|Test Details||Extraction of DNA, capture of the genes to be assayed, and sequencing on the Illumina platform. Identified variants are categorized as pathogenic, likely pathogenic, variant of unknown significance, likely benign, or benign. An interpretation of results is provided based on the medical literature and in the context of the indication for testing. aCGH send out testing for the ALMS1 gene is performed when NGS does not identify any pathogenic or likely pathogenic variants.|
