Abstract

BACKGROUND: Age-related macular degeneration (AMD) is the most common cause of irreversible vision loss in the developed world. The study of a rare mendelian form of macular degeneration implicated fibulin genes in the pathogenesis of more common forms of this disease. We evaluated five fibulin genes in a large series of patients with AMD. METHODS: We studied 402 patients with AMD and 429 control subjects from the same clinic population. Patients were examined by means of indirect ophthalmoscopy, slit-lamp microscopy, and fundus photography to establish the presence and phenotypic pattern of AMD. DNA samples were screened for sequence variations in five members of the fibulin gene family. RESULTS: Amino acid-altering sequence variations were found in all five fibulin genes, many of which were observed only in patients with AMD. Several of the altered residues have been conserved during evolution. Seven of the 402 patients with AMD had amino acid-altering sequence variations in the fibulin 5 gene, whereas none were observed among 429 control subjects (P<0.01). In addition, these seven patients all had small, circular drusen, which are commonly referred to as basal laminar or cuticular drusen. CONCLUSIONS: Missense mutations in the fibulin 5 gene were found in 1.7 percent of patients with AMD. Many variations in other fibulin genes were also found in these patients, and the evolutionary conservation of the affected residues suggests that several of these variations may also be involved in AMD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
