Brazilian researchers used exome sequencing to diagnose rare disorders, monogenic diabetes and T-cell abnormalities syndrome, in a young boy with overlapping conditions, demonstrating its effectiveness in diagnosing growth disorders.

A recent study conducted by Brazilian researchers presented the case of a young boy with a series of symptoms and overlapping conditions, making diagnosis difficult. By using exome sequencing to analyze the protein-coding region of the genome, researchers discovered genetic alterations in GCK and BCL11B, which led to the identification of rare disorders - monogenic diabetes and T-cell abnormalities syndrome. This groundbreaking discovery shows that genetic sequencing can be effective in diagnosing growth disorders, significantly impacting the patients' treatment decisions.
