BRIEF DESCRIPTION

SNRNP200 retinitis pigmentosa (RP) is a type of autosomal dominant retinitis pigmentosa (adRP) caused by mutations in the SNRNP200 gene. SNRNP200 is a gene that encodes a protein called hBrr2, which is a component of the U4/U6-U5 small nuclear ribonucleoprotein (snRNP) complex. This complex is essential for pre-mRNA splicing, a process that removes introns and connects exons together.

At this time, there is no treatment for RP, but medications can help treat complications. A medical professional can manage the condition to improve symptoms. There is support available for people living with RP and their families.
