3billion | RCV002251148 | SCV002521601 | uncertain significance | Fraser syndrome 2 | 2022-05-22 | criteria provided, single submitter | clinical testing | The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.017%). Protein truncation variants are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.67; 3Cnet: 0.10). Therefore, this variant is classified as uncertain significanceaccording to the recommendation of ACMG/AMP guideline. |

RCV003094083 | SCV003265416 | uncertain significance | not provided | 2022-07-06 | criteria provided, single submitter | clinical testing | This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 1384 of the FREM2 protein (p.His1384Tyr). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with FREM2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1687466). 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"). 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. |

RCV003395433 | SCV004119953 | uncertain significance | FREM2-related disorder | 2023-04-12 | criteria provided, single submitter | clinical testing | The FREM2 c.4150C>T variant is predicted to result in the amino acid substitution p.His1384Tyr. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.14% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/13-39265631-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. |
