Objectives:
To investigate albumin (ALB) gene variations in patients suspected from familial dysalbuminemic hyperthyroxinemia (FDH).
Methods:
Eight Turkish patients were included into the study. Clinical and laboratory characteristics of the subjects and their parents were evaluated and genetic analysis were performed.
Results:
In genetic analysis, a previously reported heterozygous, c.725G>A variant was detected in exon seven of the ALB gene.
Conclusions:
FDH is an asymptomatic condition however there is still a risk of misdiagnosis and unnecessary treatment. Therefore, if FDH is considered, initial ALB hotspot sequencing as a rapid and simple method is recommended instead of complex and expensive laboratory and imaging techniques.

01:31Translation
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.

02:41Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

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...
