, early-onset cataract, minute crystalline deposits in the neurosensory retina, and retinal
    detachment. Note=The disease is caused by mutations affecting the gene represented in this entry
  • Leber congenital amaurosis 16 (LCA16) [MIM:614186]: A severe dystrophy of the retina, typically becoming
    evident in the first years of life. Visual function is usually poor and often accompanied by nystagmus, sluggish
    or near-absent pupillary responses, photophobia, high hyperopia and keratoconus. Note=The disease is caused by
