Premature Ovarian Failure Genetic Aspects of Premature Ovarian Failure P. Wieacker Premature ovarian failure (POF) is characterized by the combination of amenorrhea before age 40 years and hypergonadotropic hypogonadism. The prevalence is approximately 1 %. Genetic causes of POF include chromosome aberrations and monogenic defects. Furthermore, polygenic-multifactorial inheritance can be assumed in a subset of cases. J Reproduktionsmed Endokrinol 2009; 6 (1): 17–8. Key words: premature ovarian failure, chromosome aberrations, gene mutations Introduction Premature ovarian failure (POF) is char- acterized by the onset of amenorrhea be- fore age 40 years combined with toni- cally increased levels of gonadotropins and hypoestrogenism (hypergonado- tropic hypogonadism, ovarian insuffi- ciency WHO group III). Premature ovar- ian failure affects approximately 1 % women by age 40, 1:1000 by age 30, and 1:10000 by age 20 [1]. POF is a heterogeneous disorder caused by non-genetic (infections, radiotherapy and chemotherapy) and genetic factors, including chromosome aberrations, mo- nogenic defects and polygenic-multifac- torial dispositions. Chromosome aberra- tions can be detected in approximately 9 % [2], including Triple X syndrome, Figure 1: Possible mechanisms of hypergonadotropic hypogonadism in females.

FSHβ-, FSHR- or LHR-mutations can cause such a condition.

E-mail: [email protected] This review presents the genetic disorders associated with premature ovarian failure (POF), obtained by Medline, the Cochrane Library and hand searches of pertinent references of English literature on POF and genetic determinants cited between the year 1966 and February 2002. X monosomy or X deletions and translocations are known to be responsible for POF. Turner's syndrome, as a phenotype associated with complete or partial monosomy X, is linked to ovarian failure. Among heterozygous carriers of the fragile X mutation, POF was noted as an unexpected phenotype in the early 1990s. Autosomal disorders such as mutations of the phosphomannomutase 2 (PMM2) gene, the galactose-1-phosphate uridyltransferase (GALT) gene, the FSH receptor (FSHR) gene, chromosome 3q containing the Blepharophimosis gene and the autoimmune regulator (AIRE) gene, responsible for polyendocrinopathy-candidiasis-ectodermal dystrophy, have been identi®ed in patients with POF. In conclusion, the relationship between genetic disorders and POF is clearly demonstrated in this review. Therefore, in the case of families affected by POF a thorough screening, including cytogenetic analysis, should be performed. Key words: autosomal disorders/FSH receptor/inhibin/premature ovarian failure/X chromosome abnormalities TABLE OF CONTENTS diagnosis requires histological examination of a full-thickness ovarian biopsy (Metha et al., 1992; Olivar, 1996).

In sex development we can distinguish two different processes¸ sex determination , that is the developmental decision that directs the undifferentiated embryo into a sexually dimorphic individual. In mammals, sex determination equals gonadal development. The second process known as sex differentiation takes place once the sex determination decision has been made through factors produced by the gonads that determine the development of the phenotypic sex.

ICD-9 758.0 OMIM 190685 DiseasesDB 3898 MedlinePlus 000997 eMedicine ped/615 MeSH [2] Down syndrome (the most common term in US English), Down's syndrome (standard in the rest of the English-speaking world), trisomy 21, or trisomy G is a chromosomal disorder caused by the presence of all or part of an extra 21st chromosome. It is named after John Langdon Down, the British doctor who described the syndrome in 1866. The disorder was identified as a chromosome 21 trisomy by Jérôme Lejeune in 1959. The condition is characterized by a combination of major and minor differences in structure. Often Down syndrome is associated with some impairment of cognitive ability and physical growth as well as facial appearance. Down syndrome in a baby can be identified with amniocentesis during pregnancy or at birth. Individuals with Down syndrome tend to have a lower than average cognitive ability, often ranging from mild to moderate developmental disabilities. A small number have severe to profound mental disability. The incidence of Down syndrome is estimated at 1 per 800 to 1,000 births, although these statistics are heavily influenced by older mothers. Other factors may also play a role. Many of the common physical features of Down syndrome may also appear in people with a standard set of chromosomes, including microgenia (an abnormally small chin)[1], an unusually round face, macroglossia [2] (protruding or oversized tongue), an almond shape to the eyes caused by an epicanthic fold of the eyelid, upslanting palpebral fissures (the separation between the upper and lower eyelids), shorter limbs, a single transverse palmar crease (a single instead of a double crease across one or both palms, also called the Simian crease), poor muscle tone, and a larger than normal space between the big and second toes.

Baracat a,b a Department of Gynecology, Federal University of S˜ao Paulo, Escola Paulista de Medicina, Brazil b Department of Gynecology and Obstetrics, University of S˜ao Paulo, Brazil Received 12 November 2006; received in revised form 18 March 2007; accepted 22 April 2007 Abstract Objective: The aim of this study was to evaluate the presence of mutations in the coding region of the QM gene and fragile X in patients with premature ovarian failure and gonadal dysgenesis. Methods: After approval by the local Ethics Committee, blood samples, in EDTA, of 100 normally ovulating women, 23 with premature ovarian failure (POF) and 14 with gonadal dysgenesis 46XX, aged less than 40 years, were screened for mutation in the QM gene coding region. All patients with POF have 46, XX karyotype and serum levels of follicle-stimulating hormone (FSH) over 30 mIU/mL. In addition, all samples from patients with premature ovarian failure underwent analysis for fragile X. Results: The QM gene located at a hotspot region (Xq28) showed five points of mutations in a patient with premature ovarian failure. Four of them were able to change the amino acid sequence of the protein. None of our patients were diagnosed as having pre or mutant X fragile syndrome. Conclusion: Our study suggests that Xq28 (QM gene) may be involved in ovary failure.
