HPO HP:0011302 Long palm "For children from birth to 16 years of age the length of the palm is more than the 97th centile; or, the length of the palm appears relatively long compared to the finger length or the limb length." [PMID:19125433] HP:0100871
HPO HP:0000486 Strabismus "A misalignment of the eyes so that the visual axes deviate from bifoveal fixation. The classification of strabismus may be based on a number of features including the relative position of the eyes, whether the deviation is latent or manifest, intermittent or constant, concomitant or otherwise and according to the age of onset and the relevance of any associated refractive error." [HPO:probinson, PMID:26319345, UManchester:psergouniotis] HP:0000549
HPO HP:0000347 Micrognathia "Developmental hypoplasia of the mandible." [HPO:probinson] Mandibular hypoplasia, also known as micrognathia, is a term that describes an abnormally small lower jaw. HP:0009118
HPO HP:0000670 Carious teeth "Caries is a multifactorial bacterial infection affecting the structure of the tooth. This term has been used to describe the presence of more than expected dental caries." [HPO:probinson] It should be noted that it is not always possible to rule out environmental influences and that reports of association between hereditary diseases and susceptibility to dental caries should be regarded with caution. HP:0011061
HPO HP:0001270 Motor delay "A type of Developmental delay characterized by a delay in acquiring motor skills." [HPO:probinson] HP:0012758
HPO HP:0000506 Telecanthus "Distance between the inner canthi more than two standard deviations above the mean (objective); or, apparently increased distance between the inner canthi." [HPO:probinson] Dystopia canthorum (also called telecanthus) describes a subtle but unusual facial feature in which the inner corners of the eyes (canthi) are spaced farther apart than normal, yet the eyes (pupils) themselves are not necessarily widely spaced. HP:0000492
HPO HP:0001840 Metatarsus adductus "The metatarsals are deviated medially (tibially), that is, the bones in the front half of the foot bend or turn in toward the body." [HPO:probinson, PMID:19125433] Metatarsus varus (adductus) is one of the most common foot deformities, that is defined as a transverse plane deformity in Lisfranc's (tarsometatarsal) joints in which the metatarsals are deviated medially. The relationship between talus and calcaneus is normal. On inspection the toes angle abruptly towards the midline, creating a C-shaped lateral foot border with a prominent styloid process of the 5th metatarsal. The result is that the forefoot is twisted inwards relative to the heel, so that the sole faces the midline. HP:0001832
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:0000319 Smooth philtrum "Flat skin surface, with no ridge formation in the central region of the upper lip between the nasal base and upper vermilion border." [PMID:19152422] There is a spectrum of this finding from total absence of the philtral ridges to a some prominence of the ridges. The central groove varies from absent to shallow. Normal values for the frequency of smooth philtrum are available. Grading of the smoothness of the philtrum, used in the assessment of Fetal Alcohol Syndrome, has been developed. This finding is greatly influenced by the facial expression, and care should be taken to evaluate the philtrum when the face is in a neutral position. A smooth philtrum can be associated with a Long philtrum. However, the two findings should be coded separately. HP:0000288
HPO HP:0000639 Nystagmus "Rhythmic, involuntary oscillations of one or both eyes related to abnormality in fixation, conjugate gaze, or vestibular mechanisms." [HPO:curators] HP:0012547
HPO HP:0000482 Microcornea "A congenital abnormality of the cornea in which the cornea and the anterior segment of the eye are smaller than normal. The horizontal diameter of the cornea does not reach 10 mm even in adulthood." [HPO:probinson] Note that the cornea's diameter is normally about 9.5-10.0 mm at birth and reaches 10.0-12-5 mm in adulthood. HP:0001120
HPO HP:0000316 Hypertelorism "Interpupillary distance more than 2 SD above the mean (alternatively, the appearance of an increased interpupillary distance or widely spaced eyes)." [PMID:19125427] HP:0100886
HPO HP:0008070 Sparse hair "Reduced density of hairs." [HPO:probinson, PMID:14676077] This term applies if the number of hair shafts per unit area is reduced. The term fine hair is used to describe hair with a reduced diameter. HP:0011362
HPO HP:0000377 Abnormality of the pinna "An abnormality of the pinna, which is also referred to as the auricle or external ear." [HPO:probinson] The term 'dysplastic' is no longer accepted as a descriptor for an ear with unusual morphology. Each specific anatomical component of the ear should be described when the ear is thought to be abnormal in appearance. HP:0000356
HPO HP:0000483 Astigmatism "A type of astigmatism associated with abnormal curvatures on the anterior and/or posterior surface of the cornea." [DDD:ncarter, HPO:probinson, ORCID:0000-0003-0986-4123] The irregular curvature associated with astigmatism means that the optical system is not symmetric about the optical axis. Most commonly the cornea is affected such that the refractive power in one meridian is less than that of the perpendicular axis. Astigmatism of significant degree causes blurry vision. HP:0000539, HP:0100691
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:0000384 Preauricular skin tag "A rudimentary tag of skin often containing ear tissue including a core of cartilage and located just anterior to the auricle (outer part of the ear)." [HPO:probinson] HP:0000383, HP:0010609
HPO HP:0001680 Coarctation of aorta "Coarctation of the aorta is a narrowing or constriction of a segment of the aorta." [HPO:probinson, PMID:23909637] Coarctation refers to a narrowing of the lumen of a vessel producing an obstruction to flow. Coarctation can occur in any region of the aorta. Coarctation of the aorta is often a discrete obstruction commonly located in the descending thoracic aorta. More specifically, it is usually located in the juxtaductal position immediately distal to the left-subclavian artery in a left-sided arch. The hallmark clinical finding in coarctation of the aorta is hypertension proximal to the lesion, with diminished blood pressure distal to the obstruction. Consequently, clinical diagnosis can be made by the presence of diminished lower extremity pulses, differences in timing between upper extremity central pulses (often brachial) and lower extremity central pulses (often femoral), or the presence of a supine arm-leg blood pressure gradient. HP:0001679
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:0010864 Intellectual disability, severe "Severe mental retardation is defined as an intelligence quotient (IQ) in the range of 20-34." [HPO:probinson] Persons with severe mental retardation can be taught basic life skills and simple tasks with supervision. HP:0001249
HPO HP:0001290 Generalized hypotonia "Generalized muscular hypotonia (abnormally low muscle tone)." [HPO:curators] HP:0001252
HPO HP:0003196 Short nose "Distance from nasion to subnasale more than two standard deviations below the mean, or alternatively, an apparently decreased length from the nasal root to the nasal tip." [HPO:probinson, PMID:19152422] Note: a small nose has both decreased height and a decreased width. These should be coded separately. HP:0005105
HPO HP:0006511 Laryngeal stridor "An abnormal high-pitched noisy sound, occurring during inhalation or exhalation caused by the incomplete obstruction in the throat." [HPO:probinson] The laryngeal stridor sound is usually heard during inspiratory phase, also called inspiratory stridor, and may accompanied by inspiratory difficulty in breathing. It may be due to abnormal flaccidity of the epiglottis or arytenoids. HP:0025424
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:0000545 Myopia "An abnormality of refraction characterized by the ability to see objects nearby clearly, while objects in the distance appear blurry." [HPO:probinson] HP:0000539
