Hereditary spastic paraplegia 49 Pathogenic:1
For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. This variant has not been reported in the literature in individuals affected with TECPR2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change creates a premature translational stop signal (p.Tyr17*) in the TECPR2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TECPR2 are known to be pathogenic (PMID: 23176824, 25590979). -
