BACKGROUND AND OBJECTIVE Mutations in bone morphogenic protein 15 (BMP15) and growth/differentiation factor 9 (GDF9) lead to altered fertility in animal models. In the human, a heterozygous point mutation of BMP15 has been associated with premature ovarian failure (POF). SUBJECT AND METHODS We have directly sequenced both genes in a cohort of 203 POF(More)
PURPOSE No consensus exists on therapy of elderly cancer patients. Treatments are influenced by unclear standards and are usually less aggressive. This study aims to evaluate determinants and effect of treatment choice on breast cancer prognosis among elderly patients. PATIENTS AND METHODS We reviewed clinical files of 407 breast cancer patients aged >/=(More)
Pachydermoperiostosis, or primary hypertrophic osteoarthropathy (PHO), is an inherited multisystem disorder, whose features closely mimic the reactive osteoarthropathy that commonly accompanies neoplastic and inflammatory pathologies. We previously described deficiency of the prostaglandin-degrading enzyme 15-hydroxyprostaglandin dehydrogenase (HPGD) as a(More)
BACKGROUND The human condition known as Premature Ovarian Failure (POF) is characterized by loss of ovarian function before the age of 40. A majority of POF cases are sporadic, but 10-15% are familial, suggesting a genetic origin of the disease. Although several causal mutations have been identified, the etiology of POF is still unknown for about 90% of the(More)
Preeclampsia is the major pregnancy-induced hypertensive disorder. It modifies the expression profile of placental genes, including several serine protease inhibitors (SERPINs). The objective of this study was to perform a systematic expression analysis of these genes in normal and pathological placentas and to pinpoint epigenetic alterations inside their(More)
In mammals, male fertility is a quantitative feature determined by numerous genes. Until now, several wide chromosomal regions involved in fertility have been defined by genetic mapping approaches; unfortunately, the underlying genes are very difficult to identify. Here, 53 interspecific recombinant congenic mouse strains (IRCSs) bearing 1-2% SEG/Pas (Mus(More)
BACKGROUND FOXL2 encodes a forkhead transcription factor whose mutations are responsible for the blepharophimosis-ptosis-epicanthus inversus syndrome (BPES), involving craniofacial/palpebral abnormalities often associated with premature ovarian failure (POF). RESULTS We describe a FOXL2 variant (p.Gly187Asp) in a case of POF without BPES. The subcellular(More)
Anomalies in gonadal development in a mouse knockout model of Cited2 have been recently described. In Cited2(-/-) female gonads, an ectopic cell migration was observed and the female program of sex determination was transiently delayed. We hypothesize that, in humans, this temporary inhibition of genes should be sufficient to provoke a developmental(More)
Earlier reports demonstrated a key role of Cdkn1b during mouse ovarian development. In this study, the sequencing analysis of the complete coding region of this gene in a panel of premature ovarian failure patients and control subjects reveals a novel mutation potentially related to the phenotype.
