Summaries for Macular Dystrophy, Vitelliform, 4

OMIM® : 57 Macular dystrophies are inherited retinal dystrophies in which various forms of deposits, pigmentary changes, and atrophic lesions are observed in the macula lutea, the cone-rich region of the central retina. Vitelliform macular dystrophies (VMDs) form a subset of macular dystrophies characterized by round yellow deposits, usually at the center of the macula and containing lipofuscin, a chemically heterogeneous pigment visualized by autofluorescence imaging of the fundus (summary by Manes et al., 2013). Vitelliform macular dystrophy-4 is characterized by late-onset moderate visual impairment, small satellite drusen-like lesions in the foveal area, preservation of retinal pigment epithelium (RPE) reflectivity, deposits above the RPE between the ellipsoid and outer segment interdigitation lines on spectral-domain optical coherence tomography (SD-OCT), and normal or borderline results on electrooculography (EOG) (Meunier et al., 2014). For a discussion of genetic heterogeneity of vitelliform macular dystrophy, see VMD1 (153840). (616151) (Updated 05-Apr-2021)

MalaCards based summary : Macular Dystrophy, Vitelliform, 4, is also known as vmd4. An important gene associated with Macular Dystrophy, Vitelliform, 4 is IMPG1 (Interphotoreceptor Matrix Proteoglycan 1). Affiliated tissues include eye and retina, and related phenotypes are macular dystrophy and moderately reduced visual acuity

UniProtKB/Swiss-Prot : 72 Macular dystrophy, vitelliform, 4: A form of macular dystrophy, a retinal disease in which various forms of deposits, pigmentary changes, and atrophic lesions are observed in the macula lutea. Vitelliform macular dystrophies are characterized by yellow, lipofuscin-containing deposits, usually localized at the center of the macula. VMD4 features include late-onset moderate visual impairment, small satellite drusen-like lesions in the foveal area, and preservation of retinal pigment epithelium reflectivity.
