RCV001098215 | SCV001254566 | uncertain significance | Geroderma osteodysplastica | 2018-01-12 | 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. |
Invitae | RCV000288907 | SCV002215582 | uncertain significance | not provided | 2022-10-17 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 234 of the GORAB protein (p.Arg234Trp). This variant is present in population databases (rs138502097, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with GORAB-related conditions. ClinVar contains an entry for this variant (Variation ID: 288166). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. |

RCV003422200 | SCV004116992 | uncertain significance | GORAB-related disorder | 2023-08-28 | criteria provided, single submitter | clinical testing | The GORAB c.700C>T variant is predicted to result in the amino acid substitution p.Arg234Trp. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.050% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/1-170513949-C-T). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
Ambry Genetics | RCV004021244 | SCV004878685 | uncertain significance | Inborn genetic diseases | 2021-11-08 | criteria provided, single submitter | clinical testing | The c.700C>T (p.R234W) alteration is located in exon 4 (coding exon 4) of the GORAB gene. This alteration results from a C to T substitution at nucleotide position 700, causing the arginine (R) at amino acid position 234 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
