What is the effect of a mutation in the Hox gene? Similarly, mutations in the Hox genes can result in body parts and limbs in the wrong place along the body. Like a play director, the Hox genes do not act in the play or participate in limb formation themselves. The protein product of each Hox gene is a transcription factor. Do mutations occur in Hox genes? Hox genes are found in many animals, including fruit flies, mice, and humans. Mutations in human Hox genes can cause genetic disorders. How do Hox genes affect development? The role of the Hox...

Which layer is hypertrophied in pyloric stenosis? Hypertrophic pyloric stenosis (HPS) is the most frequent surgical condition in infants in the first few months of life [1]. The condition is characterised by thickening of the muscular layer and failure of the pyloric canal to relax resulting in gastric outlet obstruction. Where do you palpate pyloric stenosis? With the infant supine and the examiner on the child's left side, gently palpate the liver edge near the xiphoid process. Then displace the liver superiorly; downward palpation should reveal the pyloric olive just on or to the right of the midline. Which outlet...
