RCV000124395 | SCV000167828 | benign | not specified | 2014-02-02 | criteria provided, single submitter | clinical testing | This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. |

RCV000124395 | SCV001437255 | benign | not specified | 2020-09-24 | criteria provided, single submitter | clinical testing | Variant summary: COL3A1 c.80-16C>T alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 4/4 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.0022 in 250658 control chromosomes, predominantly at a frequency of 0.031 within the African or African-American subpopulation in the gnomAD database, including 4 homozygotes. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 20666 fold of the estimated maximal expected allele frequency for a pathogenic variant in COL3A1 causing Ehlers-Danlos Syndrome, Vascular Type phenotype (1.5e-06), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. To our knowledge, no occurrence of c.80-16C>T in individuals affected with Ehlers-Danlos Syndrome, Vascular Type and no experimental evidence demonstrating its impact on protein function have been reported. One ClinVar submitter (evaluation after 2014) cite the variant as benign. Based on the evidence outlined above, the variant was classified as benign. |
