Summaries for BFSP1 Gene

Entrez Gene Summary for BFSP1 Gene

  • This gene encodes a lens-specific intermediate filament-like protein named filensin. The encoded protein is expressed in lens fiber cells after differentiation has begun. This protein functions as a component of the beaded filament which is a cytoskeletal structure found in lens fiber cells. Mutations in this gene are the cause of autosomal recessive cortical juvenile-onset cataract. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

  • Cataract 33, multiple types (CTRCT33) [MIM:611391]: An opacification of the crystalline lens of the eye that frequently results in visual impairment or blindness. Opacities vary in morphology, are often confined to a portion of the lens, and may be static or progressive. In general, the more posteriorly located and dense an opacity, the greater the impact on visual function. CTRCT33 has juvenile-onset and the opacities are restricted to the cortex of the lens, not involving the nucleus. {ECO:0000269 PubMed:17225135, ECO:0000269 PubMed:24379646, ECO:0000269 PubMed:28450710}. Note=The disease is caused by mutations affecting the gene represented in this entry.
