![]() Mosaic Turner syndrome, also called mosaicism or Turner mosaicism: During the early stages of fetal development, an error may occur in cell division, resulting in some cells having two X chromosome copies, while others only have one. Every cell in the offspring’s body has one X chromosome missing. Experts believe this is caused by an error either in the father’s sperm or the mother’s egg. Monosomy: One X chromosome is completely missing. When a female has TS, one X chromosome copy is either absent or significantly altered.Ī number of genetic alterations are possible in TS. Females inherit one X chromosome from each parent. Males inherit the X chromosome from their mothers and the Y chromosome from their fathers. ![]() Most people are born with two sex chromosomes. a fourth finger or toe that is shorter than normal. ![]() diabetes is more likely in older and overweight females with TS than in other women with similar weight and age.hearing loss in adulthood may be due to otitis media during childhood.otitis media, middle ear infection, or glue ear, is common among young girls with TS.osteoporosis, or brittle bones, due to insufficient estrogen.hypothyroidism, or an underactive thyroid gland, treatable with thyroxine tablets.narrowing of the aorta, which may result in a heart murmur.mouth abnormalities that can cause dental problems.Other possible signs and symptoms include: Most girls with TS will not produce these sex hormones.Īlthough a female with TS has non-functioning ovaries and is infertile, her vagina and uterus, or womb, is usually normal, and most females with TS will be able to have a normal sex life.Īround 20 percent of females with TS will start menstruating during puberty, but it is rare for a woman with TS to become pregnant without fertility treatment. Normally, during puberty, a female’s ovaries start producing the sex hormones, estrogen, and progesterone. Social problems include difficulty interpreting other people’s reactions or emotions. Most girls with TS have normal intelligence and good verbal and reading skills, but some may have problems with math, spatial concepts, memory skills, and fine finger movements. Short stature: An adult female may be about 8 inches, or 20 centimeters, shorter than expected for an adult female member of that family, unless they have treatment.During the first 3 years of life, the infant may have normal height, but by the age of 3 years, their growth rate will be lower than average, and by the age of 5 years, short stature will be noticeable. Irregular growth: Growth spurts may not occur at expected childhood times.In some cases, TS may not become apparent until later on. wide neck with extra folds of skin, sometimes described as “web-like”.a high, narrow palate, or roof of the mouth.cubitus valgus, where arms turn outwards at the elbows.a broad chest with widely-spaced nipples.cystic hygroma, or swelling of the neckĪt birth or during infancy, there may be:. ![]() Newborns with TS may have swollen hands and feet. Lymphedema happens when fluid is not properly transported around the organs of the fetal body, and excess fluid leaks into the surrounding tissue, resulting in swelling. Signs and symptoms before birth include lymphedema. The signs and symptoms of Turner syndrome vary considerably. Mosaic Turner syndrome, mosaicism, or Turner mosaicism is where the abnormalities occur only in the X chromosome of some of the body’s cells.This affects about half of all people with TS. In classical Turner syndrome, an X chromosome is completely missing.Chromosomes contain instructions that make a human’s behavioral and physical characteristics. Life expectancy is slightly lower than it would be for most people.Ĭhromosomes are strands of deoxyribonucleic acid (DNA) that exist in all the cells of the human body. In the United States, around 70,000 women are thought to have TS. Sometimes the whole chromosome will be absent.Īround 1 in 2,500 girls is born with the condition, but it probably affects more pregnancies that do not survive to term. However, individuals with Turner syndrome do not have part of a second sex chromosome. People without Turner syndrome have 46 chromosomes, of which two are sex chromosomes.
