epicanthal folds

Baker-Gordon Syndrome

Clinical Characteristics
Ocular Features: 

Poor visual acuity described as central in origin with poor eye contact.  Periorbital anomalies of low-set eyebrows and epicanthal folds are common.  The eyes have been described as "almond-shaped".  Strabismus and nystagmus are commonly present.

Systemic Features: 

The facial features ae described as "fine" with a short nose and a thin upper lip.  The forehead is unusually high. 

There is general developmental delay with impaired intellectual development, delayed or absent walking, and behavioral psychiatric manifestations such as stereotypic and unpredictable outbursts.   There are often involuntary and hyperkinetic movements with dystonia, dyskinesia, ataxia and choreoathetosis.  The EEG is often abnormal although seizures have not been reported.

Mental Retardation, AD 31

Clinical Characteristics
Ocular Features: 

A variety of ocular dysmorphisms have been described in this disorder including up-slanting lid fissures, epicanthal folds, hypertelorism, and telecanthus.  Ptosis was described in 1 patient.  Strabismus, nystagmus, and disconjugate gaze have been observed.  Visual acuity has not been reported but "variable visual impairment" has been described.  One patient was considered to have cortical visual impairment.

Systemic Features: 

Neonatal hypotonia and feeding difficulties are among the first signs along with seizure-like activity (50%) including infantile spasms.  EEG anomalies are present in the majority of individuals.  Gastroscopy tubes may be required in a significant minority of patients.  Hypotonic or myopathic facies is common.  Apneic episodes may be seen in the neonatal period and most infants have respiratory difficulties in the first year of life which may improve during this period.  Learning difficulties and features of autism are common.  Some patients are unable to walk while others have an ataxic or broad-based gait.  Speech may be absent or severely limited.  The forehead is prominent while the hard palate is usually highly vaulted.

Brain MRIs may show delayed myelination but such scans have been described as normal in other individuals.  Enlarged ventricles, a thin corpus callosum, and periventricular white matter changes may also be present.   Neuropathologic studies have revealed chronic inflammatory changes around the arterioles of deep while matter.

Hypotonia, Infantile, with Psychomotor Retardation And Characteristic Facies 2

Clinical Characteristics
Ocular Features: 

Anomalies of periocular structures are part of the characteristic facial morphology.  The lid fissures slant downward and epicanthal folds are with ptosis are generally present.  Strabismus and nystagmus are characteristic features.

Systemic Features: 

This is a severe congenital neurodevelopmental disorder with global delay, hypotonia, and characteristic facies.  It is usually present at birth and soon manifest as a profound intellectual delay.  Most patients do not develop speech or independent motor skills.  Feeding difficulties are evident early and often require gastric tube placement for nutrition.  Failure to thrive is common.   Most patients have seizures of a tonic-clonic or atonic type which may be controlled with medication. 

Microcephaly, brachycephaly, plagiocephaly, and brachycephaly have been described.  A high forehead with frontal bossing, facial hypotonia, triangular facies have been described.  The ears are low-set and posteriorly rotated.  The upper lip is often thin and the mouth is commonly open.  The neck appears short, the nose is bulbous while the nasal bridge is prominent and the nares may be anteverted.

Brain imaging is normal in some patients but there is evidence of generalized cerebral atrophy, with a thin corpus callosum and decreased myelination in others.  Variable features such as scoliosis, hip contractures, muscle wasting, and dyskinesias are sometimes seen.

Genetics

This disorder is caused by homozygous or compound heterozygous mutations in the UNC80 gene (2q34).

Carey-Fineman-Ziter Syndrome

Clinical Characteristics
Ocular Features: 

Abnormal eye movements with prominent external ophthalmoplegia are hallmarks of this disease.  An oculomotor nerve palsy with limited abduction and some degree of facial palsy are usually present.  The Moebius sequence is present in many patients.  Epicanthal folds, downslanting lid fissures, and ptosis are frequently seen.

Systemic Features: 

Clinical signs are highly variable.  Unusual facies with features of the Pierre Robin complex are characteristic.  Micrognathia and retrognathia are often present with glossoptosis.  Hypotonia and failure to thrive are commonly seen.  Dysphagia and even absent swallowing likely contribute to this.  Respiratory insufficiency can be present from birth, often with laryngostenosis, and some patients develop pulmonary hypertension and restrictive lung disease as adults.  Progressive scoliosis may contribute to this.  Many patients have club feet with joint contractures.  Skull formation consisting of microcephaly, or macrocephaly, or plagiocephaly is commonly seen.  Cardiac septal defects are common.

Intellectual disability is present in some but not all individuals.  Neuronal heterotopias, enlarged ventricles, reduced white matter, a small brainstem, microcalcifications, and enlarged ventricles have been observed.

PEHO-Like Syndrome

Clinical Characteristics
Ocular Features: 

Poor visual fixation and attention has been noted during the first 6 months of life.  Optic atrophy has been described and epicanthal folds may be present.

Systemic Features: 

General hypotonia with developmental delay and progressive microcephaly are evident in the first 6-12 months of life.  Seizures may be present at birth or within the first month of life.  Edema of the feet, hands, and face are also present at birth.  Cognitive deficits and motor delays are usually evident during infancy.  The central hypotonia may be accompanied by peripheral spasticity.  Kyphoscoliosis often develops.  Other dysmorphic features include micrognathia, narrow forehead, short nose, and open mouth.

Brain imaging reveals coarse pachygyria, polymicrogyria, and dilated ventricles with hypoplastic corpus callosum and pons.  Cerebellar hypoplasia was found in one child. 

Genetics

This presumed autosomal recessive disorder is associated with homozygous mutations in the CCDC88A gene (2p16.1).  Three affected children have been reported in a consanguineous family.

A somewhat similar disorder known as PEHO syndrome (260565) results from homozygous mutations in the ZNHIT3 gene.

Pontocerebellar Hypoplasia 7

Clinical Characteristics
Ocular Features: 

The ocular phenotype has not been fully evaluated.  Optic atrophy, nystagmus, and strabismus have been reported in addition to dysmorphic periocular features such as epicanthal folds, upslanting lid fissures, and a flattened nasal bridge.  Infants frequently do not fix and follow.

Systemic Features: 

Infants may be small at birth and subsequent psychomotor development is delayed.  The ears are large and the palate is highly arched.  Hypotonia is present from birth but spasticity with hyperreflexia may also be seen.  Brain imaging may show a thin corpus callosum as well as olivopontocerebellar hypoplasia.  The ventricles are frequently enlarged.  Patients are frequently irritable with few spontaneous movements.

Genitalia can be ambiguous and are frequently assigned to the female gender because of microphallus, fused scrotum, absent testes, and absence of the uterus.  Many such infants are found to have XY karyotypes.  Infants considered male at birth may subsequently show regression of penile corporeal tissue and may have genitalia that more closely resemble the female gender.  Pelvic imaging and laparoscopy, however, may reveal a uterus, Fallopian tubes and a blind-ending vagina with no gonadal tissue even in individuals with XY karyotypes.

Congenital Heart Defects, Dysmorphic Facies, and Intellectual Developmental Disorder

Clinical Characteristics
Ocular Features: 

The dysmorphic facial features primarily involve the periocular structures.  These include hypertelorism, ptosis, epicanthal folds, strabismus and upslanted palpebral fissures.

Systemic Features: 

Septal defects involving both the atrium and the ventricle are consistently present.  Pulmonary valve abnormalities are present in some patients.

Posteriorly rotated pinnae and a small mouth with a thin upper lip have been observed.  Camptodactyly and clinodactyly are common.  Some patients have mild microcephaly.

Global developmental delay is a consistent feature manifest as delays in walking and speech and eventual intellectual disability.  Feeding difficulties are common.  Hypotonia and hypermobile joints are often noted.  Imaging of the brain may reveal agenesis of the corpus callosum, incomplete formation of the inferior vermis, and leukomalacia of periventricular tissue.

Genetics

Heterozygous mutations have been identified in the CDK13 gene (7p14.1) in seven unrelated individuals.  Heterozygous parents may not have the full phenotype.
