Description

DNA sequence analysis of the ABCC8 gene demonstrated a sequence change, c.4136G>T, in exon 34 that results in an amino acid change, p.Arg1379Leu. The p.Arg1379Leu change has been identified in patients with transient neonatal diabetes and family members of these individuals who were diagnosed with diabetes in adulthood (PMID: 18025464). Additionally, several other mutations affecting the same amino acid residue (p.Arg1379Cys, p.Arg1379His, p.Arg1379Pro, p.Arg1379Ser) have been reported in patients with neonatal diabetes as well as adult onset diabetes (PMIDs: 18025464, 16885549, 24622368, 25555642). The p.Arg1379Leu change is absent from large population databases such as ExAC and gnomAD. The p.Arg1379Leu change affects a highly conserved amino acid residue located in a domain of the SUR1 protein that is known to be functional. The p.Arg1379Leu substitution appears to be deleterious using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL).
