Invitae RCV000464806 SCV000541788 uncertain significance Ehlers-Danlos syndrome, type 4 2019-07-12 criteria provided, single submitter clinical testing This sequence change falls in intron 5 of the COL3A1 gene. It does not directly change the encoded amino acid sequence of the COL3A1 protein. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a COL3A1-related disease. Nucleotide substitutions within the consensus splice site are relatively common causes of aberrant splicing (PMID: 17576681, 9536098) but according to multiple splice site algorithms, this particular variant is not predicted to significantly affect splicing. These predictions have not been confirmed by published functional studies. In summary, this is a novel intronic change with uncertain impact on splicing. It has been classified as a Variant of Uncertain Significance.

Integrated Genetics/Laboratory Corporation of America RCV000512993 SCV000695376 uncertain significance not provided 2016-12-25 criteria provided, single submitter clinical testing Variant summary: c.528+5G>A in COL3A1 gene is an intronic change that involves a highly conserved nucleotide. 5/5 programs in Alamut predict that this variant eliminates the donor splice site, however no functional studies supporting this notion were published at the time of evaluation. The variant is absent from control population dataset of ExAC. The variant of interest has not, to our knowledge, been reported in affected individuals in published reports but is cited as VUS by a reputable database/clinical laboratory. Considering all, due to the lack of sufficient clinical information on carriers and absence of functional studies the variant has been currently classified as a variant of uncertain significance until additional information becomes available.
