ClinVar
Submissions by phenotype
not provided Uncertain:1
This variant, c.65_67dup, results in the insertion of 1 amino acid(s) of the C1QC protein (p.Leu22dup), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs763912542, gnomAD 0.001%). This variant has not been reported in the literature in individuals affected with C1QC-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. -
