- •Concept ID:
- C0557874
- •
- Finding
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.
Intellectual disability, progressive- MedGen UID:
- 337397
- •Concept ID:
- C1846149
- •

- Finding
Irritability- MedGen UID:
- 397841
- •Concept ID:
- C2700617
- •
- Mental Process
A proneness to anger, i.e., a tendency to become easily bothered or annoyed.
Hyperkinetic movements- MedGen UID:
- 854367
- •Concept ID:

Increased CSF phenylalanine concentration- MedGen UID:
- 1692227
- •Concept ID:
- C5139608
- •
- Finding
Abnormally increased levels of phenylalanine in cerebrospinal fluid.
Hypotonia- MedGen UID:
- 10133
- •Concept ID:
- C0026827
- •
- Finding
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.
Rigidity- MedGen UID:
- 7752
- •Concept ID:
- C0026837
- •
- Sign or Symptom
Continuous involuntary sustained muscle contraction. When an affected muscle is passively stretched, the degree of resistance remains constant regardless of the rate at which the muscle is stretched. This feature helps to distinguish rigidity from muscle spasticity.
Severe muscular hypotonia- MedGen UID:
- 326544
- •Concept ID:
- C1839630
- •
- Finding
A severe degree of muscular hypotonia characterized by markedly reduced muscle tone.
Generalized hypotonia- MedGen UID:
- 346841
- •Concept ID:
- C1858120
- •
- Finding
Generalized muscular hypotonia (abnormally low muscle tone).
Hyperphenylalaninemia- MedGen UID:
- 155558
- •Concept ID:
- C0751435
- •
- Disease or Syndrome
