Maroteaux–Lamy syndrome, or Mucopolysaccharidosis Type VI (MPS-VI), is an inherited disease caused by a deficiency in the enzyme arylsulfatase B (ARSB). [3] ASRB is responsible for the breakdown of large sugar molecules called glycosaminoglycans (GAGs, also known as mucopolysaccharides).
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.
Cri du chat syndrome is a rare genetic disorder due to a partial chromosome deletion on chromosome 5. [1] Its name is a French term ("cat-cry" or "call of the cat") referring to the characteristic cat-like cry of affected children. [2] It was first described by Jérôme Lejeune in 1963. [3]
Spinal muscular atrophy is a genetic condition set in motion before birth that causes worsening muscle weakness. There are four types of the disorder, each with varying degrees of severity.
Most genetic disorders are rare in themselves. [5] [8] Genetic disorders are present before birth, and some genetic disorders produce birth defects, but birth defects can also be developmental rather than hereditary. The opposite of a hereditary disease is an acquired disease.
Norrie disease is a rare genetic disorder caused by mutations in the NDP gene, located on Xp11.4 (GeneID: 4693). [22] It is inherited in an X-linked recessive manner. This means that almost only males are affected. Sons of affected men will not have the mutation, while all of their daughters will be genetic carriers of the mutation. Female ...
Noonan syndrome (NS) is a genetic disorder that may present with mildly unusual facial features, short height, congenital heart disease, bleeding problems, and skeletal malformations. [1] Facial features include widely spaced eyes , light-colored eyes, low-set ears , a short neck, and a small lower jaw . [ 1 ]
Anodontia typically occurs with the presence of ectodermal dysplasia, which is a group of disorders where two or more ectodermally derived structures will have abnormal development. In the rare case that ectodermal dysplasia is not associated or present, anodontia will be caused by an unknown genetic mutation.
