RCV000283281 | SCV000402491 | uncertain significance | Congenital stationary night blindness 1E | 2018-01-13 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. |

RCV001323545 | SCV001514464 | uncertain significance | not provided | 2022-10-25 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. 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"). ClinVar contains an entry for this variant (Variation ID: 322998). This variant has not been reported in the literature in individuals affected with GPR179-related conditions. This variant is present in population databases (rs755044433, gnomAD 0.007%). This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 1158 of the GPR179 protein (p.Asn1158Lys). |
| Ambry Genetics | RCV004021700 | SCV004877711 | uncertain significance | Inborn genetic diseases | 2023-12-12 | criteria provided, single submitter | clinical testing | The c.3474C>A (p.N1158K) alteration is located in exon 11 (coding exon 11) of the GPR179 gene. This alteration results from a C to A substitution at nucleotide position 3474, causing the asparagine (N) at amino acid position 1158 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
