7 Five mutations were novel: two (p.A174G and p.C166Y) in KCNJ11, two (p.A90V and p.N1122D) in ABCC8, and one (p.P367L) in FOXP3. Login to comment
56 The novel mutations were the substitution of alanine by valine at codon 90 (c.269CϾT, p.A90V) and the substitution of asparagine by aspartate at codon 1122 (c.3364AϾG, p.N1122D). Login to comment
