Genes affected

RHO (HGNC:10012): (rhodopsin) The protein encoded by this gene is found in rod cells in the back of the eye and is essential for vision in low-light conditions. The encoded protein binds to 11-cis retinal and is activated when light hits the retinal molecule. Defects in this gene are a cause of congenital stationary night blindness.

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Null variant is predicted to cause nonsense-mediated decay in a gene where LOF is a known cause of pathogenicity (PVS1). Variant allele frequency is less than 0.0001 in gnomAD exomes and absent from genomes (PM2). Experimental studies done by transfecting human rhodopsin nonsense mutants into HEK-293T and HT-1080 human cells indicated that this nonsense variant yielded significantly reduced levels of rhodopsin mRNA, approximately 40% lower than for wild type rhodopsin. The results also suggested that the NMD pathway is responsible for the degradation of rhodopsin mRNA in the mutants causing arRP (PS3, PMID:26416182) -

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Trp161*) in the RHO gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RHO are known to be pathogenic (PMID: 1303237, 21174529). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with autosomal recessive retinitis pigmentosa (PMID: 21174529). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 29875). For these reasons, this variant has been classified as Pathogenic. -
