مستخلص: | Introduction: We report a case of pseudoxanthoma elasticum (PXE) with an atypical phenotype likely related to a hypomorphic variant in ABCC6 . Case Presentation: A 66-year-old Caucasian female with a history of a maculopathy interpreted as either age-related macular degeneration or a pattern dystrophy underwent a detailed ophthalmic evaluation. Visual acuities were 20/25, OD, and 20/20, OS. Spectral domain optical coherence and fluorescein angiography demonstrated outer retinal disruptions and breaks in retinal pigment epithelium (RPE)/Bruch's membrane bilaterally, consistent with angioid streaks. A large area of hypo- and hyperautofluorescence extending from the central retina into the peripapillary retina was documented with short-wavelength excitation autofluorescence. The area of hypoautofluorescence, which was much larger on near-infrared excitation, spared the temporal retina. Two-color dark-adapted perimetries documented severe rod sensitivity losses and less severe cone sensitivity abnormalities co-localizing with the RPE abnormalities. No obvious skin findings were observed, and initial dermatologic biopsy was negative. Gene screening identified a pathogenic ABCC6 gene variant c.1552C>T and a previously reported variant of uncertain significance c.1171A>G. A second dermatologic biopsy demonstrated positive findings consistent with PXE. Conclusion: Although this patient had minimal skin findings, this patient had characteristic structural and functional abnormalities of a pattern dystrophy with angioid streaks and histologic evidence of PXE, suggesting compound heterozygous variants involving the hypomorphic ABCC6 c.1171A>G variant. These findings support the pathogenic role of both variants. Competing Interests: The authors have no financial disclosures. (© 2024 The Author(s). Published by S. Karger AG, Basel.) |
