A few micro RNAs genes are present in the NF1 type-1 deletion interval: MIR4733, MIR4724, MIR193A, MIR4725, and MIR365B. miR-193a has well-known tumour suppressor functions, in hepatocellular carcinoma [65], endometrioid endometrial adenocarcinoma [66], non-small-cell lung cancer [67], and breast cancer [68]. The gene discussed is NF1; the disease is breast cancer.
