Analytical Validity: Help
With our method we have identified two pathogenic mutations (compound heterozygous or homozygous) in the GCDH gene of 12 patients of a cohort of 12 non-related patients diagnosed with glutaric aciduria type 1 on the basis of clinical presentation in combination with a markedly deficient enzyme activity in cells as … View more
Assay limitations: Help
Whole gene testing includes analysis of all coding exons plus flanking intron sequences by Sanger sequencing. In principle, this method will identify all missense and nonsense mutations, small deletions, small duplications and small insertions located in the analysed fragments. The presence of large deletions or duplications, or pathogenic mutations located … View more
