Meckel-Gruber Syndrome Meckel-Gruber Syndrome is a Fatal congenital autosomal recessive disease which is named after the German anatomist Johann Friedrich Meckel and the German physician Georg Gruber. This illness infects 1 in 13,250 to 1 in 140,000 people around the world; however, it’s more common in some regions. For instance, it was reported that Meckel syndrome has an incidence of 1 per 3,500 live births with a carrier rate of 1 in 30 in Bedouins in Kuwait (Teebi et al.1992). This…

Skewfoot is the name given to a congenital birth defect during the formation and growth of bones in the foot of the baby. It is also known by the name of Z foot or Serpentine Foot. It is also considered to an acute form of a foot deformity called as Metatarsus Adductus. In this deformity, the baby's foot has a "C" shaped appearance to it. Specially made shoes and rigorous stretching exercises are done until the child is big enough to ambulate, although it may not be good enough to correct the…

have an additional chromosome while some don’t this is known as mosaicism. The Mosaic trisomy 21 takes place when the error in the cell division happens early in development though it is after the sperm and the normal egg unite. This can also take place in early development when there are some cells who lose an extra chromosome 21 which was present at conception. Symptoms for this form vary between the Trisomy 21 but this depends on the amount of cells which have an extra chromosome.…

present. In some cases, however, there is bone structure within the digits making them partially or fully functional. According to Paul Arnold, polydactyly is caused by the mutation of a gene on chromosome 7. There are multiple mutations that can occur to a gene that is on the short arm of this chromosome resulting in extra digits on various parts of the feet or hands. This gene is the GLI3. This gene takes part in creating the patterns of organs and tissues while…

Cell division occurs rapidly in growing bulbs, sprouting seeds, and growing root tips. The reason that onion root tips are most commonly used to study mitosis. Onion root tip cell possesses eight chromosomes, whereas a human has 46 chromosomes. Another factor is that the stages can easily observe, and onion root tip can be flattened. The roots continue to increase as the roots search for water and nutrients. Regions of growth are good for studying because given time…

weaken the musculoskeletal system. Muscle Dystrophies are characterized by muscle weakness, defects in muscle proteins and the death of muscle cells and tissue. Duchenne Muscular Dystrophy is one of many types found and it passed down through the X chromosome. DMD is one of the most common muscle diseases found in early childhood. 1 in 3500 boys are born with DMD however very rarely affects girls with a 1 in 50million chance. It is caused by a small mutation in the DMD gene and it is inherited…

same number of chromosomes. Mitosis has interphase, prophase, metaphase, anaphase, and telophase. In interphase, the chromosomes have already been replicated. In interphase, chromosomes duplicate. During prophase, spindle fibers attach at each centromere. In metaphase, the chromosomes line…

daughter cells. Meiosis and mitosis are more complicated processes of cell division. Mitosis is part of the process used when a cell replicates itself, in its exact form. The cell duplicates perfectly, with the same DNA. During this phase, the chromosomes align, separate, and are moved to the opposite ends of the cell, forming two identical cells (OpenStax, 2013). Within this phase, there are five sub-phases called prophase, prometaphase, metaphase, anaphase, and telophase. An example of…

Turner’s syndrome is a condition that results in a person only being born with one X chromosome. This condition is due to when someone is born with only one sex chromosome. Those who have Turner’s syndrome have one X-chromosome and are missing the other sex chromosome. Because there is the presence of an X chromosome only those with Turner’s syndrome are consider having the sex of female. This syndrome results in a vast variety of medical issues, but most issues that those who have this syndrome…

Tay-Sachs Disease What if I told you that there was a disease that could cause your muscles to weaken. That it could also cause your brothers or sisters to die at an early age. Tay-Sachs Disease is a genetic disorder that usually happens in infants and the symptoms don’t show until the 5-6 months. This disease kills thousands if not hundreds of thousands. Tay-Sachs Disease symptoms are diagnosed according to what causes Tay-Sachs. Tay-Sachs is not inherited. Doctors, after diagnosis, will…
