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.Lys372Asnfs*3) 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 (rs776880045, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with Leber congenital amaurosis (PMID: 28041643). ClinVar contains an entry for this variant (Variation ID: 438160). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
