Error in the number of chromosomes (too many or too few) includes the following disorders: Down’s syndrome or trisomy 21: The individual has an extra chromosome 21. When the chromosome's structure is altered, this can take several forms: This is because there are three copies of chromosome number 21 instead of the usual two. Numerical disorders occur when there is a change in the number of chromosomes (more or fewer than 46). Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the disabilities to be created within the child. He Patau's syndrome Is the third most common autosomal trisomy after Down syndrome and Edwards syndrome. Some of the most common chromosomal abnormalities include: Down's syndrome or trisomy 21; Edward's syndrome or trisomy 18; Patau syndrome or trisomy 13 However, the following words by Richard Dawkins seem to provide a great inspiration in understanding these diseases, and finding a way to counterbalance their errors.

Chromosomal abnormalities are changes to the number or structure of chromosomes that can lead to birth defects or other health disorders. An X-linked dominant disorder arises when a single copy of the gene leads to expression of the abnormal protein. Chromosome instability syndromes are a group of disorders characterized by chromosomal instability and breakage. Given below is a list of several genetic diseases and disorders, categorized on the basis of their inheritance and genetic complexity. An example of a chromosomal genetic disorder is Down syndrome. They may arise due to spontaneous mutations or may be inherited from the parents. Down syndrome is a … These mitochondrial genes are responsible for certain vital components of the cellular processes. As the name suggests, this set of genetic disorders refers to those arising due to mutations in a single gene. For example, Down syndrome is a chromosome disorder caused by the presence of an extra copy of chromosome 21, and Turner syndrome is most often due to the presence of only a single sex chromosome: one X chromosome. This set of diseases are manifested only when two copies of the mutated gene are inherited. Now they go by the name of genes, and we are their survival machines.”– Richard Dawkins. Based on the location and the inheritance pattern of the gene, these diseases are further classified into the following types. Slight alterations to genes on the chromosomes may produce new traits such as bigger claws that may be beneficial to survival. The inheritance of these disease is often complex and depends on several factors. Chromosome disorders can be classified into two main types; numerical and structural. If one gene is defective whereas the other inherited gene is normal, the individual is simply a carrier of the gene, and does not suffer from the disease. Description: Wolf-Hirschhorn syndrome is caused by the deletion of the distal short arm of chromosome 4. Unfortunately, the list of genetic diseases is an unending one, and new additions occur frequently, thereby presenting a new challenge to researchers and the medical community.

The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Apart from these two types, chromosomal disorders are the third type of genetic disorder which occurs due to the changes in the chromosomal numbers and the structure. Chromosomes are thread-shaped structures that are found in cells of living organisms and that contain DNA, a nucleic acid that contains the genetic instructions for those organisms.A chromosome disorder can be caused by an alteration in the number of chromosomes in a cell's nucleus or by an alteration in the structure of a chromosome. Chromosomal disorders result from structural changes or numerical changes in chromosomes. Examples of chromosomal disorders. A List of Inherited Genetic Diseases Learn More Neimann-Pick disease is actually a group of inherited disorders that involve the metabolic system, where large amounts of fatty material, or lipids, start to accumulate on organs like the liver, spleen, lungs and brain, according to the National Institute of Neurological Disorders and Stroke (NINDS). In the case of this syndrome the genetic anomaly specifically affects the chromosome 13, that is to say that it has three copies of the same chromosome. The susceptibility to these diseases with respect to the different factors has been illustrated below. Each human cell contains 46 (2n) chromosomes present as 23 pairs (n pairs), out of which 22 are autosomes and 1 pair of sex chromosomes. These units of heredity are arranged together, along with their regulatory sequences, to form chromosomes. The National Perinatal Statistics Unit last reported on congenital anomalies in Australia in 2002–03 (Abeywardana & Sullivan 2008). Main clinical disorders [edit | edit source] The gain or loss of chromosome material can lead to a variety of genetic disorders. Probably one of the most well-known numerical disorders is Down syndrome (trisomy 21). Chromosomal disorders are a result of an alteration in genetic material.

There are many different types of chromosome abnormalities that require clinical care by a physician or other healthcare professional. Listed in the directory below … Diseases that are characterized by alterations in mitochondrial function due to defects in nuclear or mitochondrial DNA (mtDNA) are collectively called mitochondrial diseases. 49.1 Chromosomal anomalies in Australia. Cytogenetic evaluation is an important step in the diagnosis of infertile or sterile animals. One of the most common examples of a genetic condition caused because of an extra chromosome is Down syndrome. Phenotypes associated with sex chromosome disorders are less severe than autosomal defects and this is mainly due to X chromosome inactivation, as well as the fact that Y chromosomes have a low gene content. The diseases resulting due to defects or anomalies in genes present on the Y chromosome are termed Y-linked disorders. Genetic diseases that arise due to defects in more than one gene as well as non-genetic factors are termed polygenic or multifactorial genetic diseases. An overactive immune system has as much potential for inducing health hazards as an under active immune system. The two known examples of Y-linked disorders are: This subset include diseases that are associated with several genes but result due to mutation in any of them. The non-genetic factors include environment, lifestyle, diet, habits, etc. In this set of disorders, a single copy of defective gene located on the X-chromosome results in the manifestation of symptoms.
