Gene: [01p13/ABCR] ABC transporter, retina-specific; Stargardt disease 1 (fundus flavimaculatus, autosomal recessive; MIM:248200); macular dystrophy with flecks, type 1 (MIM:248200); age-related macular degeneration 1 (ARMD1; AMD; senile macular degeneration; MIM:153800); retinitis pigmentosa 19 (autosomal recessive; MIM:601718); [STGD1 RP19 ]
|
LIN |
Martinez-Mir-1997 demonstrated linkage (maximum lod = 3.64 at theta = 0.0) with marker D1S188 located at Chr 1p21-13, the same region as Stargardt disease." |
|
MUT |
Allikmets-1997a,b showed that ABCR gene is mutated in recessive Stargardt macular dystrophy and age-related macular degeneration. Martinez-Mir-1998 showed that retinitis pigmentosa is caused by a homozygous mutation in the ABCR gene." |
|
PAT |
Martinez-Mir-1997 described a consanguineous Spanish family in which 6 of 7 sibs were affected. The parents, who were related as second cousins, were unaffected. The mean age of onset was 8 years. Night blindness was followed by a decrease in visual acuity, starting at 14 years of age. Fundus examination showed papillary pallor, attenuated vessels, peripheral scattered pigmentation, bone spicule-like pigmentation reaching some areas of the macula, and severe atrophy of the retinal pigment epithelium." |
