## Abstract Fragile X syndrome (FRAXA) is the most common form of inherited mental retardation (MR). The mutational mechanism leading to the disease involves an expansion of a trinucleotide repeat located at the 5โฒ UTR region of the gene __FMRโ1__. Four types of alleles can be identified in the pop

โฆ Synopsis
A family is described in which six females in three generations experienced premature ovarian failure (POF). In three of them a FRAXA premutation was documented and the carrier status of a fourth female could be inferred, because her son had the fragile X syndrome. These findings provide further evidence for a nonrandom association between POF and the FRAXA premutation.

## Abstract Since only 20% of female fragile X premutation carriers develop premature ovarian failure (POF, i.e., amenorrhea before age of 40 years), and since X chromosome inactivation (XCI) determines the phenotypic severity of full mutation women, we reasoned that the development of POF in fragi
Early menopause in the fragile X carriers has been well documented in several reports. All surveys demonstrated that 13-25% of fragile X carriers experienced premature ovarian failure (POF), defined as menopause before the age of 40 years. In 1995 we started screening two groups of subjects as a par
