426 Shyng et al. [204] have reported that H125Q, N188S, F591L, T1139M, R1215Q and G1382S generated functional channels in the absence of ATP, indicating that the lack or reduction of KATP channel sensitivity to MgADP is a common molecular defect associated with the disease.

23 Whereas compound mutations occur in approximately 13% of CHI patients,39 the simultaneous presence of two homozygous CHI mutations has to our knowledge only been reported in one patient, in which one of the mutations (N188S) was thought to be nonfunctional.40 In this report,we describe two patients with more than one suspected mutation in diffuse and focal disease and delineate the consequences these DNA variations have on KATP channel function.

2 We have studied the functional properties of novel SUR1 mutations identified in PHHI patients, including H125Q, N188S, F591L, T1139M, R1215Q, G1382S, and R1394H.

3 R1394H and F1388 SUR1, a previously identified PHHI mutation, resulted in no functional channels when coexpressed with Kir6.2 in COS cells, while H125Q, N188S, F591L, T1139M, R1215Q, and G1382S SUR1 generated functional channels in the absence of ATP.

75 The positions of the seven newly identified SUR1 mutations that are associated with the disease PHHI are shown in Fig. 1, including H125Q, N188S, F591L, T1139M, R1215Q, G1382S, and R1394H on both SUR1 topology models.

112 Compared with wild-type channels, H125Q had a slightlygreater response to diazoxide (P < 0.1, ANOVA), N188S hada response that is similar to the wild-type channel (NS, ANOVA), T1139M and G1382S mutant channels had slightly reduced responses, while F591L and R1215Q channels had severely reduced responses (P < 0.005 and 0.025, respectively, ANOVA) (Fig. 6).

156 With the exception of N188S and H125Q, which formed channels that were indistinguishable from the wild-type in terms of regulation of the channel by nucleotides and diazoxide, all other mutants caused defects of various severity in the resulting channels.

163 This is particularly true of the N188S mutation, which alters channel function only minimally in vitro but is associated with severe clinical disease.

200 A model for SUR1 (29) predicts that the remaining seven missense mutations (Arg74Gln, His125Gln, Asn188Ser, Asn406Asp, Phe591Leu, Thr1139Met, Arg1215Gln) are located either within transmembrane segments or are present on the extracellular or cytoplasmic loops connecting adjacent trans- membranehelices.Theidentificationofthesemissensemutations in HI patients provides a basis for further studies to elucidate the functions of these transmembrane domains in SUR1 and KATP channel activity.
