GeneDx	RCV000428349	SCV000521210	pathogenic	not provided	2017-01-09	criteria provided, single submitter	clinical testing	The R1189X variant in the RPGRIP1 gene has been reported previously with unspecified zygosity in two unrelated individuals with familial non-syndromic cone-rod dystrophy (Patel et al., 2016) and in the homozygous state in three unrelated patients with Leber congenital amaurosis (Abu-Safieh et al., 2013). This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The R1189X variant was not observed in approximately 6000 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. We interpret R1189X as a pathogenic variant.

This variant has been observed in individual(s) with retinal dystrophies (PMID: 23105016, 24123792, 26355662). ClinVar contains an entry for this variant (Variation ID: 381684). Loss-of-function variants in RPGRIP1 are known to be pathogenic (PMID: 11528500, 23105016). This sequence change creates a premature translational stop signal (p.Arg1189*) in the RPGRIP1 gene. It is expected to result in an absent or disrupted protein product. For these reasons, this variant has been classified as Pathogenic.
