Alternatively, an apparently increased distance between nasal base and midline upper lip vermilion border.   Synonyms:Elongated philtrum; Increased height of philtrum; Increased length of philtrum; Increased vertical dimension of philtrum; Vertical hyperplasia of philtrum	Very frequent
Micrognathia	Developmental hypoplasia of the mandible.   Synonyms:Decreased size of lower jaw; Decreased size of mandible; Hypoplasia of lower jaw; Hypoplasia of mandible; Hypoplastic mandible; Hypoplastic mandible condyle; Hypotrophic lower jaw; Hypotrophic mandible; Little lower jaw; Little mandible; Lower jaw deficiency; Lower jaw hypoplasia; Lower jaw retrusion; Mandibular deficiency; Mandibular hypoplasia; Mandibular micrognathia; Mandibular retrognathia; Mandibular retrusion; Micrognathia of lower jaw; Micromandible; Robin mandible; Severe hypoplasia of mandible; Small jaw; Small lower jaw; Small mandible; Underdevelopment of lower jaw; Underdevelopment of mandible	Very frequent
Osteolysis	Osteolysis refers to the destruction of bone through bone resorption with removal or loss of calcium.   Synonyms:Breakdown of bone; Increased bone resorption; Osteolytic defects of bones	Very frequent
Osteopenia	Osteopenia is a term to define bone density that is not normal but also not as low as osteoporosis. By definition from the World Health Organization osteopenia is defined by bone densitometry as a T score -1 to -2.5.   Synonyms:Generalized osteopenia	Very frequent
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).	Very frequent
Partial absence of toe	The absence of a phalangeal segment of a toe or hallux.   Synonyms:Hypophalangy of toes; Partial absence of toe	Very frequent
Periodontitis	Inflammation of the periodontium.   Synonyms:Pyorrhea	Very frequent
Short distal phalanx of finger	Short distance from the end of the finger to the most distal interphalangeal crease or the distal interphalangeal joint flexion point. That is, hypoplasia of one or more of the distal phalanx of finger.   Synonyms:Brachytelophalangy; Distal phalangeal hypoplasia; Hypoplasia of the distal phalanges; Hypoplasia of the distal phalanges of the hand; Hypoplasic terminal phalanges; Hypoplastic distal phalanges; Hypoplastic terminal phalanges; Short distal phalanges; Short outermost finger bone; Terminal phalangeal hypoplasia of hand	Very frequent
Short stature	A height below that which is expected according to age and gender norms. Although there is no universally accepted definition of short stature, many refer to 'short stature' as height more than 2 standard deviations below the mean for age and gender (or below the 3rd percentile for age and gender dependent norms).   Synonyms:Decreased body height; Height less than 3rd percentile; Short stature; Small stature; Stature below 3rd percentile	Very frequent
