HPO HP:0010109 Short hallux "Underdevelopment (hypoplasia) of the big toe." [HPO:probinson] HP:0001831, HP:0008362
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:0009778 Short thumb "Hypoplasia (congenital reduction in size) of the thumb." [HPO:probinson] HP:0009381, HP:0009601
HPO HP:0008830 Hypoplastic pubic rami HP:0003173
HPO HP:0000365 Hearing impairment "A decreased magnitude of the sensory perception of sound." [HPO:probinson] Hearing loss can be categorized by which part of the auditory system is damaged, as conductive hearing loss, sensorineural hearing loss, and mixed hearing loss. Another axis of classification uses the degree of hearing impairment. The degree of hearing loss is computed by using a three frequency average taken at 500 Hz, 1,000 Hz and 2,000 Hz. The average of these three frequencies is called the Pure Tone Average (PTA). 0-20 dB is considered normal, 21-40 dB mild loss, 41-60 dB moderate loss, 61-70 dB moderately severe loss,71-90 dB severe loss, and greater than 90 dB profound loss. Note that the word deafness is occasionally used to describe partial hearing loss. The World Health Organization uses the word deafness to refer to complete loss of the ability to hear, and hearing impairment to refer to any degree of reduced hearing. HP:0000364
HPO HP:0000322 Short philtrum "Distance between nasal base and midline upper lip vermilion border more than 2 SD below the mean. Alternatively, an apparently decreased distance between nasal base and midline upper lip vermilion border." [PMID:19152422] HP:0000288
HPO HP:0000520 Proptosis "An eye that is protruding anterior to the plane of the face to a greater extent than is typical." [HPO:sdoelken, PMID:19125427] Some sources define "exophthalmos" as a protrusion of the globe greater than 18 mm and "proptosis" as a protusion equal to or less than 18 mm. Others define "exophthalmos" as protusion secondary to endocrine dysfunction and "proptosis" as any non-endocrine-mediated protusion (Source: Wikipedia). This finding should be distinguished frm underdevelopment of the supraorbital ridge or maxilla/zygoma. In proptosis, the globe is anteriorly protuberant to the overall plane of the face. HP:0100886
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:0001274 Agenesis of corpus callosum "Absence of the corpus callosum as a result of the failure of the corpus callosum to develop, which can be the result of a failure in any one of the multiple steps of callosal development including cellular proliferation and migration, axonal growth or glial patterning at the midline." [HPO:curators] HP:0007370
HPO HP:0001631 Atrial septal defect "Atrial septal defect (ASD) is a congenital abnormality of the interatrial septum that enables blood flow between the left and right atria via the interatrial septum." [DDD:dbrown, HPO:probinson] HP:0005120, HP:0011994
