last update : 16-11-2021
Symbol STGD3
Location 6q14
HGNC id 11383
Name Stargardt disease 3
Other name(s) macular dystrophy with flecks, type 3
Corresponding gene ELOVL4
related resource Retinal Information Network
Other symbol(s) STGT3, ADMD
Main clinical features
  • early onset by photophobia
  • characterized by decreased central vision, atrophy of the macula and underlying retinal-pigment epithelium and frequent yellow "flavimaculatus flecks" in the posterior pole of the retina (includes rhe formely STGD2)
  • Genetic determination autosomal dominant
    Function/system disorder eye
    Type disease
    Mechanism(s)
    Gene mutationChromosome rearrangementEffectComments
    unknown     mutant not localizing to the ER but rather appears to be sequestered elsewhere in an aggregated pattern in the cytoplasm
    Remark(s)
  • C-terminal truncation mutants exert a dominant negative effect on wild type , altering its subcellular localization
  • inactivation of the wild-type ELOVL4 protein through sequestration to a non-ER compartment by ELOVL4 mutants may play a role in cellular dysfunction
  • mutant ELOVL4 interacts with the wild-type protein, forming higher molecular mass complexes that accumulate in aggresomes
