aspergers syndrome
Down syndrome mainly affects the persons physical features but it also affects their learning abilities.
Fragile X syndrome, is a genetic syndrome which results in a spectrum of characteristic physical, intellectual, emotional and behavioral features which include an elongated face, large or protruding ears, flat feet,
Practically every genetic disorder that includes physical characteristics affects facial features. The term is dysmorphic facial features genetic disorders.
DiGeorge syndrome may present with physical features such as heart defects, cleft palate, facial differences including a small chin or low-set ears, and various immune system abnormalities. Other features may include developmental delays and learning difficulties.
Individuals with Down syndrome often have a larger gap between their toes, known as a "sandal gap." This physical characteristic is significant because it can help doctors diagnose Down syndrome at birth or during prenatal screenings. The presence of a sandal gap is one of the physical features commonly associated with Down syndrome.
Turner syndrome is a genetic disorder caused by a missing or incomplete X chromosome in females. It is characterized by specific physical features and can lead to health issues such as short stature and infertility.
Vanishing twin syndrome was first recognized in 1945. Vanishing twin syndrome is when one of a set of twin/multiple fetuses disappears in the uterus during pregnancy. This is the result of a miscarriage of one twin/multiple. The fetal tissue is absorbed by the other twin/multiple, placenta or the mother. This gives the appearance of a "vanishing twin." http://www.americanpregnancy.org/multiples/vanishingtwin.html
Possible multiple and if none seen on ultrasound you could possibly have vanishing twin syndrome.
That is what they call "vanishing twin" or "fetal resorption." Sometimes it is not fully absorbed, but flattened, and the condition is called fetus papyraceus. If this happens in the first trimester, there may be no other complications except some bleeding. However, if it happens later, it could threaten the health of the mother or surviving twin. If it happens at the very end, and the dead fetus is low-lying, then a caesarean may be required to deliver the living twin.
Down syndrome is a genetic abnormality caused by the presence of an extra copy of chromosome 21. People with Down syndrome often have characteristic facial features, cognitive impairment, and may also have physical abnormalities, such as heart valve disease.
Male and female children are equally affected, and the syndrome occurs in all races and ethnic groups. Females with this syndrome have a better chance of surviving past infancy than males.
