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.
Severe combined immunodeficiency (SCID), also known as Swiss-type agammaglobulinemia, is a rare genetic disorder characterized by the disturbed development of functional T cells and B cells caused by numerous genetic mutations that result in differing clinical presentations. [2]
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]
Roberts syndrome, or sometimes called pseudothalidomide syndrome, is an extremely rare autosomal recessive genetic disorder that is characterized by mild to severe prenatal retardation or disruption of cell division, leading to malformation of the bones in the skull, face, arms, and legs.
Hutchinson-Gilford progeroid syndrome (HGPS) is an extremely rare autosomal dominant genetic disorder in which symptoms resembling aspects of aging are manifested at an early age. [8] Its occurrence is usually the result of a sporadic germline mutation ; although HGPS is genetically dominant, people rarely live long enough to have children ...
Smith-Kingsmore syndrome is a rare genetic disorder that is caused by gain-of-function mutation in a gene MTOR.The facial features of this syndrome are triangular face with a pointed chin, frontal bossing, hypertelorism, eyes with downslanting palpebral fissures, a flat nasal bridge, a long philtrum.
However, while XLA is a congenital disorder, with known genetic causes, CVID may occur in adulthood and its causes are not yet understood. In addition, to X-linked agammaglobulinemia a couple of autosomal recessive agammaglobulinemia gene mutations have been described including mutations in IGHM, [ 10 ] IGLL1, [ 11 ] CD79A/B, [ 12 ] [ 13 ] BLNK ...
CDK13-related disorder, also known as congenital heart defects, dysmorphic facial features and intellectual developmental disorder (CHDFIDD), is a very rare autosomal dominant genetic condition characterised by congenital heart defects, intellectual disability and characteristic facial features.
