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]

The RPGRIP1 c.808A>G; p.Ile270Val variant (rs372615343) is reported in the medical literature in an individual with an ocular development anomaly, but was not determined to be causative (Chassaing 2016). The variant is reported in the ClinVar database (Variation ID: 221937) and in the general population in 50 out of 205878 alleles. The amino acid at this position is moderately conserved across species but computational analyses (SIFT: Tolerated, PolyPhen-2: Probably Damaging) predict conflicting effects of this variant on protein structure/function. Considering available information, the clinical significance of this variant cannot be determined with certainty. References: Chassaing N et al. Targeted resequencing identifies PTCH1 as a major contributor to ocular developmental anomalies and extends the SOX2 regulatory network. Genome Res. 2016 Apr;26(4):474-85. -
