Long eyelashes |
"Mid upper eyelash length >10 mm or increased length of the eyelashes (subjective)." [PMID:19125427, PMID:26288407] |
Measurement should be done on the longest lashes, which are usually at the center of the lid. Normal values are 7.99 - 1.05 mm in boys and 7.76 - 1.03 mm in girls. Note that Eyelash trichomegaly is defined as increase in length (12 mm or more), curling, pigmentation or thickness of eyelashes. |

Failure to thrive |
"Failure to thrive (FTT) refers to a child whose physical growth is substantially below the norm." [HPO:probinson] |
Although there is no clear consensus on the exact definition of FTT, it is usually diagnoses in a child growing below the 3rd percentile or in a child whose decreased growth has cross two major growth percentiles (for example, from above the 75th percentile to below the 25th percentile). |

Decreased response to growth hormone stimulation test |
"Insufficient responses to growth hormone (GH) provocation tests. GH deficiency is defined as a serum peak GH concentration less than 10 ng/mL on provocation with a combination of at least two separate stimulation tests." [HPO:probinson, PMID:25914878] |
GH stimulation tests are performed with various stimuli, such as insulin, L-dopa, arginine, and growth hormone releasing hormone (GHRH). The test using insulin as a stimulus is classically recommended, but this test has potential risks such as hypoglycemia. The effects of growth hormone are mediated almost exclusively by insulin-like growth factor 1(IGF-1), which is produced primarily in the liver. Growth hormone deficiency refers to inadequate levels of GH (and therefore IGF-1), resulting in growth retardation in children and metabolic disturbances in adults. |

Microcephaly |
"Head circumference below 2 standard deviations below the mean for age and gender." [PMID:15806441, PMID:19125436, PMID:25465325, PMID:9683597] |
Head circumference is measured from just above the glabella (the most prominent point on the frontal bone above the root of the nose) to the most posterior prominent point of the occipital bone using a tape measure. Some standard charts are organized by centiles, others by standard deviations. It is important to add an indication of how far below the normal standard the head circumference is if an accurate assessment of this can be made. Microcephaly is an absolute term. The term relative microcephaly can be used when the head size centile is less than the centile for height, for example, head size at the 3rd centile with height at the 75% for age and sex. On prenatal ultrasound, microcephaly is diagnosed if the head circumference or the biparietal diameter is more than three standard deviations below the mean. Microcephaly is divided into primary microcephaly, which is present at birth, and secondary microcephaly, which develops postnatally. The crucial difference between these groupings is that primary microcephaly is usually a static developmental anomaly, whereas secondary microcephaly indicates a progressive neurodegenerative condition |

Stereotypy |
"A stereotypy is a repetitive, simple movement that can be voluntarily suppressed. Stereotypies are typically simple back-and-forth movements such as waving of flapping the hands or arms, and they do not involve complex sequences or movement fragments. Movement is often but not always rhythmic and may involve fingers, wrists, or more proximal portions of the upper extremity. The lower extremity is not typically involved. Stereotypies are more commonly bilateral than unilateral." [HPO:probinson] |
An abnormality of behavior characterized by one or more stereotyped and restricted patterns of behavior such as inflexible adherence to specific, nonfunctional routines or rituals, stereotyped and repetitive motor mannerisms (e.g., hand or finger flapping or twisting, or complex whole-body movements), or persistent preoccupation with parts of objects. The behaviour does not serve an observable goal. In general the movements are not aimed at the environment, but at the person itself. Stereotypical behaviour is seen especially in children with sensory, intellectual and/or cognitive handicaps. |

Hypotonia |
"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." [HPO:probinson, PMID:21418198] |
Hypotonia can be caused by abnormalities of the central nervous system, any element of the motor unit (including the lower motoneuron), or both. Hypotonia is not a specific diagnosis, but can be observed in hundreds of genetic and other diseases. The first distinction to make when assessing a child with hypotonia is whether decreased muscle tone is a result of an abnormality of the central nervous system (CNS), peripheral neuromuscular system, or a combined abnormality involving both. Clinical findings suggestive of an abnormality of the CNS may include hyperreflexia, cognitive developmental delay, and seizures. In contrast, physical findings pointing towards a neuromuscular origin may include weakness, lack of antigravity movements, muscle atrophy, fasciculations, and/or diminished reflexes, most often in the context of normal cognitive function. The HPO term does not distinguish between these etiologies. Additional HPO terms should be used as required to describe associated features. |
