Patient AA-3 had somatic mutations in several genes, including KRAS, NFATC2, PTPN22, TNFAIP3, and JAGN1. KRAS A146P, JAGN1 T473A, and TNFAIP3 D212fs mutations were predicted to be pathogenic, and same KRAS mutation has been found in several hematologic neoplasms (genomic mutation ID in COSMIC v91: COSV55541748). Here, PTPN22 is linked to hematopoietic and lymphoid system neoplasm.
