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]

This sequence change creates a premature translational stop signal (p.Arg981*) 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). This variant is present in population databases (rs780667159, gnomAD 0.0009%). This premature translational stop signal has been observed in individuals with Leber congenital amaurosis (PMID: 28041643, 30576320). ClinVar contains an entry for this variant (Variation ID: 438163). For these reasons, this variant has been classified as Pathogenic. -
