Total 30 clinical symptoms reported for Linear nevus sebaceus syndrome
| Adenoma sebaceum |
The presence of a sebaceous adenoma with origin in the sebum secreting cells of the skin.
Synonyms:Facial angiofibromas; Sebaceous adenoma |
Very frequent |
| Alopecia |
A noncongenital process of hair loss, which may progress to partial or complete baldness.
Synonyms:Hair loss |
Very frequent |
| Aplasia/Hypoplasia of the cerebellum |
Synonyms:Absent/small cerebellum; Absent/underdeveloped cerebellum; Atrophy/Degeneration affecting the cerebellum; Atrophy/Hypoplasia of the cerebellum; Cerebellar hypoplasia/atrophy |
Very frequent |
| Asymmetric growth |
A growth pattern that displays an abnormal difference between the left and the right side.
Synonyms:Uneven or disproportionate growth of one body part compared to another |
Very frequent |
| Biparietal narrowing |
A narrowing of the biparietal diameter (i.e., of the transverse distance between the protuberances of the two parietal bones of the skull).
|
Very frequent |
| Cavernous hemangioma |
The presence of a cavernous hemangioma. A hemangioma characterized by large endothelial spaces (caverns) is called a cavernous hemangioma.
Synonyms:Cavernous angioma; Cavernous haemangioma; Collection of dilated blood vessels that forms mass |
Very frequent |
| Frontal bossing |
Bilateral bulging of the lateral frontal bone prominences with relative sparing of the midline.
Synonyms:Frontal protruberance; Skull bossing |
Very frequent |
| Genu recurvatum |
An abnormally increased extension of the knee joint, so that the knee can bend backwards.
Synonyms:Back knee; Genu recurvata; Knee hyperextension |
Very frequent |
| Hyperreflexia |
Hyperreflexia is the presence of hyperactive stretch reflexes of the muscles.
Synonyms:Increased deep tendon reflexes; Increased reflexes |
Very frequent |
| Hypotonia |
Hypotonia is an abnormally low muscle tone (the amount of tension or resistance to movement in a muscle). Even when relaxed, muscles have a continuous and passive partial contraction which provides some resistance to passive stretching. Hypotonia thus manifests as diminished resistance to passive stretching. Hypotonia is not the same as muscle weakness, although the two conditions can co-exist.
Synonyms:Low muscle tone; Low or weak muscle tone; Muscle hypotonia; Muscular hypotonia |
Very frequent |
| Intellectual disability |
Subnormal intellectual functioning which originates during the developmental period. Intellectual disability, previously referred to as mental retardation, has been defined as an IQ score below 70.
Synonyms:Intellectual disability; Mental deficiency; Mental retardation; Mental retardation, nonspecific; Mental-retardation; Nonprogressive intellectual disability; Nonprogressive mental retardation |
Very frequent |
| Iris coloboma |
A coloboma of the iris.
Synonyms:Cat eye; Coloboma of iris; Coloboma of the iris; Keyhole iris |
Very frequent |
| Melanocytic nevus |
A oval and round, colored (usually medium-to dark brown, reddish brown, or flesh colored) lesion. Typically, a melanocytic nevus is less than 6 mm in diameter, but may be much smaller or larger.
Synonyms:Beauty mark; Melanocytic naevus; Melanocytic nevi; Nevocellular nevi; Pigmented naevi; Pigmented nevi |
Very frequent |
| Microphthalmia |
A developmental anomaly characterized by abnormal smallness of one or both eyes.
Synonyms:Abnormally small eyeball; Abnormally small globe of eye; Microphthalmos |
Very frequent |
| Prominent occiput |
Increased convexity of the occiput (posterior part of the skull).
Synonyms:Prominent back of the skull; Prominent posterior cranium; Prominent posterior skull; Protruding occiput |
Very frequent |
| Reduced tendon reflexes |
Diminution of tendon reflexes, which is an invariable sign of peripheral nerve disease.
Synonyms:Absent or decreased deep tendon reflexes; Decreased deep tendon reflexes; Decreased tendon reflexes; Decreased to absent deep tendon reflexes; Decreased/absent deep tendon reflexes; Depressed tendon reflexes; Diminished deep tendon reflexes; Diminished or absent deep tendon reflexes; Diminished or absent tendon reflexes; Hypoactive to absent deep tendon reflexes; Impaired tendon reflexes; Reduced/absent deep tendon reflexes; Weak or absent deep tendon reflexes |
Very frequent |
| Seizure |
A seizure is an intermittent abnormality of nervous system physiology characterised by a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain.
Synonyms:Epileptic seizure; Seizures |
Very frequent |
| Telecanthus |
Distance between the inner canthi more than two standard deviations above the mean (objective); or, apparently increased distance between the inner canthi.
Synonyms:Corners of eye widely separated; Dystopia canthorum; Increased distance between medial canthi; Increased intercanthal distance |
Very frequent |
| Ventriculomegaly |
An increase in size of the ventricular system of the brain.
Synonyms:Cerebral ventricular dilatation; Dilated cerebral ventricle; Dilated cerebral ventricles; Dilated ventricles; Enlarged cerebral ventricles; Enlarged ventricles; Enlarged ventricular system; Large cerebral ventricles and cisternae; Ventricular dilatation |
Very frequent |
| Vertebral segmentation defect |
An abnormality related to a defect of vertebral separation during development.
Synonyms:Abnormal spinal segmentation |
