RCV004768827 | SCV005381098 | uncertain significance | not specified | 2024-08-14 | criteria provided, single submitter | clinical testing | Variant summary: COL9A1 c.1666-10T>G alters a conserved nucleotide located at a position not widely known to affect splicing. Several computational tools predict a significant impact on normal splicing: Two predict the variant weakens a 3' acceptor site. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 5.6e-05 in 251388 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in COL9A1 causing COL9A1-Related Disorders, allowing no conclusion about variant significance. To our knowledge, no occurrence of c.1666-10T>G in individuals affected with COL9A1-Related Disorders and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 851181). Based on the evidence outlined above, the variant was classified as uncertain significance. |
