The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child. There are over 6,000 known genetic disorders in humans.
When the chromosome's structure is altered, this can take several forms: [16] Deletions: A portion of the chromosome is missing or has been deleted. Known disorders in humans include Wolf–Hirschhorn syndrome, which is caused by partial deletion of the short arm of chromosome 4; and Jacobsen syndrome, also called the terminal 11q deletion ...
A genetic disorder is a health problem caused by one or more abnormalities in the genome.It can be caused by a mutation in a single gene (monogenic) or multiple genes (polygenic) or by a chromosome abnormality.
This category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision. Generally, diseases outlined within the ICD-10 codes Q90-Q99 within Chapter XVII: Congenital malformations, deformations and chromosomal abnormalities should be included in this category.
Advanced sleep phase disorder; Aerotoxic syndrome; Afferent loop syndrome; Aicardi syndrome; ... Ring chromosome 20 syndrome; Roberts syndrome; Robinow syndrome;
Sex chromosome anomalies belong to a group of genetic conditions that are caused or affected by the loss, damage or addition of one or both sex chromosomes (also called gonosomes). In humans this may refer to: 45, X, also known as Turner syndrome; 45,X/46,XY mosaicism, also known as X0/XY mosaicism and mixed gonadal dysgenesis; 46, XX/XY
With an incidence of 1 in 15,000 to 1 in 50,000 live births, it is suggested to be one of the most common contiguous gene deletion disorders. 5p deletions are most common de novo occurrences, which are paternal in origin in 80–90% of cases, possibly arising from chromosome breakage during gamete formation in males [citation needed]
Chromosome instability syndromes include several inherited neurodegenerative diseases that are due to mutations in genes that encode enzymes necessary for DNA repair. Epigenetic alterations often occur in association with the DNA repair defect, and such alterations likely have a role in the etiology of the disease. Chromosome instability ...
