GeneDx RCV000196302 SCV000250019 uncertain significance not specified 2017-01-04 criteria provided, single submitter clinical testing The R1106W variant in the COL5A2 gene has not been reported as a disease-causing variant or as a benign polymorphism to our knowledge. The NHLBI Exome Sequencing Project and the 1000 Genomes Project reports R1106W was observed in 0.4% to 0.9% of alleles from individuals of African American ancestry, indicating it may be a rare benign variant in this population. In addition, no missense variants in nearby residues have been reported in association with EDS, classic type indicating this region of the protein may be tolerant of change. Nevertheless, R1106W results in a non-conservative amino acid substitution of a positively-charged Arginine with a neutral Tryptophan at a position that is well conserved across species. Furthermore, in silico analysis predicts this variant is probably damaging to the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
