What is C-peptide and Why is it Important in MODY?

C-peptide is a byproduct of insulin production.Maturity-Onset Diabetes of the Young: Rapid Evidence ... When the pancreas produces insulin, it also releases an equal amount of C-peptide. Therefore, measuring C-peptide levels in the blood or urine provides an indirect but reliable way to assess endogenous insulin secretion. This is particularly significant in understanding mody diabetes c-peptide levels because MODY is a group of monogenic disorders caused by mutations in specific genes that affect pancreatic beta-cell function and insulin secretion.

In contrast to Type 1 Diabetes, where the immune system attacks and destroys insulin-producing beta cells, leading to very low or undetectable C-peptide levels, individuals with MODY typically retain some level of insulin production. This means their C-peptide levels can vary, but are often higher than those seen in T1D作者：B Haberkorn·2024·被引用次数：1—Initial laboratory tests revealed normal levels ofC-peptide, indicating sufficient endocrine pancreatic function. ... Considering her young age, .... The level of fasting C-peptide measured at the time of diabetes manifestation is a key parameter that clinicians use to differentiate MODY from autoimmune diabetes.作者：R Peixoto-Barbosa·2020·被引用次数：113—C-peptidehas been studied as a screening tool for HNF1A/4AMODY, specifically as post-prandial UCPCR, for the sake of methodological simplicity ... A fasting C-peptide level of less than 0.60 ng per mL (0Maturity-Onset Diabetes of the Young (MODY): What It Is.20 nmol per L) is generally associated with insulin deficiency, often seen in T1D. However, in MODY, even with elevated blood glucose, a detectable serum C-peptide can indicate residual insulin production.

Diagnostic Utility of C-peptide in Differentiating Diabetes Types

Research consistently highlights the utility of C-peptide in classifying diabetes. The C-peptide is a useful marker for distinguishing MODY patients from autoimmune T1 diabetes. Studies have shown that C-peptide and pancreatic autoantibodies are crucial biomarkers that can support clinical suspicion of T1D, aid in diagnosing atypical cases, and support the diagnosis of MODY.

Furthermore, the urinary C-peptide creatinine ratio (UCPCR) has emerged as a practical outpatient tool for discriminating between different types of diabetes.Genetic testing for monogenicdiabetes(R141 and R143) will only be performed on patients confirmed to havediabetesby laboratory blood glucose or HbA1c. For instance, a urinary C-peptide creatinine ratio can help differentiate HNF1α/HNF4α MODY (often with a ratio >0.2 nmol/mmol) from T1D. This non-invasive method offers a convenient way to assess beta-cell function.

Specific C-peptide Levels and MODY

While there isn't a single definitive C-peptide value for all MODY subtypes, certain trends are observedMaturity-onset diabetes of the young (MODY) - ScienceDirect.com. Some studies indicate that MODY patients may have lower C-peptide levels compared to individuals with T2D. For example, one study found lower fasting C-peptide levels in MODY-positive participants compared to a MODY-negative group (2.2 ± 1.4 vs 3.2 ± 2.Diabetes1 ng/mL).Identification of appropriate biochemical parameters and ... Another study reported lower C-peptide levels (1作者：D Geneş·2024·被引用次数：2—The levels of insulin andC-peptidedetected in some patients withMODYare so low that they resemble those observed in patients with T1DM; in addition patients ....4 vs 2.5 ng/mL) in a screened MODY population.

It's important to note that in some MODY patients, the insulin and C-peptide levels can become so low that they resemble those observed in patients with T1DM. This underscores the need for a comprehensive diagnostic approach that includes genetic testing, especially when the clinical presentation is ambiguous.

The Role of Genetic Testing and Other Biomarkers

While C-peptide testing is invaluable, it is often used in conjunction with other diagnostic tools. Genetic testing is considered the gold standard for diagnosing MODY, as it can detect the specific gene mutations responsible for the condition. This is crucial because MODY is a group of monogenic disorders, meaning each type is caused by a mutation in a single gene作者：J Urbanová·2018·被引用次数：33—In our opinion,level of fasting C-peptide measured at the time of diabetes manifestationis the most beneficial in discriminating MODY from type 1 diabetes if ....

Other biomarkers, such as pancreatic autoantibodies, are also used, particularly to rule out autoimmune forms of diabetes like T1D.

People withMODYstill make some insulin. Genetic tests: These tests can detect changes to your genes. They're the only definitive way to diagnose .... The C-peptide test, whether through blood or urine analysis, provides critical information about endogenous insulin production, helping clinicians differentiate MODY from other forms of diabetes and guiding appropriate treatment strategies. When considering a diagnosis of diabetes, particularly in younger individuals with a family history, exploring C-peptide levels and considering genetic testing are vital steps.
