Abstract:
Lacrimo-auriculo-dento-digital syndrome (LADD syndrome), also known as Levy-Hollister syndrome, is an autosomal dominant defect with variability on phenotypical expression. This syndrome is characterised by the association of dysplasia in various organs and systems that affect craniofacial structures, including lachrymal and salivary glands, teeth, internal and external ear, and the bone skeleton. We present this unusual and almost unknown syndrome (the first case in our state, with only about 100 cases described in the world, distributed in a few families) in a teenager of 17 years admitted to PICU for another reason. After the physical examination, a clinical diagnosis was made in the entire family branch.

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, but...

Lethal 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...
