Abstract

Aims

We examined the association of the G allele in the single-nucleotide polymorphism (SNP) rs738409 in the third exon of patatin-like phospholipase domain-containing 3 gene (PNPLA3) gene, with chronic kidney disease in diabetes endotypes.

Methods

Participants with recent-onset diabetes (n = 707) from the prospective German Diabetes Study (GDS) underwent cluster assignment, detailed phenotyping, genotyping and magnetic resonance spectroscopy to quantify hepatocellular lipid content (HCL).

Results

Severe insulin-resistant diabetes (SIRD) had the lowest glomerular filtration rates (eGFR) and highest HCL compared to severe insulin-deficient, moderate obesity-related, moderate age-related and severe autoimmune diabetes endotypes (all p < 0.05). HCL was negatively associated with eGFR (r = −0.287, p < 0.01) across all groups. Stratification by G-allele carrier status did not reveal any association between HCL and eGFR among the endotypes. However, the proportion of G-allele carriers increased from 44 % for eGFR >60 ml/min to 52 % for eGFR <60 ml/min (p < 0.05).

Conclusions

The PNPLA3 polymorphism may contribute to declining kidney function independently of liver lipids.

含拍蛋白样磷脂酶域的 3 基因在降低新诊断糖尿病患者肾功能中的作用

目的：我们研究了单核苷酸多态性（SNP）rs738409中的G等位基因与糖尿病内型中慢性肾脏疾病的关系：方法：对前瞻性德国糖尿病研究（GDS）中新近发病的糖尿病患者（n = 707）进行分组、详细表型分析、基因分型和磁共振波谱分析，以量化肝细胞脂质含量（HCL）：结果：与重度胰岛素缺乏、中度肥胖相关、中度年龄相关和重度自身免疫性糖尿病内型相比，重度胰岛素抵抗性糖尿病（SIRD）的肾小球滤过率（eGFR）最低，HCL最高（eGFR结论均为60毫升/分钟至52%）：PNPLA3多态性可能会导致肾功能下降，而与肝脏血脂无关。
