Summaries for Kaufman Oculocerebrofacial Syndrome

Genetics Home Reference : 25 Kaufman oculocerebrofacial syndrome is a disorder characterized by eye problems (oculo-), intellectual disability (-cerebro-), and a distinctive pattern of facial features (-facial). Most individuals with Kaufman oculocerebrofacial syndrome have an unusually small head size (microcephaly), and some have structural abnormalities of the brain. Affected individuals have weak muscle tone (hypotonia), and are delayed in developing motor skills such as walking. Intellectual disability is severe or profound. Most affected individuals never acquire the ability to speak. Eye abnormalities and their effect on vision vary among people with Kaufman oculocerebrofacial syndrome. Some people with this disorder have abnormally small or poorly developed eyes (microphthalmia); microcornea, in which the clear front covering of the eye (cornea) is small and abnormally curved; missing pieces of tissue in structures that form the eye (coloboma); or underdevelopment of the nerves that carry signals between the eyes and the brain (optic nerve hypoplasia). Eyes that do not look in the same direction (strabismus), nearsightedness (myopia) or farsightedness (hyperopia), or an inward turning of the lower eyelid (entropion) can also occur. Individuals with Kaufman oculocerebrofacial syndrome typically have a characteristic pattern of facial features. These include highly arched eyebrows, an increased distance between the inner corners of the eyes (telecanthus), a narrowing of the eye opening (blepharophimosis), skin folds covering the inner corner of the eyes (epicanthal folds), droopy eyelids (ptosis), and outside corners of the eyes that point upward (upslanting palpebral fissures). Ear abnormalities include low-set ears with small lobes and growths of skin (skin tags) in front of the ear (preauricular tags). The nose has a narrow bridge, a wide base, and nostrils that open to the front rather than downward (anteverted nares). Affected individuals may also have flat cheeks; a space between the nose and upper lip (philtrum) that is unusually long and smooth; a narrow mouth; and an unusually small jaw (micrognathia). Other signs and symptoms that can occur in people with this disorder include short stature; hearing loss; and abnormalities of the heart, respiratory tract, gastrointestinal tract, kidneys, genitals, or skeleton. Affected individuals can live into adulthood; however, their average life expectancy is unknown because of the small number of people who have been diagnosed with this disorder.

MalaCards based summary : Kaufman Oculocerebrofacial Syndrome, also known as blepharophimosis-ptosis-intellectual disability syndrome, is related to platelet groups--ko system and disseminated intravascular coagulation. An important gene associated with Kaufman Oculocerebrofacial Syndrome is UBE3B (Ubiquitin Protein Ligase E3B). Affiliated tissues include eye, skin and brain, and related phenotypes are intellectual disability and global developmental delay

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 2707DefinitionOculocerebrofacial syndrome, Kaufman type is characterized by psychomotor retardation, microcephaly, upslanting palpebral fissures, eye abnormalities (microcornea, strabismus, myopia, optic atrophy), high-arched palate, preauricular skin tags and micrognathia with respiratory distress. It has been described in about 10 cases. Other anomalies can be present: long thin hands and feet, ambiguous genitalia, hypertelorism, etc. An autosomal recessive mode of inheritance seems most likely.Visit the Orphanet disease page for more resources.

UniProtKB/Swiss-Prot : 74 Kaufman oculocerebrofacial syndrome: A syndrome characterized by blepharophimosis, ptosis, mild upslanting of the palpebral fissures, epicanthus, ectodermal anomalies, developmental delay, and severe intellectual disability with absent speech. Proportionate growth retardation with a small head circumference/microcephaly, congenital malformations, muscular hypotonia, anomalies on brain imaging with hypoplasia of the corpus callosum, and low cholesterol levels are variably present.
