Abstract:
A neonatal boy presented with a persistent urticarial rash. Initial investigations showed raised inflammatory markers and evidence of systemic inflammation. A working diagnosis of cryopyrin-associated periodic syndrome (CAPS) was made, and the patient responded extremely well to Anakinra. Molecular genetic testing revealed a somatic mutation (affecting 12.5% of cells) in the NLRP3 gene, accounting for the persistent inflammatory state but milder phenotype as seen in our patient.

pre-mRNA Processing
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...
The Proteasome
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. A series of enzymes carry out the ubiquitination of the target proteins - E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...
