GeneDx RCV000181117 SCV000233393 likely pathogenic Familial thoracic aortic aneurysm and aortic dissection 2014-03-01 criteria provided, single submitter clinical testing c.798_798+1delAG in exon/intron 10 of the COL3A1 gene (NM_000090.3). The normal sequence with the bases that are deleted in braces is: ACAG{Ag}taagt, whereby upper case letters indicate exonic sequence and lower case letters indicate intronic sequence. Although the c.798_798+1delAG mutation has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge, this mutation damages the canonical splice donor site in intron 10 and is predicted to lead to either an abnormal message that is subject to nonsense-mediated mRNA decay, or to an abnormal protein product if the message is used for protein translation. Other splice site mutations in the COL3A1 gene have been reported in association with EDS type IV. In summary, c.798_798+1delAG in the COL3A1 gene is interpreted as a likely disease-causing mutation. The variant is found in TAAD panel(s).
