RCV000695406 | SCV000823903 | uncertain significance | Ehlers-Danlos syndrome, type 4 | 2023-12-24 | criteria provided, single submitter | clinical testing | This sequence change falls in intron 24 of the COL3A1 gene. It does not directly change the encoded amino acid sequence of the COL3A1 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs189483688, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with COL3A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 573680). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. |

RCV001187143 | SCV001353835 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2023-10-12 | criteria provided, single submitter | clinical testing | This variant is located in the intron 24 splice donor region of the COL3A1 gene. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with COL3A1-related disorders in the literature. This variant has been identified in 18/250454 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |

RCV002499245 | SCV002812168 | uncertain significance | Ehlers-Danlos syndrome, type 4; Polymicrogyria with or without vascular-type Ehlers-Danlos syndrome | 2021-07-22 | criteria provided, single submitter | clinical testing | |
Ambry Genetics | RCV001187143 | SCV003715078 | likely benign | Familial thoracic aortic aneurysm and aortic dissection | 2022-01-18 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |
