Increased knowledge of genomics over the past two decades has made it apparent that the traditional category of genetic diseases represents only those conditions in which the genetic contribution is particularly marked, whereas in fact diseases can be arrayed along a spectrum representing the varied contribution of genes and the environment. (who.int)
However, this report focuses on the traditional category of genetic diseases and associated congenital malformations , both of which conditions are manifested early in life and for which clinical interventions are available. (who.int)
These conditions are described as genetic diseases because a defect in one or more genes or chromosomes leads to a pathological condition. (who.int)
Multifactorial disorders, on the other hand, where genetic and environmental factors interact, have not traditionally been considered to be genetic diseases. (who.int)
Multifactorial disorders are usually categorized as congenital malformations , such as neural tube defect, cleft lip and palate, or diseases with a genetic predisposition , such as some chronic, noncommunicable diseases. (who.int)
In the literature, congenital malformations are often associated with genetic diseases because they both tend to present during pregnancy, at birth or in early childhood. (who.int)
Some genetic diseases, such as haemophilia, are carried on the X-chromosome (these X-linked disorders occur mainly in men). (who.int)
Others can arise from the presence of an abnormal gene in any autosome: if the gene is dominant, it results always in what is called a dominant condition, whereas if it is recessive many of these diseases appear only when the gene is inherited from both parents (and are thus called recessive conditions). (who.int)
All people are at risk of diseases due to genetic mutations. (who.int)
The higher prevalence of genetic diseases in particular communities may, however, be due to some social or cultural factors. (who.int)

Genes consist of deoxyribonucleic acid (DNA). (msdmanuals.com)

A trait is any gene-determined characteristic and is often determined by more than one gene. (msdmanuals.com)

May have trisomy of other chromosomes, eg. (mindmeister.com)

is a circular structure that occurs when a chromosome breaks in two places and its broken ends fuse together. (medlineplus.gov)

Pyramiding of alien-derived Wheat streak mosaic virus (WSMV) resistance and resistance enhancing genes in wheat is a cost-effective and environmentally safe strategy for disease control. (nature.com)
The dissemination of antibiotic resistance in Aeromonas is predominantly facilitated by chromosome -borne accessory genetic elements , although the existing literature on this subject remains limited. (bvsalud.org)
Moreover, the study aims to uncover novel genetic environments associated with antibiotic resistance on these elements . (bvsalud.org)
Several novel antibiotic resistance genetic environments were uncovered in these elements . (bvsalud.org)

The date of the emergence of these genetic changes therefore must be older than that estimated with only extant human diversity data, thus demonstrating the utility of direct evidence from Neandertal DNA sequences for understanding recent modern human evolution. (sciencedaily.com)

Genes vary in size, depending on the sizes of the proteins or RNA for which they code. (msdmanuals.com)

In general "we may regard supernumeraries as a very special category of genetic polymorphism which, because of manifold types of accumulation mechanisms, does not obey the ordinary Mendelian laws of inheritance. (wikipedia.org)

Epilepsy is a common feature of ring chromosome syndromes, including ring chromosome 14. (medlineplus.gov)
