Description

For these reasons, this variant has been classified as Pathogenic. This variant disrupts the C-terminus of the RP1 protein. Many variants that disrupt this region have been reported in individuals with either autosomal dominant or autosomal recessive retinitis pigmentosa (PMID: 11527933, 19933189, 29425069, 30027431). Therefore, variants that disrupt this region are expected to be disease-causing. This variant has not been reported in the literature in individuals affected with RP1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Lys1266Argfs*28) in the RP1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 891 amino acid(s) of the RP1 protein.
