Dystonia-parkinsonism, Paisán-Ruiz type” refers to an autosomal recessive movement-disorder phenotype caused by biallelic pathogenic variants in the PLA2G6 gene (also known as PARK14). It sits on the spectrum of PLA2G6-associated neurodegeneration (PLAN), alongside infantile neuroaxonal dystrophy and atypical neuroaxonal dystrophy. People usually develop a mix of parkinsonism (slowness/bradykinesia, stiffness/rigidity, sometimes tremor) and dystonia (sustained or twisting muscle contractions), with variable features like early levodopa responsiveness, cognitive changes, cerebellar signs, and—sometimes but not always—iron accumulation in deep brain nuclei on MRI. Crucially, Paisán-Ruiz and colleagues showed PLA2G6 mutations can cause adult-onset levodopa-responsive dystonia-parkinsonism even when brain iron is absent, broadening the phenotype beyond classic NBIA imaging. PubMed+3NCBI+3PMC+3
Dystonia–parkinsonism, Paisán-Ruiz type is a rare, autosomal-recessive movement disorder caused by pathogenic variants in PLA2G6 (a phospholipase A2 gene). It typically starts in childhood to early adulthood and combines two sets of symptoms: (1) parkinsonism (slowness, stiffness, tremor, gait problems) that often responds to levodopa early on, and (2) dystonia (involuntary muscle contractions causing abnormal postures or twisting). Cognition, eye movements, mood/behavior, and pyramidal signs can be involved. Pathology can show Lewy-type and tau accumulation. Importantly, some patients lack classic brain iron changes; that means PLA2G6 should be considered even when MRI doesn’t show iron deposition.

Other names
Doctors and papers may use several interchangeable terms: PLA2G6-related dystonia-parkinsonism, PARK14 dystonia-parkinsonism, PLA2G6-related parkinsonism, adult-onset PLAN (dystonia-parkinsonism subtype), or simply PLAN, DP subtype. All refer to the same gene-defined disorder within the PLAN spectrum. NCBI+1
Types
Within PLAN, clinicians commonly describe four clinical groupings based on age at onset and features: infantile neuroaxonal dystrophy (INAD), atypical neuroaxonal dystrophy (ANAD), adult-onset dystonia-parkinsonism (DP), and autosomal-recessive early-onset parkinsonism (AREP). “Paisán-Ruiz type” usually maps to the DP/AREP end: early-to-adult onset parkinsonism with prominent dystonia, often levodopa responsive, and variable MRI findings (cerebellar atrophy and/or basal ganglia iron may be present or absent). NCBI+2Frontiers+2
Causes
Biallelic PLA2G6 loss-of-function variants. The core cause is inheriting two damaging variants (one from each parent) in PLA2G6, an enzyme (iPLA2β) important for phospholipid remodeling and neuronal membrane homeostasis. NCBI+1
Missense variants that alter catalytic activity. Some missense changes reduce iPLA2β enzymatic function, disturbing membrane repair and signaling in neurons. PMC+1
Frameshift/nonsense variants. Truncating variants can abolish protein production, leading to more severe phenotypes in some families. PMC
Splice-site defects. Abnormal splicing can yield nonfunctional protein or dosage reduction. PMC
Genotype–phenotype effects. Different variants (and their locations) correlate with variable onset and symptoms across PLAN subtypes, including DP. BioMed Central+1
Defective phospholipid remodeling. Impaired repair of membrane phospholipids stresses axons and synapses, promoting neurodegeneration. PMC+1
Mitochondrial dysfunction. Altered lipid metabolism can disturb mitochondrial membranes, energy production, and calcium handling in neurons. PMC
Oxidative stress. Imbalanced lipid turnover increases reactive oxygen species and damages proteins and lipids. PMC
Axonal spheroids. Disrupted axonal transport and membrane turnover create spheroids seen pathologically in PLAN. NCBI
Synaptic dysfunction. Dopaminergic synapses degenerate, driving parkinsonism features.
Dopamine pathway loss. Imaging shows reduced striatal dopaminergic function in PLA2G6-related parkinsonism. BioMed Central
Brain iron dys-homeostasis (variable). Some—but not all—patients show iron accumulation in globus pallidus/substantia nigra, contributing to movement symptoms. ScienceDirect
Cerebellar atrophy (variably present). Purkinje cell and cerebellar involvement can modify gait, balance, and speech. PMC
Genetic background effects. Family-specific or population-specific variants (e.g., reported Iranian founder changes) influence risk and phenotype. BioMed Central
Consanguinity increases biallelic variant risk. Recessive disorders are more frequent in consanguineous pedigrees. BioMed Central
Possible heterozygous modifiers. While disease is recessive, heterozygous variants may modulate risk or features in broader PD cohorts (still under study). Nature
Impaired autophagy/lysosomal pathways. Lipid imbalance secondarily disturbs cellular clearance pathways. ScienceDirect
Neuroinflammation. Lipid peroxidation and cell stress can activate glial responses that worsen neurodegeneration. PMC
Developmental vulnerability of basal ganglia. Nigrostriatal circuits are particularly sensitive to PLA2G6 dysfunction. PMC
Age-related cellular stress. Even in “young” onset, cumulative stress unmasks deficits, shaping when symptoms begin. PMC
Symptoms
Slowness of movement (bradykinesia). Everyday actions—buttoning, writing, walking—become slow and effortful. NCBI+1
Muscle stiffness (rigidity). Arms and legs feel stiff; clinicians feel increased tone when moving the limbs. NCBI
Dystonia. Sustained or twisting postures of the neck, limbs, or face; may worsen with movement or stress. PMC
Tremor (variable). Some have rest tremor like Parkinson’s disease; others do not. Journal of Medical Genetics
Gait difficulty and balance problems. Shuffling, reduced arm swing, and falls can appear early. NCBI
Early levodopa responsiveness. Many improve notably with levodopa, though dyskinesias may occur. PMC+1
Speech changes (dysarthria). Voice may become soft or slurred; words harder to articulate. PMC
Swallowing difficulty (dysphagia). Trouble handling liquids or solids may emerge as disease progresses. PMC
Eye movement problems. Some develop saccadic or pursuit abnormalities, reflecting widespread circuit involvement. PMC
Cognitive changes. Attention, planning, and memory can decline over time in some patients. Frontiers
Psychiatric symptoms. Anxiety, depression, or apathy may occur and deserve treatment. MDPI
Cerebellar signs (variable). In a subset, incoordination or ataxia reflects cerebellar involvement. PMC
Seizures (uncommon but reported). Some adult-onset cases include epilepsy. Tremor and Other Hyperkinetic Movements
Autonomic symptoms. Constipation, urinary urgency, or orthostatic lightheadedness may appear. MDPI
Progression is variable. Course ranges from slowly progressive parkinsonism to broader neurodegeneration across decades. BioMed Central
Diagnostic tests
Physical examination
Full neurological exam. Clinicians assess bradykinesia, rigidity, dystonia patterns, tremor, reflexes, tone, and coordination to recognize a dystonia-parkinsonism syndrome. NCBI
Unified Parkinson’s Disease Rating Scale (UPDRS/MDS-UPDRS). Structured scoring tracks parkinsonian features and treatment response. (Applied in PLA2G6-parkinsonism cohorts.) Journal of Medical Genetics
Dystonia pattern documentation. Distribution (cervical/limb/oromandibular), task-specific triggers, and postural patterns guide diagnosis and therapy. PMC
Cerebellar testing. Finger-nose and heel-knee-shin tests look for ataxia that some PLAN patients show. PMC
Cognitive and psychiatric screening. Brief tools (e.g., MoCA) and targeted questions for mood, anxiety, and apathy help capture non-motor burden. MDPI
Bedside “manual” functional tests
Gait and pull test. Observation of stance, turns, and postural reactions detects instability typical of parkinsonism. NCBI
Handwriting (micrographia) check. Very small, cramped writing supports parkinsonism features. NCBI
Speech and swallowing assessment. Simple bedside tasks (tongue/lip movements, water swallow) screen for dysarthria/dysphagia that need therapy. PMC
Levodopa challenge. Supervised test doses can document responsiveness—a hallmark in many PLA2G6-DP patients. PMC+1
Task-specific dystonia provocation. Writing, playing instruments, or walking can unmask dystonia patterns and guide botulinum toxin targeting. PMC
Laboratory and pathological tests
Molecular genetic testing of PLA2G6. The definitive test is sequencing (and del/dup analysis) to identify biallelic pathogenic variants. Family testing clarifies carrier status. NCBI
Broader movement-disorder gene panels. When the phenotype is unclear, multigene panels that include PLA2G6 can speed diagnosis. NCBI
Rule-out labs for mimics. Copper studies (Wilson disease), thyroid, B12, ceruloplasmin, autoimmune markers, and infection screens help exclude treatable look-alikes. NCBI
Pathology (historical/rarely used). Nerve or brain pathology may show axonal spheroids, but genetics has largely replaced invasive diagnostics. NCBI
Research biomarkers. Work continues on lipid, oxidative-stress, and autophagy markers in PLA2G6 disorders; none yet replace genetic testing. PMC+1
Electrodiagnostic tests
EEG if seizures or episodes of unresponsiveness occur. Some adult PLAN cases report epilepsy; EEG supports evaluation. Tremor and Other Hyperkinetic Movements
EMG for dystonia characterization. Surface EMG can map overactive muscles to guide botulinum toxin injections, though it’s not required for diagnosis. PMC
Imaging tests
Brain MRI. May show cerebellar atrophy, corpus callosum thinning, or iron deposition in basal ganglia—yet some Paisán-Ruiz-type patients have normal iron; MRI supports but does not exclude the diagnosis. PMC+2ScienceDirect+2
Susceptibility-weighted imaging (SWI)/T2.* Sensitive to iron in globus pallidus/substantia nigra and can reveal NBIA-pattern changes when present. ScienceDirect
Dopamine transporter imaging (DaT-SPECT/PET). Studies demonstrate reduced striatal dopaminergic uptake in PLA2G6-related parkinsonism, aligning with clinical bradykinesia and rigidity. BioMed Central
Non-pharmacological treatments (therapies & others)
1) Individualized exercise program (aerobic + resistance).
Purpose: Maintain mobility, strength, and cardiovascular fitness.

Mechanism: External cues bypass impaired basal-ganglia timing by engaging cortical circuits; rhythmic cues can “unlock” gait patterns. Journal of Medical Genetics
3) Balance and postural control therapy.
Purpose: Decrease falls, improve postural reflexes.
Mechanism: Repetitive perturbation and proprioceptive exercises train cerebellar–vestibular compensation when basal-ganglia output is abnormal. Journal of Medical Genetics
4) Stretching and myofascial release for dystonia.
Purpose: Reduce painful spasms and contractures.
Mechanism: Prolonged low-load stretching diminishes spindle hyperexcitability; soft-tissue work reduces trigger-point nociception. Journal of Medical Genetics
5) Constraint and limb-positioning strategies.
Purpose: Limit dystonic overflow into neighboring muscles.
Mechanism: Sensory tricks (“geste antagoniste”), splints, and neutral-wrist/elbow positions temporarily normalize aberrant sensorimotor feedback. Journal of Medical Genetics
6) Occupational therapy (ADL adaptation).
Purpose: Keep independence in dressing, eating, writing, and tech use.
Mechanism: Energy conservation, adaptive utensils, weighted pens, and environmental modifications reduce motor load and tremor amplification. Journal of Medical Genetics
7) Speech-language therapy.
Purpose: Improve hypophonia, dysarthria, and swallowing safety.
Mechanism: High-effort voice training and expiratory muscle strength training enhance breath support; dysphagia protocols reduce aspiration risk. Journal of Medical Genetics
8) Eye-movement/oculomotor rehab where indicated.
Purpose: Ease reading and navigation difficulties.
Mechanism: Saccadic/vergence drills exploit plasticity to compensate for supranuclear oculomotor abnormalities sometimes seen in PLA2G6 disease. PMC

Mechanism: Mechanical stabilization reduces dystonic torque and pain while therapy and botulinum toxin take effect. PMC
16) Heat and hydrotherapy.
Purpose: Relax overactive muscles, improve range of motion.
Mechanism: Warmth lowers alpha-motor neuron firing; buoyancy unloads joints so patients can practice larger, safer movements. Journal of Medical Genetics
17) Mind–body practices (tai chi, yoga, breathing).
Purpose: Improve balance, flexibility, and stress tolerance.
Mechanism: Slow patterned movement and paced breathing modulate autonomic tone and proprioceptive integration. Journal of Medical Genetics
18) Freezing-of-gait strategies (laser lines, metronome).
Purpose: Break “motor blocks.”
Mechanism: External cue entrains step initiation via alternative cortical pathways less reliant on dopaminergic timing. Journal of Medical Genetics
19) Assistive devices (canes, rollators).
Purpose: Safety and endurance.
Mechanism: Enlarged base of support and cueing from wheel rotation can reduce freezing and falls. Journal of Medical Genetics
20) Genetic counseling.
Purpose: Inheritance education and family planning.

Immunity-booster / regenerative / stem-cell” drugs
There are no FDA-approved “stem-cell” or regenerative drugs for PLA2G6 dystonia–parkinsonism. Experimental strategies (e.g., dopaminergic cell grafts, GDNF delivery, gene-directed approaches) are research-only, and dosing should not be attempted outside clinical trials. Discuss trial options at academic centers. For immune health, routine vaccinations, balanced nutrition, sleep, and exercise are safer and evidence-based. Any clinic advertising stem-cell cures for parkinsonism outside trials is not supported by FDA approvals. FDA Access Data+1
