Abstract:
Acrodermatitis enteropathica (AE) is a rare disease that results from a defective gene, SLC39A4, and is characterized by dermatitis, alopecia, and diarrhea. We report a case of AE presenting with only periorificial and acral dermatitis in which genetic testing revealed two novel compound heterozygous missense mutations for SLC39A4. This case demonstrates that not all AE mutations alter zinc transporters in the same manner and highlights the phenotypic variability of AE.

Smooth Endoplasmic Reticulum
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...
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.
