Variant summary
Our verdict is Pathogenic. Variant got 20 ACMG points: 20P and 0B. PS1_Very_StrongPM1PM2PM5PP3_StrongPP5_Moderate
The NM_000539.3(RHO):c.45T>A(p.Asn15Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N15S) has been classified as Pathogenic.

Likely pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 03, 2020 | This sequence change replaces asparagine with lysine at codon 15 of the RHO protein (p.Asn15Lys). The asparagine residue is highly conserved and there is a moderate physicochemical difference between asparagine and lysine. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.Asn15 amino acid residue in RHO. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 9483582, 8353500, 31100078). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This missense change has been observed in individual(s) with clinical features of autosomal dominant retinitis pigmentosa (PMID: 30538586, Invitae). This variant is not present in population databases (ExAC no frequency). - |
