Clinical Report: Genetic Immunity Disorders in Low German Mennonite Populations

Background

Inborn errors of immunity (IEI) are genetic disorders that lead to immune dysfunction, increasing susceptibility to infections and other health issues. The Low German Mennonite (LGM) community in Mexico is characterized by genetic isolation and a high prevalence of autosomal recessive conditions, making it a significant population for studying IEI.

Data Highlights

Key Findings

• Four patients with distinct inborn errors of immunity (IEI) were identified in LGM communities in Mexico.
• Conditions included G6PC3 deficiency, X-linked agammaglobulinemia, and severe combined immunodeficiency (SCID).
• All patients required disease-specific therapies, including granulocyte colony-stimulating factor, immunoglobulin replacement, and hematopoietic cell transplantation.
• Genetic isolation in LGM communities contributes to the prevalence of rare autosomal recessive conditions.

Clinical Implications

Early diagnosis of inborn errors of immunity through newborn screening and accessible genetic testing is essential for improving patient outcomes in high-risk populations. Clinicians should consider the genetic background of patients from isolated communities when evaluating for IEI.

Conclusion

This case series enhances the understanding of inborn errors of immunity in Low German Mennonite populations and underscores the need for further research to validate these findings in larger cohorts.
