Kaufman oculocerebrofacial syndrome, also known as blepharophimosis-ptosis-intellectual disability syndrome, is an extremely rare autosomal recessive congenital disorder characterized by severe mental retardation, brachycephaly, upslanting palpebral fissures, eye abnormalities, and highly arched palate.
The fissure may be increased in vertical height in Graves' disease, which is manifested as Dalrymple's sign. It is seen in disorders such as cri-du-chat syndrome. In animal studies using four times the therapeutic concentration of the ophthalmic solution latanoprost, the size of the palpebral fissure can be increased. The condition is reversible.
[2] [3] People with MEDNIK syndrome often have a high forehead, upslanting palpebral fissures, a depressed nasal bridge, low-set ears, growth retardation, and brain atrophy apparent upon imaging. [4] The disorder was discovered by Patrick Cossette and his research team from the Université de Montréal.
Upslanting palpebral fissures; Skeletal indicators Tapering fingers; Hypotonia; Genetics. This condition is caused by mutations in the NR2F1 gene.
Smith-Kingsmore syndrome is a rare genetic disorder that is caused by gain-of-function mutation in a gene MTOR.The facial features of this syndrome are triangular face with a pointed chin, frontal bossing, hypertelorism, eyes with downslanting palpebral fissures, a flat nasal bridge, a long philtrum.
Al-Gazali-Donnai-Mueller syndrome, also known as Hirschsprung's disease, hypoplastic nails, and minor dysmorphic features syndrome [1] is a rare and deadly genetic disorder which is characterized by Hirschsprung's disease, nail and distal limb hypoplasia, flat facies, upslanting palpebral fissures, narrow philtrum, high palate, micrognathia and low-set ears.
The distinct facial feature include upslanting palpebral fissures, a broad nose with rounded tip, long philtrum with a thin upper lip, pointed chin and prominent ears (Vasudevan 2005) Genetics [ edit ]
Dalrymple's sign is a widened palpebral (eyelid) opening, or eyelid spasm, seen in thyrotoxicosis (as seen in Graves' disease, exophthalmic goitre and other hyperthyroid conditions), causing abnormal wideness of the palpebral fissure.
