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.

Pathogenic, criteria provided, single submitter	clinical testing	Victorian Clinical Genetics Services, Murdoch Childrens Research Institute	Oct 08, 2024	Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with congenital stationary night blindness (MIM#610445), retinitis pigmentosa 4 (MIM#613731) and retinitis punctata albescens (MIM#136880). (I) 0108 - This gene is associated with both recessive and dominant disease (OMIM). (I) 0115 - Variants in this gene are known to have variable expressivity. Variants associated with dominant conditions in this gene are known to have variable expressivity and age of onset (PMID: 26887858). (I) 0200 - Variant is predicted to result in a missense amino acid change from glutamic acid to lysine. (I) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD (v2) <0.01 for a recessive condition (12 heterozygotes, 0 homozygotes). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2) (5 heterozygotes, 0 homozygotes). (I) 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. (I) 0600 - Variant is located in the annotated 7 transmembrane receptor (rhodopsin family) domain (DECIPHER). (I) 0801 - This variant has strong previous evidence of pathogenicity in unrelated individuals. This variant has been pathogenic or likely pathogenic by clinical laboratories in ClinVar, and has been observed as homozygous in four unrelated families in the literature all with retinitis pigmentosa (PMID: 19960070, 26887858, 37165311). (SP) 0901 - This variant has strong evidence for segregation with disease. This variant segregates with disease in a large family retinitis pigmentosa (PMID: 19960070). (SP) 1002 - This variant has moderate functional evidence supporting abnormal protein function. Knock-in mice homozygous for this variant displayed rapid retinal degeneration (PMID: 23221340). (SP) 1207 - Parental origin of the variant is unresolved (by trio analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -

Experimental studies have shown that this missense change affects RHO function (PMID: 23221340). For these reasons, this variant has been classified as Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RHO protein function. ClinVar contains an entry for this variant (Variation ID: 13046). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 150 of the RHO protein (p.Glu150Lys). This variant is present in population databases (rs104893791, gnomAD 0.04%). This missense change has been observed in individuals with autosomal recessive retinitis pigmentosa (PMID: 19960070, 26887858). It has also been observed to segregate with disease in related individuals. -
