SDHB and cancer: Section 3 of this review describes different ailments such as cancer caused by mutations in SDH subunits, including SDHB, which signifies the importance of studying the effects of RNA-editing enzymes on SDH. It is important to note that RNA editors can also affect the processing of non-coding RNAs, as seen with increased A-to-I editing in miR-376 which changes the targets of miR-376 [93].
