Variant summary

Our verdict is Pathogenic. The variant received 17 ACMG points: 17P and 0B. PM1 PM2 PM5 PP2 PP3_Moderate PP5_Very_Strong

The NM_001354768.3(NRL):​c.148T>C​(p.Ser50Pro) variant causes a missense change involving the alteration of a 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 variant affecting the same amino acid position, but resulting in a different missense (i.e. S50T) has been classified as Pathogenic.

Genes affected

NRL (HGNC:8002): (neural retina leucine zipper) This gene encodes a basic motif-leucine zipper transcription factor of the Maf subfamily. The encoded protein is conserved among vertebrates and is a critical intrinsic regulator of photoceptor development and function. Mutations in this gene have been associated with retinitis pigmentosa and retinal degenerative diseases. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Pathogenic. The variant received 17 ACMG points.

• PM1: In a hotspot region, there are 6 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 8 uncertain in NM_001354768.3
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr14-24082701-A-T is described in ClinVar as Pathogenic. ClinVar VariationId is 14042.Status of the report is no_assertion_criteria_provided, 0 stars.
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 10 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 0.61398 (below the threshold of 3.09). Trascript score misZ: -0.58033 (below the threshold of 3.09). GenCC associations: The gene is linked to retinitis pigmentosa 27, retinitis pigmentosa, enhanced S-cone syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.864
• PP5: Variant 14-24082701-A-G is Pathogenic according to our data. Variant chr14-24082701-A-G is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 2137571.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
