Abstract:
Inherited Protein S (PS) deficiency is an autosomal dominant thrombotic disorder. We encountered a case of inherited type I PS deficiency following a close examination for recurrent pregnancy loss and identified the mutation responsible; a novel splice donor site mutation in intron 13 of the PROS1 gene appeared to have caused a frameshift with premature termination at amino acid +551. These results will contribute to the creation of an accurate database and define the molecular basis for PS deficiency.

Alternative RNA Splicing
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

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.

Cystic Fibrosis: Pathogenesis
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
