T1 |
0-100 |
Sentence |
denotes |
Vitamin D-binding protein gene polymorphism association with IA-2 autoantibodies in type 1 diabetes. |
T2 |
101-112 |
Sentence |
denotes |
BACKGROUND: |
T3 |
113-239 |
Sentence |
denotes |
Vitamin D-binding protein (DBP) is the main systemic transporter of 1.25(OH)2D3 and is essential for its cellular endocytosis. |
T4 |
240-497 |
Sentence |
denotes |
There are two known polymorphisms in exon 11 of the DBP gene resulting in amino acid variants: GAT-->GAG substitution replaces aspartic acid by glutamic acid in codon 416; and ACG-->AAG substitution in codon 420 leads to an exchange of threonine for lysine. |
T5 |
498-569 |
Sentence |
denotes |
These DBP variants lead to differences in the affinity for 1.25(OH)2D3. |
T6 |
570-668 |
Sentence |
denotes |
Correlations between DBP alleles and type 1 diabetes have been described in different populations. |
T7 |
669-804 |
Sentence |
denotes |
Therefore, we investigated the polymorphism in codon 416 of the DBP gene for an association with autoimmune markers of type 1 diabetes. |
T8 |
805-824 |
Sentence |
denotes |
DESIGN AND METHODS: |
T9 |
825-871 |
Sentence |
denotes |
The present analysis was a case control study. |
T10 |
872-983 |
Sentence |
denotes |
110 patients, 68 controls, and 115 first-degree relatives were genotyped for the DBP polymorphism in codon 416. |
T11 |
984-1088 |
Sentence |
denotes |
DNA typing of DBP locus was performed by the PCR-restriction fragment length polymorphism method (RFLP). |
T12 |
1089-1097 |
Sentence |
denotes |
RESULTS: |
T13 |
1098-1234 |
Sentence |
denotes |
The frequencies of the Asp/Glu and Glu/Glu were significantly increased in diabetic subjects with detectable IA-2 antibodies (P < 0.01). |
T14 |
1235-1357 |
Sentence |
denotes |
On the contrary, the DBP Glu-containing genotype was not accompanied by differences in the prevalence of GAD65 antibodies. |
T15 |
1358-1467 |
Sentence |
denotes |
These finding supports a role of the vitamin D endocrine system in the autoimmune process of type 1 diabetes. |
