Inborn errors of metabolism (IEM) are caused by defects in the production and breakdown of proteins, fats, and carbohydrates. Micro ribonucleic acids (miRNAs) are short non-coding RNA molecules, ⁓19-25 nucleotides long, hairpin-shaped, produced from DNA. They play key roles in regulating gene expression of target mRNAs at both transcriptional and post-transcriptional levels. Altered expression of miRNAs has emerged as an additional molecular mechanism implicated in the pathogenesis of many diseases, this altered miRNA expression is also present in inherited metabolic diseases. A single miRNA can regulate targets associated with similar cellular processes and pathways, making miRNAs powerful therapeutics to restore the impaired cellular functions seen in disease phenotypes by enhancing the cellular response. Although the miRNA research field has advanced significantly in recent years, studies in IEM are still limited. Further research on miRNA expression specifically related to IEM may allow the identification of new biomarkers for the diagnosis, progression, and prognosis of diseases. In this review, the literature studies between miRNAs and IEMs, diagnosis, prognosis, follow-up, and treatment possibilities of miRNAs were analyzed.

This study aimed to determine whether promoter methylation levels of 12 diabetes and obesity susceptibility genes are associated with MetS phenotypes and risk of T2DM in Pakistani individuals.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Study design: &lt;/strong&gt;A cross-sectional study was undertaken whereby methylation-specific PCR assays were conducted on 203 adult subjects recruited from the community in Karachi, Pakistan. Participants were stratified into four groups based on their metabolic health and BMI (MOU n = 39, MHO n = 43, MUHNW n = 51, MHNW n = 70). Biochemical and biophysical data were statistically analyzed to determine the association of methylation levels with MetS phenotypes.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Low chemerin promoter methylation was observed in metabolically unhealthy participants, irrespective of BMI, while higher methylation levels were observed for POMC and PCSK1. Unsupervised machine learning showed that the methylation status of Chemerin, IGF2, POMC, PCSK1 (P &lt; .001), and FNDC (P &lt; .05) was independently linked with the risk of developing MetS. Hierarchical clustering analysis revealed distinct genetic clusters that partially aligned with the original MetS and BMI categories, indicating the presence of unique genetic profiles and the potential misdiagnosis of high-risk individuals.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;Chemerin, IGF2, POMC, PCSK1, and FNDC's methylation status shows independently linked trends with the risk of developing MetS and obesity. Distinct genetic clusters for MUHNW and MHO exhibit similar phenotypic profiles, implying misdiagnosis risks and comparable risks of developing cardiometabolic disorders in the future. Large-scale methylation studies are needed to confirm the association. Key message What is already known on this topic:  Genetic susceptibility contributes significantly to complex disorders like obesity, diabetes, and MetS. Prior research has highlighted the role of genetic polymorphisms but hasn't extensively explored the influence of promoter methylation in Pakistani populations. Understanding genetic and epigenetic factors in disease etiology is crucial for tailored interventions, particularly in populations with diverse genetic backgrounds and environmental exposures. What this study adds:  Distinct trends of methylation patterns were observed in genes like Chemerin, IGF2, POMC, PCSK1, and FNDC, independently linked with MetS and obesity risk. Potential misdiagnosis risks and comparable risks of developing cardiometabolic disorders in individuals with metabolically unhealthy normal weight individuals and metabolically healthy phenotypes were observed.

It highlights that both leukocyte and overall telomere length are important factors in cancer risk.
