Fingers that are disproportionately narrow (reduced girth) for the hand/foot size or build of the individual.

Arterial inflammation.

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).

Abnormally increased size of the liver.

The presence of chronic diarrhea, which is usually taken to mean diarrhea that has persisted for over 4 weeks.

Neonatal jaundice refers to a yellowing of the skin and other tissues of a newborn infant as a result of increased concentrations of bilirubin in the blood. Neonatal jaundice affects over half of all newborns to some extent in the first week of life. Prolonged neonatal jaundice is said to be present if the jaundice persists for longer than 14 days in term infants and 21 days in preterm infants.

Impaired ability to absorb one or more nutrients from the intestine.

Developmental hypoplasia of the mandible.

A deformity of the chest caused by overgrowth of the ribs and characterized by protrusion of the sternum.

An increased susceptibility to upper respiratory tract infections as manifested by a history of recurrent upper respiratory tract infections (running ears - otitis, sinusitis, pharyngitis, tonsillitis).

An increased susceptibility to lower respiratory tract infections as manifested by a history of recurrent lower respiratory tract infections.

Failure of the immune system to protect the body adequately from infection, due to the absence or insufficiency of some component process or substance.

Systemic inflammatory response to infection.

A chronic skin condition involving the inflammation of the apocrine sweat glands, forming pimple-like bumps known as abscesses.

Infection of the brain parenchyma with herpes simplex virus, resulting in inflammation of the brain parenchyma with neurologic dysfunction.

Infections of the skin that happen multiple times.

An abnormally decreased level of immunoglobulin in blood.

A reduction in the normal proportion of class-switched memory B cells (CD19+/CD27+/IgM+/IgD+) relative to the total number of B cells. Marginal zone B cells undergo limited somatic hypermutation and produce high-affinity IgM and some IgG, whereas class-switched memory B cells synthetize IgG, IgM, and IgA.

The inability to synthesize postvaccination antibodies against a pneumococcus antigen, as measured by antibody titer determination following vaccination.

A decreased concentration of glucose in the blood.

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).

Interalar distance more than 2 SD below the mean for age, or alternatively, an apparently decreased width of the nasal base and alae.

Bizygomatic (upper face) and bigonial (lower face) width are both more than 2 standard deviations below the mean (objective); or, an apparent reduction in the width of the upper and lower face (subjective).

A face with a rounded and slightly elongated outline.

Increased breadth of the nasal bridge (and with it, the nasal root).

Recurrent episodes of ulceration of the oral mucosa, typically presenting as painful, sharply circumscribed fibrin-covered mucosal defects with a hyperemic border.

Distance between the hairline (trichion) and the glabella (the most prominent point on the frontal bone above the root of the nose), in the midline, more than two SD above the mean. Alternatively, an apparently increased distance between the hairline and the glabella.
