Whole-exome sequencing with the genomic DNA from peripheral blood leukocytes showed that patient 1 with INF2 p.Gly73Asp had no germline, schwannomatosis-related gene variants including 22q loss of heterozygosity (LOH), NF1, NF2, LZTR1, SMARCB1, and COQ6 (Supplementary Table S2, Supplementary Figure S2). Here, LZTR1 is linked to schwannomatosis.
