                                Serine deficiency disorders are a group of rare neurometabolic diseases caused by defects in the biosynthesis of the amino acid L-serine. The most significant symptoms of a low serine level are neurological and can appear from infancy to adulthood, emphasizing the amino acid's critical role in brain development and function.
