HPO HP:0011003 High myopia "A severe form of myopia with greater than -6.00 diopters." [DDD:ncarter] HP:0000545
HPO HP:0001642 Pulmonic stenosis "A narrowing of the right ventricular outflow tract that can occur at the pulmonary valve (valvular stenosis) or just below the pulmonary valve (infundibular stenosis)." [HPO:probinson] Infundibular pulmonic stenosis is mostly caused by overgrowth of the heart muscle wall (hypertrophy of the septoparietal trabeculae). Pulmonic stenosis is often seen as a part of Fallot' s tetralogy, in which case the events leading to the formation of the overriding aorta are also believed to be a cause of the pulmonic stenosis. The pulmonic stenosis is the major cause of the malformations seen in patients with Fallot tetralogy, with the other associated malformations acting as compensatory mechanisms to the pulmonic stenosis. The degree of stenosis varies between individuals with TOF, and is the primary determinant of symptoms and severity. This malformation is infrequently described as sub-pulmonary stenosis or subpulmonary obstruction. HP:0031654
HPO HP:0000939 Osteoporosis "Osteoporosis is a systemic skeletal disease characterized by low bone density and microarchitectural deterioration of bone tissue with a consequent increase in bone fragility. According to the WHO criteria, osteoporosis is defined as a BMD that lies 2.5 standard deviations or more below the average value for young healthy adults (a T-score below -2.5 SD)." [HPO:probinson, PMID:28293453] Osteoporosis is a disease that is characterized by low bone mass, deterioration of bone tissue, and disruption of bone microarchitecture: it can lead to compromised bone strength and an increase in the risk of fractures. HP:0004349
HPO HP:0000974 Hyperextensible skin "A condition in which the skin can be stretched beyond normal, and then returns to its initial position." [HPO:sdoelken] Skin hyperelasticity is to be distinguished from cutis laxa, which refers to extra, redundant skin which tends to hang in folds. HP:0008067
HPO HP:0000175 Cleft palate "Cleft palate is a developmental defect of the palate resulting from a failure of fusion of the palatine processes and manifesting as a separation of the roof of the mouth (soft and hard palate)." [HPO:probinson] Cleft palate is a developmental defect that occurs between the 7th and 12th week of pregnancy. Normally, the palatine processes fuse during this time to form the soft and hard palate. A failure of fusion results in a cleft palate. The clinical spectrum ranges from bifid uvula, to (incomplete or complete) cleft of the soft palate, up to (complete or incomplete) cleft of both the soft and hard palate. HP:0000202, HP:0100737
HPO HP:0001634 Mitral valve prolapse "One or both of the leaflets (cusps) of the mitral valve bulges back into the left atrium upon contraction of the left ventricle." [HPO:probinson] Mitral valve prolapse can be associated with mitral regurgitation. HP:0001633
HPO HP:0001822 Hallux valgus "Lateral deviation of the great toe (i.e., in the direction of the little toe)." [HPO:curators] HP:0010051
HPO HP:0001131 Corneal dystrophy "An abnormality of the cornea that is characterized by opacity of one or parts of the cornea." [HPO:probinson] HP:0000481
HPO HP:0001119 Keratoglobus "Limbus-to-limbus corneal thinning, often greatest in the periphery, with globular protrusion of the cornea." [PMID:19667340] HP:0007700, HP:0100689, HP:0100692
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:0000993 Molluscoid pseudotumors "Bluish-grey, spongy nodules associated with scars over pressure points and easily traumatized areas like the elbows and knees." [HPO:probinson] HP:0011355

The extremities as well as the hands and feet are unusually slim." [DDD:hfirth, HPO:probinson] HP:0000098

HPO HP:0000007 Autosomal recessive inheritance "A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele)." [HPO:probinson] HP:0000005
HPO HP:0000563 Keratoconus "A cone-shaped deformity of the cornea characterized by the presence of corneal distortion secondary to thinning of the apex." [HPO:probinson, PMID:7767020] Keratoconus is an entity characterid by several phenotypic findings such as corneal distortion (secondary to thinning of the apex) and either Fleischer's ring or Vogt's striae. This HPO term intends to denote the finding of corneal distortion and bulge. HP:0100689, HP:0100692

HPO HP:0000572 Visual loss "Loss of visual acuity (implying that vision was better at a certain time point in life). Otherwise the term reduced visual acuity should be used (or a subclass of that)." [HPO:sdoelken] HP:0000505
HPO HP:0001388 Joint laxity "Lack of stability of a joint." [HPO:probinson] Joint laxity may be caused by a number of factors including intraarticular disease and injury or slacking of extraarticular structures such as joint capsules, ligaments, and muscles. HP:0011729
