The Noonan Syndrome Characteristics You Must Know

Noonan Syndrome is a genetic disorder that impedes normal development in various parts of the body. A child can be stricken with Noonan syndrome in a variety of ways: unusual facial characteristics, short stature heart defect, other physical problems, and sometimes mental retardation.

Noonan syndrome is caused by a genetic mutation and are obtained when a child inherits a copy of the affected genes from the parents. It can also occur as a spontaneous mutation in children, which means there is no family history involved.

The characteristics of children with Noonan Syndrome, among others:

1. Characteristics of the face

-Early childhood. An infant with age less than 1 month seems lowly ears, short neck and at the back of the head low hairline
-Childhood. Children have eyes stand out with the slope down and the nose is wide and round. Often seen the lack of facial expression.
-Teens. At adolescence, her face is wide, usually the facial features become sharper and less prominent eyes, elongated neck
-Adult. When a child with Noonan syndrome reaches adulthood, the skin wrinkles and visibly transparent.

2. Growth issues

Your child's birth weight will probably be normal, but some children with Noonan syndrome have trouble with eating. This can lead to poor weight gain to about 18 months.

The acceleration of growth that typically seen during adolescence may be delayed in your child, but because the disease causes the bone maturity will be delayed, your child has the potential to continue to grow into her late teens.

By adulthood, about one-third of people with the syndrome Noonan has normal height, but short stature remain more common.

3. Abnormalities of the heart

More than half of sufferers of the syndrome suffer from congenital heart disease, with the following disorders:

Pulmonary valve stenosis. This is the most common heart problems occur in the case of noonan syndrome. Narrowing of the pulmonary valve that carries blood from the heart to the lungs
Hypertrophic cardiomyopathy. An abnormal growth or thickening of the heart muscle
Structural defects. A person with the syndrome has structural damage at its heart. The damage can be either ventricular septal defects or pulmonary artery stenosis

What is Three Parts of Nucleotide ?

What is Three Parts of Nucleotide ? Nucleotides are biological molecules that form the building blocks of nucleic acids (DNA and RNA) and serve to carry packets of energy within the cell (ATP). In the form of the nucleoside triphosphates (ATP, GTP, CTP and UTP), nucleotides play central roles in metabolism. In addition, nucleotides participate in cell signaling (cGMP and cAMP), and are incorporated into important cofactors of enzymatic reactions (e.g. coenzyme A, FAD, FMN, NAD, and NADP+). A nucleotide is composed of a nucleobase (nitrogenous base), a five-carbon sugar (either ribose or 2-deoxyribose), and one or more phosphate groups. Three parts of nucleotide image That are three parts of nucleotide, Nucleotides can be synthesized by a variety of means both in vitro and in vivo. There a 4 different nucleotides ATP,GTP (purines) TTP,CTP (pyrimidines) which differ in the chemical structure of the base. They are generally referred by a single letter A, G...

Why Patau Syndrome or Known as Trisomy 13

Trisomy 13 or Patau Syndrome is the most severe viable trisomy caused by an additional copy of chromosome 13 that usually causes a host of developmental problems and physical deformities in a newborn. Patau syndrome is generally recognized at birth by the presence of structural birth defects and poor neurologic performance. Additional structural anomalies are common, particularly facial anomalies (midline clefts, hypotelorism, microphthalmia, and anophthalmia) arising from structural anomalies of the brain, frequently microcephaly and holoprosencephaly. Other associated anomalies include cardiac, renal, and intestinal (diaphragmatic hernia) anomalies. Characteristic features include low set ears, post-axial polydactyly, flexion contractures, rocker bottom feet, scalp defects, and haemangiomas. What is the cause of Patau Syndrome ? The exact incidence of Patau syndrome is not known, although it appears to affect females more than males, most likely because ...

How to DNA to Protein Translation Process

DNA to protein translation process - This one-way flow of information from DNA to protein is called the central dogma of molecular biology. Information stored in DNA is copied to RNA (transcription), which is used to assemble proteins (translation). Each DNA strand is composed of sub-units called nucleotides or, “bases” for short. There are four types of nucleotides – adenine, A; thymine, T; guanine, G and cytosine, C. An A always pairs with T, and G with C. Thus the two strands of DNA are complementary to each other. Nucleotides are arranged in a specific order on DNA – this is called the sequence of DNA. This sequence is further sectioned into genes – a short segment of DNA that is made into one polypeptide (protein) chain. Cells convert DNA to protein in a two-step process. Transcription: DNA to RNA Transcription occurs in the nucleus. Transcription in the process by which RNA is assembled from a DNA template. To transcribe a gene, th...
