Description

This variant has not been reported in the literature in individuals affected with COL1A2-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. This variant is present in population databases (rs764720520, gnomAD 0.01%). This sequence change affects codon 850 of the COL1A2 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the COL1A2 protein.
