A FBN1 variant manifesting as non-syndromic ectopia lentis with retinal detachment: clinical and genetic characteristics

BACKGROUND/OBJECTIVES: Fibrillin-1 (FBN1) mutations cause connective tissue dysgenesis the main ocular manifestation being ectopia lentis (EL), which may be syndromic or non-syndromic. We describe a pedigree with a FBN1 mutation causing non-syndromic EL with retinal detachment (RRD) and their manage...

Sumario:BACKGROUND/OBJECTIVES: Fibrillin-1 (FBN1) mutations cause connective tissue dysgenesis the main ocular manifestation being ectopia lentis (EL), which may be syndromic or non-syndromic. We describe a pedigree with a FBN1 mutation causing non-syndromic EL with retinal detachment (RRD) and their management. SUBJECTS/METHODS: Patients with familial EL with RRD were invited to participate (vitreoretinopathy branch of Target 5000, the Irish inherited retinal degeneration study). All patients signed full informed consent. The study was approved by the Institutional Review Board of the Mater Hospital, Dublin and abided by the Declaration of Helsinki. RESULTS: Seven adults were affected with bilateral EL. All subjects had RRD with bilateral non-synchronous RRD in 57%. CONCLUSIONS: The FBN1 variant described herein confers an increased risk of both EL and RRD and can now be upgraded to ‘pathogenic’ ACMG status.
