Phocomelia is a congenital condition that involves malformations of human arms and legs which result in a flipper-like appendage. [1] [2] A prominent cause of phocomelia is the mother being prescribed the use of the drug thalidomide during pregnancy; however, the causes of most cases are to be determined. [2]
external causes during pregnancy (thus not inherited), e.g. via amniotic band syndrome; teratogenic drugs (e.g. thalidomide, which causes phocomelia) or environmental chemicals; ionizing radiation (nuclear weapons, radioiodine, radiation therapy) infections; metabolic imbalance
Hecht Scott syndrome (also known as fibular aplasia–tibial campomelia–oligosyndactyly [FATCO] syndrome) is a rare genetic disease that causes congenital limb formation. [ citation needed ] The main characterisation is the aplasia or hypoplasia of bones (mainly the fibula or tibia ) of the limb. [ 1 ]
Hemivertebrae are wedge-shaped vertebrae and therefore can cause an angle in the spine (such as kyphosis, scoliosis, and lordosis). Among the congenital vertebral anomalies, hemivertebrae are the most likely to cause neurologic problems. [5] The most common location is the midthoracic vertebrae, especially the eighth (T8). [6]
The exact causes of hyperemesis gravidarum are unknown. [3] Risk factors include the first pregnancy, multiple pregnancy , obesity, prior or family history of HG, and trophoblastic disorder . A December 2023 study published in Nature indicated a link between HG and abnormally high levels of the hormone GDF15 , as well as increased sensitivity ...
He explains that these mutations eventually cause a protein imbalance and water and salt in the body's cells to surface, "resulting in mucus becoming thick and sticky, and difficulty clearing ...
Roberts reported a disease that was characterized by phocomelia, cleft lip, cleft palate, and a protrusion of the intermaxillary region in three siblings of an Italian couple who were first cousins, which made Roberts syndrome acquisition more likely for their children due to the disease's autosomal recessive nature.
Charlie was born deaf with a genetic disorder called Usher syndrome that will eventually cause vision loss as well. "Ultimately it results in progressive hearing loss. In some kids, like in ...
