Fragile X syndrome (FXS) is a genetic neurodevelopmental disorder characterized by mild-to-moderate intellectual disability. [1] The average IQ in males with FXS is under 55, while about two thirds of affected females are intellectually disabled.
While initially described as affecting male carriers, female carriers of the FMR1 gene mutation have also been found to develop FXTAS. However, due to X-inactivation, female carriers are much less likely to develop dementia or classic ataxia and tremor, instead demonstrating symptoms such as fibromyalgia, thyroid disease, hypertension, and ...
Fragile X-associated primary ovarian insufficiency (FXPOI) is the most common genetic cause of premature ovarian failure in women with a normal karyotype 46,XX. [1] The expansion of a CGG repeat in the 5' untranslated region of the FMR1 gene from the normal range of 5-45 repeats to the premutation range of 55-199 CGGs leads to risk of FXPOI for ovary-bearing individuals.

Genetic factors, such as fragile x syndrome. Approximately 20–28% of women with an FMR1 premutation (55–200 CGG repeats) experience fragile x primary ovarian insufficiency (POI) and another 23% experience early menopause (i.e., menopause before the age of forty five). [9] Autoimmune disorders. Adrenal gland impairment.
The zygotes merge early enough that there is no risk of them developing into conjoined twins. [14] Variations of this mechanism include fertilization of an ovum and its first or second polar body by two sperm. [15] 46,XX/46,XY can also be explained by a mosaic-based mechanism. A single zygote is formed from the fertilization of a normal X ovum.
Pregnancy Symptoms Week 1. It's a bit of a mind-bender, but you aren't actually pregnant during what doctors call "week one" of pregnancy. Instead, week one starts on the first day of your last ...
