HPO HP:0000494 Downslanted palpebral fissures "The palpebral fissure inclination is more than two standard deviations below the mean." [PMID:19125427] HP:0200006
HPO HP:0005280 Depressed nasal bridge "Posterior positioning of the nasal root in relation to the overall facial profile for age." [PMID:19152422] The adjective "depressed" here does not indicate an active process but a status. A depressed nasal bridge can occur irrespective of the width of the nasal bridge, and the width should be assessed independently. In infancy, the nasal bridge is relatively more posterior than in the older person. The term depressed nasal bridge should only be used when the bridge is more posterior than is typical for age and ethnic background. HP:0000422
HPO HP:0011344 Severe global developmental delay "A severe delay in the achievement of motor or mental milestones in the domains of development of a child." [DDD:hvfirth] HP:0001263
HPO HP:0000957 Cafe-au-lait spot "Cafe-au-lait spots are hyperpigmented lesions that can vary in color from light brown to dark brown with smooth borders and having a size of 1.5 cm or more in adults and 0.5 cm or more in children." [HPO:probinson] The phrase cafe-au-lait comes from the French word for milk-coffee. A single cafe-au-lait spot can be an isolated finding in otherwise normal individuals. Multiple cafe-au-lait spots often indicate the presence of neurofibromatosis type 1 but may also be seen in other diseases including McCune-Albright syndrome, tuberous sclerosis, and Fanconi anemia. HP:0001034
HPO HP:0001085 Papilledema "Papilledema refers to edema (swelling) of the optic disc secondary to any factor which increases cerebral spinal fluid pressure." [HPO:probinson] The borders of the optic disc are normally clear and well defined upon fundoscopic examination. Papilledema is optic disc swelling that can lead to the blurring of optic margins and elevation of optic disc. HP:0012795
HPO HP:0000275 Narrow face "Bizygomatic (upper face) and bigonial (lower face) width are both more than 2 standard deviations below the mean (objective); or, an apparent reduction in the width of the upper and lower face (subjective)." [PMID:19125436] Objective measurement of the upper facial width is made with spreading calipers. The tips of the calipers are passed over the zygomatic arches until the maximum width is determined. Objective measurement of the lower faces is made with spreading calipers, with the tips firmly pressed against the inferomedial surface of the angle of the mandible. HP:0000274
HPO HP:0002236 Frontal upsweep of hair "Upward and/or sideward growth of anterior hair." [PMID:19125436] HP:0010721
HPO HP:0000400 Macrotia "Median longitudinal ear length greater than two standard deviations above the mean and median ear width greater than two standard deviations above the mean (objective); or, apparent increase in length and width of the pinna (subjective)." [PMID:19152421] This is acknowledged to be a bundled term but retained here because of its usefulness in practice. Ear length is determined by the maximal distance from the superior aspect to the inferior aspect of the external ear. If only length is increased the term Long ear should be used. HP:0000377
HPO HP:0002808 Kyphosis "Exaggerated anterior convexity of the thoracic vertebral column." [HPO:probinson] HP:0010674
HPO HP:0000276 Long face "Facial height (length) is more than 2 standard deviations above the mean (objective); or, an apparent increase in the height (length) of the face (subjective)." [PMID:19125436] Objective measurement of the face height is made with sliding calipers from the nasion, just above the depth of the nasal root, to the gnathion, the inferior border of the mandible, both in the midline. Note that long face is distinct from narrow face. HP:0100729
HPO HP:0000508 Ptosis "The upper eyelid margin is positioned 3 mm or more lower than usual and covers the superior portion of the iris (objective); or, the upper lid margin obscures at least part of the pupil (subjective)." [PMID:19125427] HP:0012373
HPO HP:0006934 Congenital nystagmus "Nystagmus dating from or present at birth." [HPO:curators] HP:0000639
HPO HP:0004927 Pulmonary artery dilatation "An abnormal widening of the diameter of the pulmonary artery." [HPO:probinson] HP:0030966
HPO HP:0004325 Decreased body weight "Abnormally low body weight." [] HP:0004323
HPO HP:0007018 Attention deficit hyperactivity disorder "Attention deficit hyperactivity disorder (ADHD) manifests at age 2-3 years or by first grade at the latest. The main symptoms are distractibility, impulsivity, hyperactivity, and often trouble organizing tasks and projects, difficulty going to sleep, and social problems from being aggressive, loud, or impatient." [HPO:curators] HP:0000736, HP:0000752
HPO HP:0002650 Scoliosis "The presence of an abnormal lateral curvature of the spine." [HPO:probinson] HP:0010674
HPO HP:0001182 Tapered finger "The gradual reduction in girth of the finger from proximal to distal." [PMID:19125433] HP:0100807
HPO HP:0000276 Long face "Facial height (length) is more than 2 standard deviations above the mean (objective); or, an apparent increase in the height (length) of the face (subjective)." [PMID:19125436] Objective measurement of the face height is made with sliding calipers from the nasion, just above the depth of the nasal root, to the gnathion, the inferior border of the mandible, both in the midline. Note that long face is distinct from narrow face. HP:0100729
HPO HP:0001250 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." [HPO:probinson, PMID:15816939] A type of electrographic seizure has been proposed in neonates which does not have a clinical correlate, it is electrographic only. The term epilepsy is not used to describe recurrent febrile seizures. Epilepsy presumably reflects an abnormally reduced seizure threshold. HP:0012638
HPO HP:0001357 Plagiocephaly "Asymmetric head shape, which is usually a combination of unilateral occipital flattening with ipsilateral frontal prominence, leading to rhomboid cranial shape." [PMID:19125436] Plagiocephaly may affect the posterior skull alone. With plagiocephaly, one can see a combination of unilateral occipital flattening with ipsilateral frontal prominence, leading to rhomboid cranial shape or asymmetry of the posterior skull alone. HP:0002648
HPO HP:0000219 Thin upper lip vermilion "Height of the vermilion of the upper lip in the midline more than 2 SD below the mean. Alternatively, an apparently reduced height of the vermilion of the upper lip in the frontal view (subjective)." [PMID:19125428] Normal values for the height of the vermilion are available [Farkas, 1981], but measurements are not commonly used. Most clinicians determine this feature subjectively or use the Likert scale for Caucasians and African Americans [Astley and Clarren, 2000]. The height of the vermilion of the upper lip varies among ethnic groups, and the vermilion should be compared to a population of same ethnic background. The thinness of the upper lip vermilion is sensitive to facial expression. On profile view, a thin vermilion is less convex than usual. A thin upper lip vermilion may be associated with a smooth philtrum and an absence of the Cupid's bow, but these should be assessed separately. HP:0000233, HP:0011339
HPO HP:0001760 Abnormal foot morphology "An abnormality of the skeleton of foot." [HPO:probinson] A disorder of the foot that can either be congenital or acquired. Such deformities can include hammer toe, club foot deformity, flat feet, pes cavus, congenital vertical talus (rocker bottom foot), and many others. HP:0002814
HPO HP:0000286 Epicanthus "A fold of skin starting above the medial aspect of the upper eyelid and arching downward to cover, pass in front of and lateral to the medial canthus." [HPO:probinson] In extreme cases, the skin fold can start as high as the eyebrow; this is called epicanthus superciliaris. HP:0000492
HPO HP:0001290 Generalized hypotonia "Generalized muscular hypotonia (abnormally low muscle tone)." [HPO:curators] HP:0001252
HPO HP:0003186 Inverted nipples "The presence of nipples that instead of pointing outward are retracted inwards." [HPO:sdoelken] HP:0004404
