Genes affected

RPGRIP1 (HGNC:13436): (RPGR interacting protein 1) This gene encodes a photoreceptor protein that interacts with retinitis pigmentosa GTPase regulator protein and is a key component of cone and rod photoreceptor cells. Mutations in this gene lead to autosomal recessive congenital blindness. [provided by RefSeq, Oct 2008]

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1069749). This variant has not been reported in the literature in individuals affected with RPGRIP1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Asp11Glyfs*10) in the RPGRIP1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RPGRIP1 are known to be pathogenic (PMID: 11528500, 23105016). -
