The severity of the ptosis and blepharophimosis require most children to adopt a chin-up backwards head-tilt position and to recruit the frontalis in elevating the lids, leading to raised, arched eyebrows.
Jones and Collin reviewed 37 known cases; of the 6 females of child-bearing age, 1 had primary amenorrhea with raised gonadotropins and low estrogen and progesterone. The clinical diagnosis is confirmed by the identification of a genetic defect in the FOXL2 gene or synddome region.
Standard Therapies Treatment Treatment for BPES needs to address both the eyelid malformation and the premature ovarian insufficienty in type I patients. The third patient, however, had a del 7 q Extraocular manifestations include a broad, flat nasal bridge, arched palate, and cup-shaped ears Allen Familial insertional translocation of a portion of 3q into 11q resulting in duplication and deletion of region 3q People with BPES might be particularly sensitive to bright light, even in winter.
Blepharophimosis, Ptosis, and Epicanthus Inversus syndrome BPES is an ophthalmic disorder characterized by blepharophimosis, ptosis, epicanthus inversus, and telecanthus, that can appear associated with type I or without premature ovarian failure POF; see this term type II.

CC ]. Affected Populations The prevalence of BPES is unknown, but there are no differences in prevalence based on ethnicity, sex, race or age. Despite these common symptoms sufferers may look considerably different from each other.
Early surgery may be necessary for amblyopia. Two of the 3 families had multiple affected members. Retrieved from ” http: Blepharophimosis, ptosis, epicanthus inversus syndrome or BPES is a rare disease characterized by the conditions it is named after: Le blepharophimosis complique familial: About News Events Contact. D ICD – For information about clinical trials conducted in Europe, contact: Type I BPES is characterized by complete penetrance and transmission almost exclusively through males because of impaired female fertility.
The phenotypes of the 2 patients with the chromosome 3 aberrations were similar, but the third had, in addition to features of BPES, genital malformations resembling those of the Smith-Lemli-Opitz syndrome SLO;which maps to 7qqter.
BPES occurs either sporadically de novo or, for the eyelid phenotype, is inherited in an autosomal dominant manner with complete penetrance.
These compensatory mechanisms result in a characteristic facial appearance. However, when ptosis is severe, surgical repair is recommended before age three years. This syndrome is almost always inherited in an autosomal dominant manner. Severe feeding problems and congenital laryngostenosis in a patient with 3q23 deletion. Chromosome studies revealed an interstitial deletion, del 3 qq Blepharophimosis syndrome BPES associated with del 3q Dominant genetic disorders occur when only a single copy of an altered gene is necessary to cause a particular disease.
First described by Komoto inblepharophimosis-ptosis-epicanthus inversus syndrome BPES is a dominantly inherited disorder characterized by four features that are present at birth.
Blepharophimosis sequence and diaphragmatic hernia inveraus with interstitial deletion of chromosome 3 46,XY,del 3 q21q Type II is diagnosed based on the presence of the four major features alone. Sufferers may have a low or flat nasal bridge. Other ophthalmic manifestations that are usually associated with BPES are lacrimal duct anomalies.
It is a genetic disorder affecting most notably the eyelids. Clinical description BPES blephraophimosis congenital and is characterized by a complex bilateral eyelid malformation including blepharophimosis, ptosis, epicanthus inversus and telecanthus. No evidence of genetic heterogeneity was observed.
Other associations include lower lid ectropion, widened nasal bridge or superior orbital rim hypoplasia, or hypertelorism, anteverted ears, and thick highly arched eyebrows. The surgical management is traditionally performed in two stages and involves a medial canthoplasty for correction of the blepharophimosis, epicanthus inversus, and telecanthus at ages epcianthus to five years, followed about a year later by ptosis correction.

Pitfalls in counselling of the blepharophimosis, ptosis, epicanthus inversus syndrome BPES. Complex translocation involving chromosomes Y, 1, and 3 resulting in deletion of segment 3qq ECF1 functioned as an enhancer in reporter gene assays and interacted directly with the Foxl2 promoter in chromosome conformation glepharophimosis assays.
The diagnosis of BPES is based on four clinical findings which are present at the time of birth. Clinical Synopsis Toggle Dropdown.
