Blepharophimosis plus ovarian failure: a likely candidate for a contiguous gene syndrome.
نویسندگان
چکیده
We describe four females from three families with blepharophimosis, epicanthus inversus, and ptosis who were found to have premature ovarian failure. In two families the inheritance was autosomal dominant and in one it was a new mutation. Two females had, in addition, dysmorphic facial features which have been described in other cases. We suggest that the aetiology of the blepharophimosis ovarian failure syndrome is a contiguous gene syndrome.

We report on ovarian dysfunction in a 3-year-old girl with blepharophimosis, ptosis, and epicanthus inversus syndrome (BPES). A gonadotropin releasing hormone test showed hyperresponses of luteinizing hormone (<0.2-->7.2 mIU/ml) and follicle-stimulating hormone (7.1-->44.8 mIU/ml), and a human menopause gonadotropin test yielded no estradiol response (13-->11 pg/ml). The results suggest that pr...
متن کاملMutations in the coding region of the FOXL2 gene are not a major cause of idiopathic premature ovarian failure.
Premature ovarian failure (POF) is a heterogeneous disorder whose aetiology is still unknown. Recently, the autosomal FOXL2 gene, highly expressed in the adult ovary, has been correlated with the disorder. FOXL2 mutations, causing a truncation of the FOXL2 protein in the forkhead domain or in the poly-Ala tract lead to blepharophimosis-ptosis-epicanthus-inversus syndrome associated with POF (BP...
متن کاملA piggyBac insertion disrupts Foxl2 expression that mimics BPES syndrome in mice.
Blepharophimosis, ptosis, epicanthus inversus syndrome (BPES) is an autosomal dominant genetic disorder characterized by small palpebral fissures and other craniofacial malformations, often with (type I) but could also without (type II) premature ovarian failure. While mutations of the forkhead transcription factor FOXL2 are associated with and likely be responsible for many BPES cases, how FOX...
متن کاملFOXL2 mutations in Chinese patients with blepharophimosis-ptosis-epicanthus inversus syndrome
PURPOSE Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is an autosomal dominant disorder where eyelid malformation associated with (type I) or without (type II) premature ovarian failure (POF). It is ascribed to mutations in the forkhead transcriptional factor2 (FOXL2) gene. The purpose of this study is to identify mutations in FOXL2 of Chinese patients with BPES. METHODS Genomic...
