Abstract:
There have been several reports on 5q31.3 microdeletion syndrome. The overlapping deleted region includes purine-rich element binding protein A (PURA), which encodes transcriptional activator protein Pur-α. Patients with PURA mutations show moderate to severe neurodevelopmental delay and learning disability. Neonatal hypotonia, respiratory insufficiency, feeding difficulties, and seizures are often seen. Dysmorphic features including myopathic faces are helpful as clinical signs of the diagnosis. We report a patient with a novel PURA mutation detected by whole-exome sequencing. We suggest that PURA abnormality is a recognizable syndrome.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

Allosteric Proteins-ATCase
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis...
