Next-generation sequencing reveals a new mutation in the LTBP2 gene associated with microspherophakia in a Spanish family

摘要

BackgroundMicrospherophakia is a rare autosomal recessive eye disorder characterized by small spherical lens. It may present as an isolated finding or in association with other ocular and/or systemic disorders. This clinical and genetic heterogeneity requires the study of large genes (ADAMTSL4, FBN1, LTBP2, ADAMTSL-10 and ADAMTSL17). The purpose of the present study is to identify the genetic cause of this pathology in a consanguineous Spanish family.
