Özet

Aim: In this study, the relationship between genetic analysis and exome sequencing and clinical and neuroimaging findings of four patients from the same family was investigated by analyzing a clinical and genetic (WES) database containing more than 3000 patients. Methods: We analyzed the WES data of approximately 3000 patients performed in our center in terms of NTNG2 biallelic mutations. In addition, MR imaging findings were investigated. Results: We found four patients with the same mutation in the NTNG2 gene, presenting with similar clinical and neuroimaging findings. As a result of filtering, the c242G>A variant was determined in the NTNG2 gene. In addition, mild to severe brain parenchymal volume loss and frontal and temporal lobe atrophy were seen in cases 1, 2, and 4 on axial T2-weighted MRI. c. Conclusion: The current study has similar phenotypic and genotypic features and is a very rare report showing NTNG2 mutation in this context. Existing clinical data are important in choosing NTNG2 gene-related neuropsychiatric disorders as a future treatment target.
