Ambry Genetics | RCV002313842 | SCV000738557 | pathogenic | Familial thoracic aortic aneurysm and aortic dissection | 2022-10-14 | criteria provided, single submitter | clinical testing | The p.R1024* pathogenic mutation (also known as c.3070C>T), located in coding exon 42 of the COL3A1 gene, results from a C to T substitution at nucleotide position 3070. This changes the amino acid from an arginine to a stop codon within coding exon 42. This alteration was reported in a family with vascular Ehlers-Danlos syndrome (Leistritz DF et al. Genet. Med., 2011 Aug;13:717-22). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. |

RCV000087411 | SCV002237245 | pathogenic | Ehlers-Danlos syndrome, type 4 | 2024-03-26 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Arg1024*) in the COL3A1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in COL3A1 are known to be pathogenic (PMID: 24922459). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with clinical features of COL3A1-related conditions (PMID: 21637106). ClinVar contains an entry for this variant (Variation ID: 101174). For these reasons, this variant has been classified as Pathogenic. |
