HPO HP:0001385 Hip dysplasia "The presence of developmental dysplasia of the hip." [HPO:probinson] HP:0003272
HPO HP:0001105 Retinal atrophy "Well-demarcated area(s) of partial or complete depigmentation in the fundus, reflecting atrophy of the retinal pigment epithelium with associated retinal photoreceptor loss." [ORCID:0000-0003-0986-4123] HP:0000546
HPO HP:0010863 Receptive language delay "A delay in the acquisition of the ability to understand the speech of others." [HPO:probinson] HP:0000750
HPO HP:0001761 Pes cavus "The presence of an unusually high plantar arch. Also called high instep, pes cavus refers to a distinctly hollow form of the sole of the foot when it is bearing weight." [HPO:probinson, PMID:19125433] HP:0001760
HPO HP:0000431 Wide nasal bridge "Increased breadth of the nasal bridge (and with it, the nasal root)." [HPO:probinson, PMID:19152422] Care should be taken to distinguish between increased width of bone and Fullness of paranasal tissue. A wide nasal bridge should be distinguished from Telecanthus and Hypertelorism. A wide nasal bridge can be either prominent or depressed, which should be coded separately. HP:0000422
HPO HP:0002616 Aortic root aneurysm "An abnormal localized widening (dilatation) of the aortic root." [] HP:0012727
HPO HP:0004482 Relative macrocephaly "A relatively mild degree of macrocephaly in which the head circumference is not above two standard deviations from the mean, but appears dysproportionately large when other factors such as body stature are taken into account." [HPO:curators] HP:0000256
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:0000160 Narrow mouth "Distance between the commissures of the mouth more than 2 SD below the mean. Alternatively, an apparently decreased width of the oral aperture (subjective)." [PMID:19125428] The width of the mouth varies with facial movement and must be assessed when the subject has a relaxed (neutral) face. This term replaces microstomia, small oral aperture, and small mouth because the reduced opening of the mouth is secondary to reduced width. HP:0011337
HPO HP:0010055 Broad hallux "Visible increase in width of the hallux without an increase in the dorso-ventral dimension." [PMID:19125433] Note that girth may be increased in a broad hallux, but this must be distinguished from Macrodactyly because there the length is also increased. This assessment may be difficult when the hallux is short. HP:0001837, HP:0001844
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:0002194 Delayed gross motor development "A type of motor delay characterized by a delay in acquiring the ability to control the large muscles of the body for walking, running, sitting, and crawling." [HPO:probinson] HP:0001270
HPO HP:0000729 Autistic behavior "Persistent deficits in social interaction and communication and interaction as well as a markedly restricted repertoire of activity and interest as well as repetitive patterns of behavior." [HPO:probinson, PMID:28879490] This term can be used to refer to autism spectrum disorder as a phenotypic feature that can be a component of a disease. Autism spectrum disorder range from a severe form, called autistic disorder, to a milder form, Asperger syndrome. HP:0000708
HPO HP:0000218 High palate "Height of the palate more than 2 SD above the mean (objective) or palatal height at the level of the first permanent molar more than twice the height of the teeth (subjective)." [PMID:19125428] The measuring device for this assessment is described in (Hall JG, Froster-Iskenius UG, Allanson JE, Gripp K, Slavotinek A. 2006. Handbook of Normal Physical Measurements. 2nd edition. Oxford Medical, publishers). A high palate is often associated with a narrow palate. However, a narrow palate can easily give a false appearance of a high palate. Height and width of the palate should be assessed and coded separately. We do not recommend the subjective determination because this term can be overused and\napplied inaccurately. HP:0000174
HPO HP:0000405 Conductive hearing impairment "An abnormality of vibrational conductance of sound to the inner ear leading to impairment of sensory perception of sound." [HPO:probinson] A conductive hearing impariment with greater than 90 dB loss. HP:0000365, HP:0011452
HPO HP:0011968 Feeding difficulties "Impaired ability to eat related to problems gathering food and getting ready to suck, chew, or swallow it." [ISCA:eriggs] HP:0011458
HPO HP:0000233 Thin vermilion border "Height of the vermilion of the medial part of the lip more than 2 SD below the mean, or apparently reduced height of the vermilion of the lip in the frontal view. The vermilion is the red part of the lips (and confusingly, the vermilion itself is also often referred to as being equivalent the lips)." [HPO:probinson, PMID:19125428] The vermilion is the red part of the lips, and the vermilion border is the rim of paler skin that demarcates the vermilion from the rest of the skin of the face. HP:0000159
HPO HP:0001611 Nasal speech "A type of speech characterized by the presence of an abnormally increased nasal airflow during speech." [HPO:sdoelken] May be associated with incomplete or weak closure of the velum. Examination is by nasal endoscopy. HP:0001608
HPO HP:0025269 Panic attack "A sudden episode of intense fear in a situation in which there is no danger or apparent cause." [PMID:28613692] The panic attack is accompanied by symptoms such as palpitations, sweating and chills or hot flushes. There may be a sensation of dyspnea (being out of breath), chest pain, or abdominal distress. Some individuals with panic attacks may experience depersonalization, a fear of going crazy, or a fear of dying. HP:0033052, HP:0100852
HPO HP:0001519 Disproportionate tall stature "A tall and slim body build with increased arm span to height ratio (>1.05) and a reduced upper-to-lower segment ratio (<0.85), i.e., unusually long arms and legs. The extremities as well as the hands and feet are unusually slim." [DDD:hfirth, HPO:probinson] HP:0000098
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:0000343 Long philtrum "Distance between nasal base and midline upper lip vermilion border more than 2 SD above the mean. Alternatively, an apparently increased distance between nasal base and midline upper lip vermilion border." [PMID:19152422] HP:0000288
HPO HP:0001382 Joint hypermobility "The ability of a joint to move beyond its normal range of motion." [HPO:probinson] HP:0011729
HPO HP:0000581 Blepharophimosis "A fixed reduction in the vertical distance between the upper and lower eyelids with short palpebral fissures." [PMID:19125427] When the palpebral fissures are severely shortened, they cannot be widely separated, actively or passively. Blepharophimosis is an acknowledged bundled term (short vertical and horizontal distance). When palpebral fissures are severely shortened, they cannot be widely separated, actively or passively. Ptosis is the term to be used when the reduction in eyelid opening is not fixed but can be increased actively or passively. Blepharophimosis is often associated with Epicanthus inversus. HP:0200007
HPO HP:0011098 Speech apraxia "A type of apraxia that is characterized by difficulty or inability to execute speech movements because of problems with coordination and motor problems, leading to incorrect articulation. An increase of errors with increasing word and phrase length may occur." [HPO:probinson] Speech apraxia may co-occur with oral apraxia and limb apraxia. HP:0002186
