Causes Of Triple X Syndrome
Normal: Life expectancy should be normal. There are no effects that affect heart, or other major systems that would reduce life expectancy.
Depends on symptoms: Trisomy X syndrome can range from mild to severe, the life style changes would depend upon its severity. Pl see attached link forother details about the condition from the Mayo clinic. Good luck!
Chromosome defect: Patients with fragile x have a defective x chromosome. There are several variants, and not all cells may be affected. It is full disease only in males, but females can be carriers. It is a genetic disorder, but it often just occurs without warning. Affected boys can vary from normal to severe retardation and autism. There is no cure.
Gene mutation: Fragile x syndrome is due to a mutation within the fmr1 gene on x chromosome. Part of the gene gets repeated too many times. It is the most common genetic cause of intellectual disability. Please see: http://www. Ncbi. Nlm. Nih. Gov/pubmedhealth/pmh0002633/ and http://www. Fragilex. Org/ for more information.
Genetic: Fragile x is caused by just one defective gene. This gene also known as fmr1, shuts it self down and fails to produce a protein. The incidence is 1 in 4000 males and 1 in 6-8000 females have it is the most common cause of inherited mental disability-.
Chromosomal defect: Klinefelter syndrome - a male with an extra x chromosome occurs when chromosomes fail to separate very early in development. So it is caused by a developmental issue and is not inherited. There is nothing that suggests a trisomy x woman is more likely to have a klinefelter child, but she has the same risk as other women. A geneticist can give you more information about potential risks.See 1 more doctor answer
Find experts in your: Area by using the nfxf contact form at www. Fragilex. Org/foundation/contact/. A local Developmental/Behavioral Pediatrician & your state's Early Interventon Program if the child is < 3 years old or your public school district if he's 3 or older can evaluate him/her for ASD, ADHD + cognitive, adaptive, motor & behavioral issues & team with you to develop an individualized treatment plan.
Normal: These women appear no different from any other and have no special problems.
Defective chromosome: Each person has 23 pair of chromosomes. Males have xy and females xx. Some persons have a defective x with a portion that is missing. In females the other x compensates and they have no clinical problems. In males the defective x can result in retardation and/or autism. Some with defect can be normal but transfer problems to their sons.
Not preventable: While there is no way to prevent fragile X disorder, treatment with folic acid, a vitamin can be helpful with the behaviours if necessary. Behavioral therapy, applied behavioral analysis, A variety of medications are available for symptoms. You should consult a specialist working with children with Fragile X.See 1 more doctor answer
Depends on your dfn: Significant impairment (iq<70) in FAS is felt to represent 1/3600 of the population, mostly male. A lesser form of involvement with lesser alterations in this gene (add, behavior issues) may affect 1/130-250 female & 1/250-800 males. See: www. Ncbi. Nlm. Nih. Gov/pmc/articles/pmc2888470/? Tool=pmcentrez.
Male dominated: The fragile x is named for a non staining region on the long arm of an x containing useless genetic material that results in mental impairment & physical changes (if you only have 1 x:males).The females usually show few if any features due to protection by a normal x, but not always & have a 50% chance of passing the fragile x to any offspring. This is a male dominated form of mental impairment.
