Parkinson disease 25, autosomal recessive early-onset, with impaired intellectual development(PARK25)

MedGen UID:
1845571
Concept ID:
C5882680
Disease or Syndrome
Synonym: PARK25
 
Gene (location): PTPA (9q34.11)
 
Monarch Initiative: MONDO:0957576
OMIM®: 620482

Definition

Parkinson disease-25 (PARK25) is a progressive neurodegenerative disorder characterized by onset of parkinsonism in late childhood/adolescence and developmental delay/impaired intellectual development. Cognitive impairment is mild to moderate and nonprogressive (Fevga et al., 2023). For a general phenotypic description and a discussion of genetic heterogeneity of Parkinson disease, see 168600. [from OMIM]

Clinical features

From HPO
Anxiety
MedGen UID:
1613
Concept ID:
C0003467
Finding
Intense feelings of nervousness, tension, or panic often arise in response to interpersonal stresses. There is worry about the negative effects of past unpleasant experiences and future negative possibilities. Individuals may feel fearful, apprehensive, or threatened by uncertainty, and they may also have fears of falling apart or losing control.
Depression
MedGen UID:
4229
Concept ID:
C0011581
Mental or Behavioral Dysfunction
Frequently experiencing feelings of being down, miserable, and/or hopeless; struggling to recover from these moods; having a pessimistic outlook on the future; feeling a pervasive sense of shame; having a low self-worth; experiencing thoughts of suicide and engaging in suicidal behavior.
Impulse control disorder
MedGen UID:
5769
Concept ID:
C0021122
Mental or Behavioral Dysfunction
Reduced ability to control, or a failure to resist a temptation, urge, or impulse. Examples include disregard for social conventions, general impulsivity, and poor risk assessment.
Restless legs
MedGen UID:
48427
Concept ID:
C0035258
Disease or Syndrome
Restless Leg Syndrome (RLS) is a condition characterized by an uncomfortable and restless sensation in the legs that occurs after going to bed, often leading to insomnia.
Bradykinesia
MedGen UID:
115925
Concept ID:
C0233565
Sign or Symptom
Bradykinesia literally means slow movement, and is used clinically to denote a slowness in the execution of movement (in contrast to hypokinesia, which is used to refer to slowness in the initiation of movement).
Resting tremor
MedGen UID:
66697
Concept ID:
C0234379
Sign or Symptom
A resting tremor occurs when muscles are at rest and becomes less noticeable or disappears when the affected muscles are moved. Resting tremors are often slow and coarse.
Parkinsonism with favorable response to dopaminergic medication
MedGen UID:
375989
Concept ID:
C1846868
Disease or Syndrome
Parkinsonism is a clinical syndrome that is a feature of a number of different diseases, including Parkinson disease itself, other neurodegenerative diseases such as progressive supranuclear palsy, and as a side-effect of some neuroleptic medications. Some but not all individuals with Parkinsonism show responsiveness to dopaminergic medication defined as a substantial reduction of amelioration of the component signs of Parkinsonism (including mainly tremor, bradykinesia, rigidity, and postural instability) upon administration of dopaminergic medication.
Intellectual disability
MedGen UID:
811461
Concept ID:
C3714756
Mental or Behavioral Dysfunction
Intellectual disability, previously referred to as mental retardation, is characterized by subnormal intellectual functioning that occurs during the developmental period. It is defined by an IQ score below 70.
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.
Drooling
MedGen UID:
8484
Concept ID:
C0013132
Finding
Habitual flow of saliva out of the mouth.
