The products were compared to healthy controls in order to detect variants. gDNA, in order to determine the size of deletions in patient 3 and 4 , a set of intronic primers presumably flanking the deletions was used and specific primers allowed sequencing of exactly those critical regions(sequencing on paper). To estimate the relevance of the identified intronic variants in terms of their capability to induce splicing, we used a score developed by Shapiro and Senapathy.

PCR products were then purified and bidirectionally sequenced. The library was sequenced using Illumina HiSeq4000 and generated 150 bp paired-end reads. Data analysis was performed as previously described [Sun Y, Hu G, Liu H, Zhang X, Huang Z, Yan H, et al. Further delineation of the phenotype of truncating KMT2A mutations: the extended Wiedemann–Steiner syndrome. Am J Med Genet A. 2017;173:510–4.]. Multiplex ligation-dependent probe amplification analysis was performed for samples in which Sanger sequencing or WES failed to detect any disease-causing mutation.
