3-methylglutaconic aciduria, type VIIB Uncertain:1
Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. This variant has not been reported in the literature in individuals affected with CLPB-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change disrupts the translational stop signal of the CLPB mRNA. It is expected to extend the length of the CLPB protein by 23 additional amino acid residues. -
