Metabolic-associated steatotic liver disease (MASLD) encompasses common comorbidities including low bone mineral density (BMD) and hyperuricemia (HU), yet relevant genetic analyses are limited. This study aimed to investigate the genetic effects of risk single nucleotide polymorphisms (SNPs) on the occurrence of low BMD in patients with MASLD and HU, particularly focusing on relatively young or non-obese populations. We conducted a cross-sectional study utilizing data from the Taiwan Biobank, screening a total of 150,709 participants who were prospectively enrolled over a period of 13 years. The risk SNPs for MASLD were identified. Genotype analyses of HU and its effects on the occurrence of low BMD in the general population were evaluated, with further analyses of common SNPs focusing on patients with MASLD, including subgroup analyses on relatively young and non-obese populations. A total of 20,496 participants were eligible for analysis, including 7526 patients with MASLD. Several risk SNPs for MASLD were identified. Furthermore, MASLD patients carrying the PNPLA3-rs738409 C_C, PNPLA3-rs2896019 T_T, GCKR-rs780094 T_T, and GCKR-rs1260326 T_T genotypes exhibited an increased risk of comorbidity with HU. Trend analysis revealed that the T alleles in GCKR-rs780094 and GCKR-rs1260326 were associated with the occurrence of low BMD in MASLD individuals comorbid with HU, particularly among relatively young or non-obese populations. In relatively young, non-obese patients with MASLD and HU, genetic effects significantly increase the risk of occurrence of low BMD. Given the presence of genetic effects in these ostensibly low-risk groups, heightened awareness and close follow-up are recommended.
代谢相关脂肪性肝病(MASLD)包含常见的合并症,如低骨密度(BMD)和高尿酸血症(HU),但相关的基因分析有限。本研究旨在探讨风险单核苷酸多态性(SNP)对MASLD和HU患者低BMD发生的遗传影响,特别关注相对年轻或非肥胖人群。我们利用台湾生物银行的数据进行了一项横断面研究,筛选了在13年期间前瞻性招募的总共150,709名参与者。确定了MASLD的风险SNP。评估了HU的基因型分析及其对一般人群中低BMD发生的影响,并对MASLD患者的常见SNP进行了进一步分析,包括对相对年轻和非肥胖人群的亚组分析。共有20,496名参与者符合分析条件,其中包括7526名MASLD患者。确定了几个MASLD的风险SNP。此外,携带PNPLA3-rs738409 C_C、PNPLA3-rs2896019 T_T、GCKR-rs780094 T_T和GCKR-rs1260326 T_T基因型的MASLD患者合并HU的风险增加。趋势分析显示,GCKR-rs780094和GCKR-rs1260326中的T等位基因与合并HU的MASLD个体中低BMD的发生有关,特别是在相对年轻或非肥胖人群中。在相对年轻、非肥胖的MASLD和HU患者中,遗传效应显著增加了低BMD发生的风险。鉴于这些表面上低风险群体中存在遗传效应,建议提高认识并密切随访。
