Case 3 is a 6yo male. VA: OD: 20/150, OS: 20/200. Proband had macular atrophy and flecks at the posterior pole. In the autofluorescence exam, there was peripapillary sparing of the hyper-autofluorescent flecks. On OCT images the atrophic areas at the macula correlated to disruption of the elipsoid layer and decrease in the foveal thickness. OCT showed loss of the photoreceptor layer and EPR layer. Proband has only 1 ABCA4 variant, so not eligible for PP4. Also has a variant in PROM1 (p.Ala643Gly). ABCA4, PROM1, and ELOVL4 genes sequenced by next-generation sequencing (NGS) test.

GenotypingMethod: Thirty-two of the most common disease-causing ABCA4 variations were selected for the initial screen. The entire research cohort was assayed for these 32 variations using a combination of SNPlex, SSCP analysis, TaqMan and automated DNA sequencing. All CRD and RP patients who had one plausible disease-causing allele identified in the first tier of screening were assayed by automated sequencing of the entire coding region of the ABCA4 gene in an effort to identify their second disease-causing allele. In addition, Stargardt patients who had one of the three most common alleles (Gly863Ala, Gly1961Glu or IVS38-10) were also sequenced through the entire coding region of the ABCA4 gene.
