Digits that appear disproportionately short compared to the hand/foot. The word brachydactyly is used here to describe a series distinct patterns of shortened digits (brachydactyly types A-E). This is the sense used here.

The distal and proximal transverse palmar creases are merged into a single transverse palmar crease.

A toe that appears disproportionately short compared to the foot.

Diminished length of one or more metacarpal bones in relation to the others of the same hand or to the contralateral metacarpal.

Clinodactyly refers to a bending or curvature of the fifth finger in the radial direction (i.e., towards the 4th finger).

One or more digit that appears disproportionately short compared to the hand/foot, whereby either the entire digit or a specific phalanx is shortened.

A hole between the two bottom chambers (ventricles) of the heart. The defect is centered around the most superior aspect of the ventricular septum.

A type of cardiomyopathy characterized anatomically by deep trabeculations in the ventricular wall, which define recesses communicating with the main ventricular chamber.

An abnormal restriction of fetal growth with fetal weight below the tenth percentile for gestational age.

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).

Slow or limited growth after birth.

Abnormally increased size of the liver.

Mild intellectual disability is defined as an intelligence quotient (IQ) in the range of 50-69.

A delay in the achievement of motor or mental milestones in the domains of development of a child, including motor skills, speech and language, cognitive skills, and social and emotional skills. This term should only be used to describe children younger than five years of age.

Hypotonia is an abnormally low muscle tone (the amount of tension or resistance to movement in a muscle). Even when relaxed, muscles have a continuous and passive partial contraction which provides some resistance to passive stretching. Hypotonia thus manifests as diminished resistance to passive stretching. Hypotonia is not the same as muscle weakness, although the two conditions can co-exist.

A disorder of bone growth affecting the vertebrae and the ends of the long bones (epiphyses).

Lack of full passive range of motion (restrictions in flexion, extension, or other movements) of the hip joint resulting from structural changes of non-bony tissues, such as muscles, tendons, ligaments, joint capsules and/or skin.

An irregular surface of the vertebral end plates, which are normally relatively smooth.

Generalized muscular hypotonia (abnormally low muscle tone).

Presence of abnormal convexity of the upper and lower end plates of the vertebrae, i.e., an exaggerated bulging out of the upper and lower vertebral end plates.

Head circumference below 2 standard deviations below the mean for age and gender.

An increased susceptibility to pneumonia as manifested by a history of recurrent episodes of pneumonia.

Eczema is a form of dermatitis that is characterized by scaly, pruritic, erythematous lesions located on flexural surfaces.

Increased count of eosinophils in the blood.

Abnormal increased size of the spleen.

Enlargement (swelling) of a lymph node.

Increased susceptibility to otitis media, as manifested by recurrent episodes of otitis media.

The palpebral fissure inclination is more than two standard deviations below the mean.

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

Thinned, deficient, or excessively arched ala nasi.

Anteriorly-facing nostrils viewed with the head in the Frankfurt horizontal and the eyes of the observer level with the eyes of the subject. This gives the appearance of an upturned nose (upturned nasal tip).

Distance between medial and lateral canthi is more than two standard deviations above the mean for age (objective); or, apparently increased length of the palpebral fissures.

Distance between nasal base and midline upper lip vermilion border more than 2 SD above the mean. Alternatively, an apparently increased distance between nasal base and midline upper lip vermilion border.

Height of the vermilion of the upper lip in the midline more than 2 SD below the mean. Alternatively, an apparently reduced height of the vermilion of the upper lip in the frontal view (subjective).

A morphological abnormality of the mouth in which the angle of the mouth is downturned. The oral commissures are positioned inferior to the midline labial fissure.

Eyelashes that draw the attention of the viewer due to increased density and/or length and/or curl without meeting the criteria of trichomegaly.

The birth of a baby of less than 37 weeks of gestational age.

Retinal dystrophy is an abnormality of the retina associated with a hereditary process. Retinal dystrophies are defined by their predominantly monogenic inheritance and they are frequently associated with loss or dysfunction of photoreceptor cells as a primary or secondary event.
