- Results obtained by qPCR are compared to the diagnosis of 22q11DS obtained by FISH using the TUPLE1 gene. Specificity of diagnosis calls for qPCR was 58.6% as ddPCR results, conducted in a subgroup of 40 individuals (29 with 22q11DS and 11 TD) correctly identified 1 copy of the TUPLE1 gene only in 17 individuals with 22q11DS.
