Entrez Gene Summary for LTBP2 Gene

  • The protein encoded by this gene belongs to the family of latent transforming growth factor (TGF)-beta binding proteins (LTBP), which are extracellular matrix proteins with multi-domain structure. This protein is the largest member of the LTBP family possessing unique regions and with most similarity to the fibrillins. It has thus been suggested that it may have multiple functions: as a member of the TGF-beta latent complex, as a structural component of microfibrils, and a role in cell adhesion.

GeneCards Summary for LTBP2 Gene

LTBP2 (Latent Transforming Growth Factor Beta Binding Protein 2) is a Protein Coding gene. Diseases associated with LTBP2 include glaucoma 3, primary congenital, d and microspherophakia and/or megalocornea, with ectopia lentis and with or without secondary glaucoma. Among its related pathways are NF-KappaB Family Pathway and NF-KappaB Family Pathway. GO annotations related to this gene include calcium ion binding and growth factor binding. An important paralog of this gene is LTBP3.

Disorders for LTBP2 Gene

(3) OMIM Diseases for LTBP2 Gene (602091)


  • Glaucoma 3, primary congenital, D (GLC3D) [MIM:613086]: An autosomal recessive form of primary congenital glaucoma (PCG). PCG is characterized by marked increase of intraocular pressure at birth or early childhood, large ocular globes (buphthalmos) and corneal edema. It results from developmental defects of the trabecular meshwork and anterior chamber angle of the eye that prevent adequate drainage of aqueous humor. {ECO:0000269 PubMed:19361779}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Microspherophakia and/or megalocornea, with ectopia lentis and with or without secondary glaucoma (MSPKA) [MIM:251750]: A rare disease characterized by smaller and more spherical lenses than normal bilaterally, an increased anteroposterior thickness of the lens, and highly myopic eyes. Lens dislocation or subluxation may occur, leading to defective accommodation. {ECO:0000269 PubMed:20617341}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Weill-Marchesani syndrome 3 (WMS3) [MIM:614819]: A rare connective tissue disorder characterized by short stature, brachydactyly, joint stiffness, and eye abnormalities including microspherophakia, ectopia lentis, severe myopia and glaucoma. {ECO:0000269 PubMed:22539340}. Note=The disease is caused by mutations affecting the gene represented in this entry.
