234 However, activating mutations in these NBD regions have now been reported (e.g. R826W, R1380C/H/L and V1523A/L) that could act to enhance the stimulatory effect of magnesium nucleotide binding or reduce the hydrolysis rate of Mg-ATP [16]. Login to comment

37 Transient neonatal diabetes mutations KCNJ11/R50H, KCNJ11/E229K, and ABCC8/R1380C have been previously reported [14], while ABCC8 mutations in same residue as ours, but with different amino acid change such as V1523A/L have been described associated with permanent neonatal diabetes [14].
