Achondroplasia

Achondroplasia is a form of short-limbed dwarfism. GENE: The FGFR3 gene makes a protein called fibroblast growth factor receptor 3. The function of the protein from the gene is involved in transforming cartilage into bone. FGFR3 is the only gene known to be related with achondroplasia. There is also a receptor called tyrosine kinase. It negatively regulates the growth plate activity and stright bone growth. All people who have only a single copy of the normal FGFR3 gene and a single copy of the FGFR3 gene mutation have achondroplasia. It can be inherited when one individual is less than the usual size and a normal sized individual produce a child. When achondroplasia is inherited, it is inherited in an autosomal dominant

A growth hormone is produced in the anterior pituitary gland and stimulates the bone and muscle growth needed for normal physical growth in children. In dwarfism, it produces too little growth hormone secretion. Achondroplasia is correlated with the endocrine system and it may be treated using hormonal therapy. If the cause is during the period of preceding puberty of growth hormone, supplemental growth hormone may be used to correct the abnormality. Hypothyroidism is also another possible cause of achondroplasia that can be treated through hormonal therapy. To treat it they can get injections of thyroid hormones to decrease the effects of the condition, but physical problems may be irreversible. Pain and disabilities can be improved by physical therapy, for example they will use braces, other orthotic devices, or by surgical procedures. Sleep apnea, which involves brief periods of slowed breathing or breathing that stops is common in people with achondroplasia. Symptoms of sleep apnea include snoring and sleeping with the neck in a hyperextended condition. To treat sleep apnea, they sometimes perform adenotonsillectomy, which is a surgery that removes the tonsils to open up the airway. They also use methods like weight loss, and nasal-mask for continuous positive airway pressure. They can also have decreased muscle tone, which can cause delays in walking and other motor skills. At infancy the legs are straight, but once they

    It is my belief that the growth may fall into the category of a neoplastic condition (White et. al 2012: 452). Though, it could easily be argued the growth is sort of infectious disease it is unlikely. Most infectious diseases live little trace of their presence on the skeletal structure. However, chronic diseases do, in fact, leave evidence on bone so it would not be impossible for the growth to be the result of something infectious (White et.…

    Achromatopsia is caused by a mutation in three genes: cyclic nucleotide gated channel beta 3 (CNGB3) gene, cyclic nucleotide gated channel alpha 3 (CNGA3), and GNAT2. (Sieveing) CNGB3 and CNGA3 genes code for the making of subunits in the cone photoreceptor cyclic nucleotide-gated (CNG) channel. (Sieving) These mutations impair cone function. (M3 Sieving).…

They learn many things from TV, but their social skills and other learning abilities slow down.…

    The average age to begin walking for a child with this genetic disorder is approximately eighteen months. When the sufferer is young, they can start showing small signs such as the following: falling, trouble walking/running, difficulty climbing stairs, and/or not having the ability to stand on their own very well. As these problems begin to worsen, they begin to weaken the pelvic muscle. The child walks on the balls of his or her feet and with the abdomen pushed forward. The muscles in the shoulders will also become weak as the child loses the ability to raise his or her arms (Abramovitz p. 19-21).…

    Osteochondrodysplasia is a group of unusual hereditary disorders of the bone, connective tissue, or cartilage. In this disorder growth and evolution of cartilage, bone, and connective tissue are impaired. Osteochondrodysplasias can be passed down by the parent to the offspring. This disorder causes the skeleton to flourish abnormally and the results can lead to dwarfism. The chances in someone having osteochondrodysplasia is one in every 4000 to 5000 births.…

    For a century, scientists studied chromosomes by looking at them under a microscope. In order for chromosomes to be seen this way, they need to be stained. Once stained, the chromosomes look like strings with light and dark bands, and their picture can be taken. A picture, or chromosome map, of all 46 chromosomes is called a karyotype. The karyotype can help identify abnormalities in the structure or the number of chromosomes.…

Once the type and severity of the disease is figured out, the team of caregivers formulate a plan of treating the patient and improving the patient’s quality of care. The first step for a diagnosis is a thorough physical examination by a doctor. Early and overall physical signs of MD will vary due to which specific dystrophy is present. The simplest early physical finding is generalized weakness that starts proximal and spreads distally.…

Acromegaly results in characteristic changes of connective tissues and its occurrences of acromegaly is about 6 in every 100,000 adults.
