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.
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.
Orphan drugs are medications targeting orphan diseases. Most rare diseases are genetic in origin and thus are present throughout the person's entire life, even if symptoms do not immediately appear. Many rare diseases appear early in life, and about 30% of children with rare diseases will die before reaching their fifth birthdays. [1]
Weaver syndrome is an extremely rare autosomal dominant genetic disorder associated with rapid growth beginning in the prenatal period and continuing through the toddler and youth years. It is characterized by advanced osseous maturation and distinctive craniofacial, skeletal and neurological abnormalities. [ 1 ]
CHARGE syndrome (formerly known as CHARGE association) is a rare syndrome caused by a genetic disorder.First described in 1979, the acronym "CHARGE" came into use for newborn children with the congenital features of coloboma of the eye, heart defects, atresia of the nasal choanae, restricted growth or development, genital or urinary abnormalities, and ear abnormalities and deafness.

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 ...
They come in all shapes and sizes. Some walk, some slither, some fly and some swim. Humans are blessed to share the planet with just over 2.1 million recognized species of animals. And scientists ...
The diagnosis is confirmed through genetic testing. Physicians will obtain a blood or saliva sample for genetic testing which looks for a deletion within the NSD1 gene or a heterozygous pathogenic variant of the gene. [10] If there is clinical suspicion of Sotos syndrome in a fetus, physicians may perform genetic testing on the fetus. [14]
