Gene Defect Causes Abnormal Brain Size
Mutations in the gene ZNRF3 can lead to abnormal brain sizesβeither too large or too smallβcausing various neurological symptoms. This gene, known for its role in cancer, is crucial in regulating brain cell production. The study found that specific mutations in the gene disrupt the balance of brain cell development, with potential implications for cancer risk in patients with abnormally large brains.
