HPO HP:0000946 Hypoplastic ilia "Underdevelopment of the ilium." [HPO:probinson] — HP:0002867
HPO HP:0000947 Dumbbell-shaped long bone "An abnormal appearance of the long bones with resemblance to a dumbbell, a short bar with a weight at each end. That is, the long bone is shortened and displays flaring (widening) of the metaphyses." [HPO:probinson] — HP:0003016
HPO HP:0000951 Abnormality of the skin "An abnormality of the skin." [HPO:probinson] — HP:0001574
HPO HP:0000952 Jaundice "Yellow pigmentation of the skin due to bilirubin, which in turn is the result of increased bilirubin concentration in the bloodstream." [HPO:probinson] — HP:0001005, HP:0001396
HPO HP:0000953 Hyperpigmentation of the skin "A darkening of the skin related to an increase in melanin production and deposition." [HPO:probinson] — HP:0001000
HPO HP:0000954 Single transverse palmar crease "The distal and proximal transverse palmar creases are merged into a single transverse palmar crease." [HPO:probinson, PMID:19125433] The presence of a single palmar crease (instead of the two palmar creases that are typically present). HP:0010490
HPO HP:0000956 Acanthosis nigricans "A dermatosis characterized by thickened, hyperpigmented plaques, typically on the intertriginous surfaces and neck." [DDD:cmoss, PMID:19061584] Acanthosis nigricans is seen in a variety of syndromes including those characterized by insulin resistance or fibroblast growth factor receptor (FGFR) mutations, and may also occur as an adverse effect of several medications that promote hyperinsulinemia. HP:0011368
HPO HP:0000957 Cafe-au-lait spot "Cafe-au-lait spots are hyperpigmented lesions that can vary in color from light brown to dark brown with smooth borders and having a size of 1.5 cm or more in adults and 0.5 cm or more in children." [HPO:probinson] The phrase cafe-au-lait comes from the French word for milk-coffee. A single cafe-au-lait spot can be an isolated finding in otherwise normal individuals. Multiple cafe-au-lait spots often indicate the presence of neurofibromatosis type 1 but may also be seen in other diseases including McCune-Albright syndrome, tuberous sclerosis, and Fanconi anemia. HP:0001034
HPO HP:0000958 Dry skin "Skin characterized by the lack of natural or normal moisture." [HPO:probinson] — HP:0011121

HPO HP:0000961 Cyanosis "Bluish discoloration of the skin and mucosa due to poor circulation or inadequate oxygenation of arterial or capillary blood." [PMID:25658213] — HP:0001005
HPO HP:0000962 Hyperkeratosis "Hyperkeratosis is thickening of the outer layer of the skin, the stratum corneum, which is composed of large, polyhedral, plate-like envelopes filled with keratin which are the dead cells that have migrated up from the stratum granulosum." [HPO:probinson] — HP:0011368
HPO HP:0000963 Thin skin "Reduction in thickness of the skin, generally associated with a loss of suppleness and elasticity of the skin." [HPO:probinson] — HP:0008065
HPO HP:0000964 Eczema "Eczema is a form of dermatitis. The term eczema is broadly applied to a range of persistent skin conditions and can be related to a number of underlying conditions. Manifestations of eczema can include dryness and recurring skin rashes with redness, skin edema, itching and dryness, crusting, flaking, blistering, cracking, oozing, or bleeding." [HPO:probinson] Eczema has several forms including atopic dermatitis, contact dermatitis, dyshidrotic eczema, nummular eczema, seborrheic dermatitis, and stasis dermatitis. HP:0011123
HPO HP:0000965 Cutis marmorata "A reticular discoloration of the skin with cyanotic (reddish-blue appearing) areas surrounding pale central areas due to dilation of capillary blood vessels and stagnation of blood within the vessels. Cutis marmorata generally occurs on the legs, arms and trunk and is often more severe in cold weather." [HPO:sdoelken] — HP:0011276
HPO HP:0000966 Hypohidrosis "Abnormally diminished capacity to sweat." [HPO:probinson] — HP:0007550
HPO HP:0000967 Petechiae "Petechiae are pinpoint-sized reddish/purple spots, resembling a rash, that appear just under the skin or a mucous membrane when capillaries have ruptured and some superficial bleeding into the skin has happened. This term refers to an abnormally increased susceptibility to developing petechiae." [HPO:probinson, PMID:29493956] — HP:0031365
HPO HP:0000968 Ectodermal dysplasia "Ectodermal dysplasia is a group of conditions in which there is abnormal development of the skin, hair, nails, teeth, or sweat glands." [HPO:probinson] This term is kept in the HPO for now as 'ectodermal dysplasia' has been recorded as a phenotypic of other disorders such as DEAFNESS WITH ANHIDROTIC ECTODERMAL DYSPLASIA (MIM125050). Nevertheless it is preferable to use precise descriptions of the phenotypic abnormalities and this term should not be used for new annotations. It will be made obsolete in the future. HP:0011354
HPO HP:0000969 Edema "An abnormal accumulation of fluid beneath the skin, or in one or more cavities of the body." [HPO:probinson] Edema may be related to one or more of the following factors: 1) increased capillary hydrostatic pressure, 2) decreased osmotic pressure of plasma, 3) decreased tissue tension and lymphatic drainage, 4) increased osmotic pressure of tissue fluids, and 5) increased capillary permeability. HP:0011032
HPO HP:0000970 Anhidrosis "Inability to sweat." [HPO:probinson] — HP:0025276
HPO HP:0000971 Abnormal sweat gland morphology "Any structural abnormality of the sweat gland." [HPO:probinson] — HP:0011138
HPO HP:0000972 Palmoplantar hyperkeratosis "Abnormal thickening of the skin localized to the palm of the hand and the sole of the foot." [HPO:probinson] The terms hyperkeratosis and keratoderma have been used interchangeably throughout the literature. HP:0007556, HP:0010765
HPO HP:0000973 Cutis laxa "Wrinkled, redundant, inelastic and sagging skin." [HPO:probinson] — HP:0008067
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:0000975 Hyperhidrosis "Abnormal excessive perspiration (sweating) despite the lack of appropriate stimuli like hot and humid weather." [HPO:probinson] The terms hyperhidrosis and diaphoresis are often used interchangeably to describe excessive perspiration. Diaphoresis can be used to refer to excessive sweating that occurs with certain diseases (secondary hyperhidrosis). Since the HPO does not intend to provide coess for etiologies or diseases, we will use these terms interchangeably to refer to excessive perspiration without an appropriate cause such as hot and humid weather.
