Description

This sequence change creates a premature translational stop signal (p.Ile969Tyrfs*29) in the CRB1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CRB1 are known to be pathogenic (PMID: 10508521, 22065545, 23379534, 25412400, 26957898, 28041643, 29391521). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CRB1-related conditions. For these reasons, this variant has been classified as Pathogenic.
