Furthermore, due to facial dysmorphism, a genetic disorder was suspected, and a molecular genetic test for the causal genes of RASopathies (PTPN11, SOS1, RAF1, RIT1, HRAS, KRAS, NRAS, BRAF, MAP2K1, MAP2K2, CBL, RRAS, and SHOC2) was performed. This evidence concerns the gene RRAS and hereditary disease.
