Diabetes mellitus was characterised as follows: (1) it was strictly insulin-dependent and ketosis-prone, (2) the average insulin requirement was 1 U/kg body weight, (3) the HLA haplotype was not typical of Type 1 (insulin-dependent) diabetes mellitus, (4) there were no positive immune parameters typical of Type 1 diabetes at the clinical onset of diabetes mellitus and (5) there was no remission.

|
To investigate the genetic component of multifactorial diseases such as type 1 (insulin-dependent) diabetes mellitus (IDDM), models involving the joint action of several disease loci are important.
|
4 |
7573054
|
The method is applied to affected-sib-pair data, and the joint effects of IDDM1 (HLA) and IDDM2 (the INS VNTR) and of IDDM1 and IDDM4 (FGF3-linked) are assessed with relation to the development of IDDM.
|

7573054
|
Analysis of these families indicates that the effects at IDDM1 and IDDM2 are well described by a multiplicative genetic model, while those at IDDM1 and IDDM4 follow a heterogeneity model.

In the human, in addition to HLA and INS, two new susceptibility genes have been localized, IDDM4 on chromosome 11q and IDDM5 on 6q, demonstrating the polygenic nature of type 1 diabetes and the role of HLA as the major locus.

Affected sibling pair linkage analysis revealed strong evidence for an IDDM susceptibility locus near D15S107 on chromosome 15q26 (P = 0.0010) termed IDDM3.
|
21 |
7842018
|
Our study also revealed evidence for an IDDM locus on chromosome 11q13 (IDDM4) using affected siblings (P = 0.0043), but no evidence using discordant siblings.

|
In addition to IDDM1 (in the major histocompatibility complex on chromosome 6p21) and IDDM2 (in the insulin gene region on chromosome 11p15), eighteen different chromosome regions showed some positive evidence of linkage to disease.
|
23 |

Linkages to chromosomes 11q (IDDM4) and 6q (IDDM5) were confirmed by replication, and chromosome 18 may encode a fifth disease locus.

|
26 |

|
Previous genome-wide mapping studies have provided suggestive linkage evidence for several novel susceptibility loci responsible for insulin-dependent diabetes mellitus (IDDM); however, the evidence was not sufficient to confirm the existence of these genes.
|
27 |
8733139
|
The maximum LOD scores (MLS) were 3.9, 4.5 and 3.6 in our data set, and 5.0, 4.6 and 5.0 for our data combined with non-overlapping data from the literature, for IDDM4 on chromosome 11q13, IDDM5 on 6q25, and IDDM8 on 6q27, respectively.
|
28 |

However, we could not confirm linkage for IDDM3 on 15q26 and IDDM7 on 2q31-q33, or linkage disequilibrium between D2S152 and IDDM7.

It is recognized that the MHC contains multiple susceptibility loci (referred to collectively as IDDM1), including the class II antigen receptor genes, which control the major pathological feature of the disease: T-lymphocyte-mediated autoimmune destruction of the insulin-producing pancreatic beta cells.
|
34 |
8875250
|
However, the MHC genes, and a second locus, the insulin gene minisatellite on chromosome 11p15 (IDDM2; lambda S = 1.25), cannot account for all of the observed clustering of disease in families (lambda S = 15), and the scans suggested the presence of other susceptibility loci scattered throughout the genome.
|

|
There are four additional loci for which there is currently sufficient evidence from linkage and association studies to justify fine mapping experiments: IDDM4 (FGF3/11q13), IDDM5 (ESR/6q22), IDDM8 (D6S281/6q27) and IDDM12 (CTLA-4/2q33).

IDDM4, 5 and 8 were detected by genome scanning, and IDDM12 by a candidate gene strategy.

The identification of aetiological determinants requires exclusion of hitchhiking polymorphisms in regions of linkage disequilibrium, as demonstrated for the MHC and the insulin gene loci, and functional studies implicating the disease-associated variant in pathogenesis.

Fas-associated death domain protein (FADD)/MORT1 is a 23-kDa cytoplasmic protein containing a C-terminal death domain that interacts with the intracellular death domain of the Fas transmembrane receptor.
|
44 |

|
Now that it has been colocalized in 11q13.3 with IDDM4, a diabetes susceptibility locus, alterations in FADD should also be considered as potential contributors to insulin-dependent familial diabetes.

The results from the CASPAR analysis suggest that conditioning of IDDM5 on IDDM1 and IDDM4, and of IDDM7 on IDDM1 and IDDM2 provides significant benefits for the genetic analysis of polygenic loci.

The map encompasses all the candidate loci of Bardet-Biedle syndrome type I (BBS1) and spinocerebellar ataxia type 5 (SCA5), one-third of the distal region for hereditary paraganglioma 2 (PGL2), and one-third of the central region for insulin-dependent diabetes mellitus 4 (IDDM4).

By several crossing studies it has been demonstrated that the MHC class-II genes of the RT1u haplotype, Iddm1, and the lymphopenia, Iddm2, are essential, but not sufficient for diabetes development in the BB rat.
|
53 |
9571179
|
The genetic analysis of Iddm1 and Iddm2 homozygous [(BB/OK x SHR)F1 x BB/OK] first backcross hybrids (BC1) confirmed the action of Iddm3 and one predisposing non-MHC locus, Iddm4, near Ighe/D6Mgh2 on chromosome 6 and one protective locus, Iddm5r(esistance), detected around Igf2/Tnt on chromosome 1.

A gene encoding a novel transmembrane protein was identified by DNA sequence analysis within the insulin-dependent diabetes mellitus (IDDM) locus IDDM4 on chromosome 11q13.
|
55 |

|
The gene, termed low-density lipoprotein receptor related protein 5 (LRP5), encodes a protein of 1615 amino acids that contains conserved modules which are characteristic of the low-density lipoprotein (LDL) receptor family.
|
56 |
9714764
|
These modules include a putative signal peptide for protein export, four epidermal growth factor (EGF) repeats with associated spacer domains, three LDL-receptor (LDLR) repeats, a single transmembrane spanning domain, and a cytoplasmic domain.
|
57 |
9714764
|
The encoded protein has a unique organization of EGF and LDLR repeats; therefore, LRP5 likely represents a new category of the LDLR family.
|

Several crossing studies using diabetic BB/OK and diabetes-resistant rat strains have clearly shown that the MHC class-II-genes of the RT1u haplotype (Iddm1) and the lymphopenia (Iddm2) are essential but not sufficient for type 1 diabetes development.

Continuing progress has been made in elucidating the genetic factors involved in type 1 diabetes (insulin-dependent diabetes mellitus [IDDM]) in the past year.

Although significant and consistent linkage evidence was reported for the susceptibility intervals IDDM8 (on human chromosome 6q27), IDDM4 (on 11q) and IDDM5 (on 6q25), evidence for most other intervals varies in different data sets -probably due to a weak effect of the disease genes, genetic heterogeneity or random variation.
|
62 |

|
Functional studies indicate, firstly, that the susceptible and protective HLA class II molecules HLA-DR and -DQ bind and present nonoverlapping peptides and, secondly, that the variable number of tandem repeats at the 5' end of the insulin gene (susceptibility interval IDDM2) regulates insulin expression in the thymus.

By using a single microsatellite marker at each locus, we screened the type 1 diabetes loci IDDM4, IDDM5, IDDM6, IDDM8, and IDDM10 and the fucosyltransferase-2 locus for linkage in sib pairs with GD.

However, ETDT did reveal significant association/linkage with the marker D11S987 (P=0.0004) within the IDDM4 interval defined by ASP analyses, suggesting that IDDM4 may be in the close proximity of D11S987.

Analysis of cross hybrids of diabetic BB/OK rats and rats of different diabetes-resistant strains has demonstrated that beside the MHC genes, Iddm1 and the lymphopenia, Iddm2, additional non-MHC genes are involved in diabetes development.

To study the importance of the non-MHC genes, Iddm4 and Iddm3, two congenic BB.SHR rat strains were generated by recombining a segment of the SHR chromosome 6 (Iddm4; termed BB.6S; 15cM) or chromosome 18 (Iddm3; termed BB.18S; 24cM) into the BB/OK background by serial backcrossing and marker-aided selection.
