Autosomal Dominant Charcot-Marie-Tooth Disease Type 2 due to Kinesin Family Member 5a Mutation

Autosomal dominant CMT2 due to KIF5A mutation is a rare, inherited nerve disorder that mainly damages the axons (the long “wires”) of peripheral nerves. “Autosomal dominant” means a change in a single copy of the KIF5A gene can cause the disease in a family. KIF5A encodes a kinesin motor protein that hauls cargo along microtubules inside nerve cells. When KIF5A is altered, axonal transport breaks down, so long nerves to the feet and hands slowly lose function. People typically develop distal muscle weakness and wasting, foot drop, high arches or hammertoes, impaired balance, and reduced sensation in the feet and hands. Many remain ambulant for life; severity varies—even within the same family. As an axonal CMT (CMT2), nerve conduction speeds are often near-normal or mildly slowed, but the signal amplitudes are reduced because axons are lost. There is no FDA-approved disease-modifying drug for any CMT subtype yet; care focuses on safe, practical ways to maintain function and comfort. Taylor & Francis Online+3NCBI+3PubMed+3

Autosomal dominant Charcot-Marie-Tooth disease type 2 (CMT2) due to KIF5A mutation is a rare, inherited nerve disorder. “Autosomal dominant” means a single changed copy of the gene from either parent can cause the condition. “Type 2” means it mainly affects the axon (the long wire-like part of the nerve), not the myelin insulation. The faulty gene here is KIF5A (kinesin-1 heavy chain), a motor protein that hauls vital cargo along tracks inside nerve cells. When KIF5A is altered, cargo transport becomes slow or blocked, and long peripheral nerves in the feet and hands slowly weaken and lose feeling (a length-dependent axonal neuropathy). Symptoms often begin with foot weakness, ankle sprains, tripping, and numbness, and may slowly move upward over years. Some families show only axonal CMT, while others show a spectrum that can include spasticity (stiffness), or—much less commonly—features that overlap with other disorders linked to KIF5A. PubMed+3rarediseases.info.nih.gov+3NCBI+3

KIF5A sits at the center of a broad phenotype spectrum: certain variants cause axonal CMT2, others cause hereditary spastic paraplegia (SPG10), and still others (especially in the tail domain) are linked to ALS. Which features predominate often depends on where the mutation lies in the protein (motor, stalk, or tail). rarediseases.org+3PMC+3Lippincott Journals+3

Types

Think of “types” here as clinical presentations within KIF5A-related neuropathy. Doctors use these categories to describe what they see, not entirely different diseases:

1. Pure axonal CMT2 phenotype – Slowly progressive weakness and sensory loss in feet and hands; normal or near-normal myelin speeds on nerve tests but low response amplitudes (axon loss). cmtausa.org

2. CMT2 with pyramidal signs (CMT2-HSP overlap) – CMT2 plus mild leg stiffness, brisk reflexes, or spastic gait (partial overlap with hereditary spastic paraplegia/SPG10). PubMed+1

3. CMT2 from KIF5A structural variants (large deletions/duplications) – Same clinical picture as CMT2 but caused by larger DNA changes in KIF5A, not just single-letter variants. PMC

4. Extended KIF5A spectrum (outside classic CMT2) – Tail-domain variants often cause ALS phenotypes; this shows why KIF5A disorders span multiple neurological pictures. (Important for counseling and differential diagnosis—not because individuals with CMT2 necessarily develop ALS.) OUP Academic+1

---

Causes

These “causes” are the underlying mechanisms or triggers that can lead to the CMT2-KIF5A picture. The primary cause is a pathogenic KIF5A variant, but below are the practical sub-causes or pathways that explain why nerves fail in KIF5A-related disease:

1. Pathogenic single-nucleotide variants in KIF5A (motor domain) – Disrupt ATP-driven movement along microtubules, slowing axonal cargo transport. PubMed

2. Pathogenic variants in the KIF5A stalk domain – Alter dimerization/cargo coupling; reported with axonal neuropathy phenotypes. Lippincott Journals

3. Large KIF5A gene deletions – Loss of crucial exons leads to absent or truncated protein and axonal degeneration. PMC

4. Dominant-negative effect – Mutant KIF5A can poison normal protein function within dimers, amplifying transport failure (inferred from kinesin biology). PMC

5. Impaired mitochondrial transport – Mitochondria fail to reach distal axons, starving synapses of energy. (Mechanistic theme across kinesin-related neuropathies.) PMC

6. Defective neurofilament trafficking – Congestion of neurofilaments and axonal structural stress. BioMed Central

7. Axonal energy failure – Long axons are energetically vulnerable; stalled cargo delivery leads to distal axon dying back. NCBI

8. Impaired vesicle and protein delivery to synapses – Shortages of ion channels and synaptic proteins reduce nerve signal reliability. PMC

9. Altered cargo adaptor interactions – Changes in the tail/stalk influence what KIF5A can carry and where it drops cargo. Lippincott Journals

10. Genetic background modifiers – Different family members with the same variant may have milder or more severe neuropathy. PubMed

11. Age-related axonal wear – Long nerves suffer cumulative stress; disease often progresses with age. NCBI

12. Second hits in other neurons/tracts – Some variants also tickle central motor tracts (mild spasticity), broadening the picture. PubMed

13. Microtubule dynamics imbalance – If tracks are unstable, kinesin movement is less effective. (Mechanism inferred from kinesin biology.) PMC

14. Impaired axonal transport in sensory neurons – Explains numbness, reduced vibration sense, and pain. NCBI

15. Length-dependent “dying back” neuropathy – The farthest axon ends (feet) are affected first. NCBI

16. Coexisting musculoskeletal stress – Pes cavus and toe deformities increase strain on weak muscles and nerves. PMC

17. Incorrectly trafficked ion channels – Can reduce nerve conduction reserve and increase fatigue. (General axonal transport principle.) PMC

18. Abnormal neuroinflammatory signaling – Sometimes seen in broader neurodegeneration linked to transport defects; typically modest in CMT2. (Inferred.) PMC

19. Reduced axonal caliber maintenance – Transport deficits impair cytoskeletal renewal, shrinking axons. PMC

20. Lifestyle and neuropathy stressors – Not causative, but diabetes, B12 deficiency, and toxins can worsen an inherited axonal neuropathy—so clinicians screen for and treat them. Medscape

Common symptoms

1. Foot drop and tripping – Weakness of ankle dorsiflexors makes toes catch the ground while walking. NCBI

2. Frequent ankle sprains – Weak peroneal muscles and poor proprioception reduce lateral ankle stability. NCBI

3. High arches (pes cavus) – Muscle imbalance lifts the arch and curls toes over time. PMC

4. Hammertoes/claw toes – Long-standing imbalance in small foot muscles alters toe posture. PMC

5. Calf thinning (atrophy) – Axonal loss leads to visible muscle wasting, especially in the lower legs. NCBI

6. Numbness or tingling in feet – Sensory axons fail to carry normal touch and vibration signals. Cleveland Clinic

7. Loss of vibration sense – A classic sign of large-fiber neuropathy in CMT2. NCBI

8. Reduced/absent ankle reflexes – Damaged axons cannot support normal reflex arcs. nhs.uk

9. Hand weakness (later) – Fine motor tasks like buttoning or writing can become harder as the neuropathy ascends. NCBI

10. Foot fatigue and cramps – Muscles work harder to compensate for weakness and deformity. NCBI

11. Neuropathic pain or burning – Some people experience painful sensory symptoms from axonal damage. Cleveland Clinic

12. Balance problems – Loss of joint-position sense increases unsteadiness, especially in the dark. NCBI

13. Gait changes (steppage gait) – People lift knees higher to avoid dragging toes. NCBI

14. Mild leg stiffness (subset) – A few have brisk reflexes or spasticity due to the KIF5A spectrum touching central motor pathways. PubMed

15. Slow progression over years – Symptoms usually worsen gradually rather than quickly. NCBI

Diagnostic tests

A) Physical examination

1. Gait and foot posture exam – Looks for steppage gait, pes cavus, toe deformities, and ankle instability typical of CMT. PMC

2. Manual muscle testing – Checks strength in ankle dorsiflexion/eversion (often weakest), plantarflexion, intrinsic foot muscles, then hands. NCBI

3. Reflex testing – Ankle reflexes commonly reduced/absent in CMT2; brisk reflexes suggest an overlap with central tract involvement. nhs.uk+1

4. Sensory exam – Tests vibration, pinprick, and proprioception; large-fiber loss fits axonal neuropathy. NCBI

5. Functional assessment – Timed walking, stair tests, and balance tests document disability and monitor change over time. NCBI

B) Manual tests / bedside maneuvers

6. Heel-walk and toe-walk – Screens dorsiflexion and plantarflexion weakness; heel-walk is often impaired early. NCBI

7. Single-leg stance & Romberg – Balance/proprioception checks; sway increases with large-fiber loss. NCBI

8. Foot alignment tests (Coleman block, hindfoot varus assessment) – Clarify fixed vs flexible deformity to guide bracing/orthopedics. PMC

9. Hand dexterity tasks (peg tests, buttoning) – Capture emerging distal hand involvement in later stages. NCBI

C) Laboratory / pathological tests

10. Genetic testing (targeted or panel including KIF5A) – Confirms the diagnosis; testing strategy is guided by family history, exam, and electrodiagnostics. Many centers start with common CMT genes (e.g., PMP22 copy number) and proceed to panels/exome including KIF5A. NCBI+2Louisiana Department of Health+2

11. Copy-number analysis for KIF5A – Detects large deletions/duplications missed by sequencing alone. PMC

12. Metabolic screens (B12, glucose, thyroid, SPEP) – Not to “diagnose” CMT, but to rule out added treatable neuropathy causes that can worsen hereditary neuropathy. Medscape

13. (Rarely) Sural nerve biopsy – Usually unnecessary for CMT2 but may be used when diagnosis is unclear; pathology shows axonal loss without classic demyelination. medlink.com

D) Electrodiagnostic tests

14. Nerve Conduction Studies (NCS) – In CMT2, amplitudes are reduced (axon loss) and velocities are typically >38 m/s (near-normal myelin); contrasts with CMT1 where velocities are <38 m/s. cmtausa.org

15. Electromyography (needle EMG) – Shows chronic denervation/reinnervation in distal muscles; together with NCS, establishes axonal vs demyelinating pattern. AANEM+1

16. Sensory NCS (sural, superficial peroneal) – Often shows low/absent sensory responses in length-dependent axonal neuropathy. Unbound Medicine

17. Motor NCS (peroneal, tibial, median, ulnar) – Helps chart the gradient of axonal loss and asymmetries; useful for follow-up. PubMed

18. Electrodiagnostic differentiation algorithms – Pattern recognition (amplitude vs velocity) helps separate axonal CMT from demyelinating CMT and acquired neuropathies. medlink.com

E) Imaging and supportive tests

19. Foot/ankle X-rays or CT – For fixed deformity planning (e.g., cavovarus), tendon balancing, or osteotomy decisions. PMC

20. Nerve or muscle MRI/ultrasound (selected cases) – Not required for diagnosis but can show atrophy patterns and guide therapy or research assessments. NCBI

Non-pharmacological treatments

These are first-line for daily function and safety in KIF5A-CMT2.

1. Physical therapy (PT) program. A CMT-savvy PT builds a plan to maintain ankle range, strengthen what can strengthen (often proximal and residual distal muscles), and prevent contractures. Regular, moderate exercise helps mobility and reduces falls. cmtausa.org+1

2. Occupational therapy (OT). OT adapts tasks, suggests hand aids (button hooks, built-up pens), and energy-conservation techniques so you can do self-care and work with less fatigue. cmtausa.org

3. Ankle-foot orthoses (AFOs). Properly fitted AFOs reduce tripping from foot drop, improve push-off, and lessen energy cost of walking. Newer carbon-fiber designs are light and springy. cmtausa.org

4. Custom footwear & orthotics. Insoles redistribute pressure under a high-arched foot; wide, stable shoes improve balance; rocker-soles may ease push-off. cmtausa.org

5. Stretching program. Daily calf/Achilles and plantar fascia stretches reduce contractures that worsen cavus and toe clawing. cmtausa.org

6. Strength & balance training. Target proximal hip core and ankle stabilizers; add balance drills and perturbation training to reduce falls. cmtausa.org

7. Aquatic therapy. Buoyancy allows safe endurance and strength work with less joint load and fall risk. Disability Resources

8. Gait aids (trekking poles, cane). Strategic use outdoors or on uneven ground cuts fall risk without over-restricting activity. PMC

9. Hand therapy. Task-specific practice and splints for thumb opposition or wrist stability can extend fine-motor independence. cmtausa.org

10. Pain self-management education. Sleep hygiene, pacing, relaxation/CBT skills help modulate neuropathic pain perception. PMC

11. Skin & foot care routine. Daily checks for blisters/calluses; moisturize dry skin; podiatry for nail care to prevent infections. cmtausa.org

12. Weight management & nutrition basics. Small weight loss can reduce load on unstable ankles and improve endurance. PMC

13. Home safety modifications. Good lighting, grab bars, remove loose rugs, ankle-height hazards—practical fall prevention. PMC

14. Workplace accommodations. Anti-fatigue mats, sit-stand options, reduced lifting, keyboard aids—keeps employment sustainable. cmtausa.org

15. Heat/cold strategies. Some patients prefer warmth for cramps; others use brief topical cooling for burning pain—use cautiously to avoid injury in numb skin. PMC

16. Community exercise. Low-impact cycling, recumbent stepping, and supervised resistance training build capacity safely. PMC

17. Bracing for hands (as needed). Opponens or static resting splints can support weak wrists/thumbs during tasks. cmtausa.org

18. Psychological support. Coping and acceptance therapy can reduce disability from chronic symptoms and enhance adherence. PMC

19. Genetic counseling. Explains inheritance, family testing options, and reproductive choices. NCBI

20. Surgical evaluation (when conservative care fails). Early referral to a foot-and-ankle surgeon experienced in CMT when deformity progresses or bracing no longer works (details below). cmtausa.org

Drug treatments

There are no FDA-approved drugs specifically for CMT (including KIF5A-CMT2) as of October 1, 2025. The medicines below are commonly used to treat neuropathic pain or related symptoms; I cite FDA labels (accessdata.fda.gov) for dosing/safety in their approved indications (e.g., diabetic neuropathy, post-herpetic neuralgia), while clearly noting that use in CMT is off-label. Always individualize with your clinician. Taylor & Francis Online

1. Duloxetine (SNRI). Purpose/mechanism: boosts serotonin–norepinephrine signaling to dampen pain pathways. Dose/time: 30 mg daily for 1 week, then 60 mg daily; no added benefit above 60 mg for pain. Adverse effects: nausea, dry mouth, sleep changes; avoid with MAOIs. Note: FDA-approved for diabetic neuropathic pain and fibromyalgia; off-label for CMT pain. FDA Access Data+1

2. Pregabalin. Purpose/mechanism: binds α2δ subunit of voltage-gated calcium channels to reduce neurotransmitter release. Dose/time: typical 150–300 mg/day in divided doses; adjust for renal function; taper off. Adverse effects: dizziness, somnolence, edema; misuse potential (CV). Off-label for CMT pain; FDA-approved for other neuropathic pains. FDA Access Data

3. Gabapentin. Purpose/mechanism: similar α2δ binding; helps burning/tingling pain. Dose/time: titrate toward 1800–2400 mg/day divided; sedation and dizziness common; taper off. Off-label for CMT pain; label data from postherpetic neuralgia. FDA Access Data+1

4. Capsaicin 8% patch (Qutenza). Purpose/mechanism: high-dose TRPV1 agonist defunctionalizes cutaneous nociceptors, giving months of relief. Use: in-clinic patch application to painful areas (feet); repeat every 3 months as needed. Adverse effects: application-site burning; requires nitrile gloves/ventilation protocols. Approved for PHN and diabetic peripheral neuropathy of the feet; off-label for CMT pain. FDA Access Data+1

5. Lidocaine 5% patch. Purpose/mechanism: local sodium-channel blockade over focal allodynia. Use: apply up to 12 hours/day on painful skin; minimal systemic effects. Approved for PHN; off-label for focal CMT pain. FDA Access Data

6. Tramadol. Purpose: weak μ-opioid agonist/SNRI effects for breakthrough pain when first-line agents fail. Dose/time: immediate-release titration from 25 mg/day; ER forms exist. Risks: dependence, respiratory depression, serotonin syndrome, seizure risk—use sparingly and avoid in high-risk patients. Off-label for CMT pain. FDA Access Data+1

7. Amitriptyline (TCA). Purpose: classic neuropathic pain agent via serotonin/norepinephrine reuptake inhibition plus antihistaminic effects. Dose/time: low dose at night (e.g., 10–25 mg), careful titration; anticholinergic side effects common; ECG caution in elders. Off-label for CMT pain. FDA Access Data

8. Venlafaxine XR (SNRI). Purpose: alternative if duloxetine not tolerated; similar central pain modulation. Dose/time: typically 75–225 mg/day; monitor BP; taper off to avoid withdrawal. Off-label for CMT pain. FDA Access Data

9. Topical agents (lidocaine gel/cream). Purpose: focal pain relief with low systemic exposure; rotate applications and protect numb skin from injury. Label principles mirror 5% patch safety. Off-label for CMT pain. FDA Access Data

10. NSAIDs/acetaminophen. Purpose: helpful for musculoskeletal aches from altered gait or after therapy sessions, not for neuropathic pain itself. Use the lowest effective dose; respect GI/renal risks. (General analgesic labels not shown here as these target nociceptive pain rather than neuropathic.)

11. Baclofen or tizanidine (select cases). Purpose: if spasticity overlaps (rare in pure CMT2 but possible with certain KIF5A variants), low-dose antispasmodics can ease cramps; monitor sedation/weakness. (Use guided by clinician; not CMT-specific.) PubMed

12. Short topical cooling or heat with capsaicin low-dose creams between 0.025–0.1% (OTC) for mild pain. Avoid burns on numb skin. (OTC labeling applies; not disease-specific.) FDA Access Data

If further pharmacologic detail is needed for additional agents (e.g., nortriptyline, duloxetine+pregabalin combinations, or clonazepam for nocturnal cramps), we can add them—but the key point remains: these are symptom-directed and off-label for CMT. There is no approved disease-modifier yet. Taylor & Francis Online

Dietary / molecular supplements

Supplements are not cures. Some have limited or conflicting data from other neuropathies (often diabetic or chemotherapy-induced) rather than CMT. Discuss with your clinician to avoid interactions.

1. Vitamin D (optimize deficiency). Low vitamin D can worsen falls and possibly pain perception. Correct deficiency per standard guidelines; evidence for neuropathic pain benefit is emerging but mixed. PMC+2PMC+2

2. Creatine monohydrate. Can improve strength and fatigue in several neuromuscular disorders; typical loading then 3–5 g/day; monitor GI tolerance. Not disease-modifying for CMT, but may help training response. PMC+1

3. Omega-3 fatty acids. Anti-inflammatory; may support general cardiovascular/nerve health; watch for bleeding risks at high doses.

4. Alpha-lipoic acid (ALA). Recent Cochrane review suggests little or no benefit for neuropathy symptoms at 6 months; if used, do so cautiously and set expectations. cochranelibrary.com+2PMC+2

5. Acetyl-L-carnitine (ALC). Older studies showed possible pain benefit; more recent data in chemotherapy neuropathy warned of potential worsening—so avoid outside trials or specialist advice. PubMed+2PLOS+2

6. Coenzyme Q10. Antioxidant; limited neuropathy data; generally safe but evidence is weak.

7. B-complex (esp. B12 if low). Correct documented deficiency; avoid high-dose B6 which can itself cause neuropathy.

8. Magnesium (for cramps if low). Replace deficiency; high doses may cause diarrhea.

9. Curcumin/turmeric extracts. Anti-inflammatory; limited human neuropathic pain evidence; watch drug interactions.

10. Protein-adequate diet with leucine-rich foods. Supports muscle maintenance when combined with resistance training; not a pill, but a “molecular” nutrition principle.

(Where evidence is cited above, it comes from mixed-population neuropathy trials and systematic reviews, not CMT-specific studies.) PubMed+3cochranelibrary.com+3PMC+3

Immunity-booster / regenerative / stem-cell” drugs

There are no FDA-approved “immunity booster,” regenerative, or stem-cell drugs for CMT2 or KIF5A-related neuropathy. Stem-cell clinics advertising cures for CMT operate outside approved indications and can be risky and expensive. If you see a claim of an approved regenerative drug for CMT, it is incorrect as of October 1, 2025. For research opportunities, discuss clinical trials with your neurologist and consult CMTA/ClinicalTrials.gov listings. Taylor & Francis Online

What is happening in trials? There’s active research across CMT subtypes (e.g., govorestat/AT-007 for CMT-SORD, NMD670 muscle-targeted therapy; orphan designations do not equal approval). These are not KIF5A-specific treatments and remain investigational. cmtausa.org+2NMD Pharma+2

---

Surgeries

1. Tendon transfers (e.g., tibialis posterior transfer). Rebalance muscle forces to lift the foot and reduce clawing; improves function when dorsiflexors/everters are weak but deformity is still flexible. enmc.org

2. Corrective osteotomies. Precisely cut and realign bones (e.g., first metatarsal dorsiflexion osteotomy, calcaneal osteotomy) to flatten a cavus foot and restore plantigrade alignment. PMC

3. Soft-tissue releases. Lengthen tight Achilles/gastrocnemius or plantar fascia to allow a neutral foot position and reduce pressure points. enmc.org

4. Arthrodesis (fusion) in fixed deformity. When joints are rigid and painful, targeted fusions create a stable, plantigrade platform—often after prior soft-tissue/bony balancing. PubMed

5. Peripheral nerve decompression (selected). Carpal/tarsal tunnel release if nerve entrapment adds pain/numbness beyond the baseline neuropathy. (Case selection critical.) In all cases, goals are a plantigrade foot, better shoe wear, fewer falls, and pain reduction; procedures are individualized. PMC+1

---

Preventions

1. Choose stable shoes with good traction; avoid high heels/flip-flops. 2) Inspect feet daily and moisturize; address hot spots early. 3) Keep nails trimmed by a podiatrist if sensation is reduced. 4) Use AFOs or gait aids where recommended. 5) Light your home well; remove trip hazards. 6) Warm-up and stretch before activity. 7) Train balance several times a week. 8) Maintain vitamin D sufficiency and general nutrition. 9) Limit alcohol and keep diabetes risk factors in check. 10) Schedule regular PT/OT refreshers to update braces/exercise plans. cmtausa.org+1

---

When to see a doctor

• Right away for new foot wounds, sudden weakness, frequent falls, severe pain, or medication side effects (confusion, breathing issues, allergic reactions).

• Soon for progressive deformity, AFOs that no longer fit, or worsening numbness/tingling.

• Routine: periodic follow-up with a neuromuscular neurologist, PT/OT, orthotist, podiatrist/foot-ankle surgeon, and genetic counselor to adjust care as needs change. NCBI+1

What to eat & what to avoid

Eat more:

1. Protein at each meal to support training response. 2) Whole grains/legumes for energy. 3) Fruits/vegetables for micronutrients and fiber. 4) Dairy/fortified alternatives for calcium/vitamin D (or supplement if low). 5) Healthy fats (olive oil, nuts, fish).

Limit/avoid:
6) Excess alcohol (neuropathy risk). 7) Very high sugar intake (metabolic health). 8) Smoking (vascular/nerve health). 9) Mega-doses of vitamin B6 (can cause neuropathy). 10) Fad “nerve cure” supplements without evidence. (Nutrition supports function; it does not reverse axonal loss.) PMC

FAQs

1) Is there a cure?
No. As of Oct 1, 2025, no medication reverses KIF5A-CMT2. Research is active; care focuses on maintaining function and safety. Taylor & Francis Online

2) Will I need a wheelchair?
Many people stay ambulant lifelong with AFOs, PT, and, when needed, surgery to maintain a stable, plantigrade foot. PMC

3) What’s the role of surgery?
To correct deformity and restore a plantigrade foot when bracing fails; it’s individualized and often combines tendon transfers with osteotomies, sometimes fusion. enmc.org+1

4) Should I exercise?
Yes—moderate, regular strength and balance work is encouraged; aquatic and cycling options are joint-friendly. Avoid over-fatigue that worsens gait quality. cmtausa.org

5) Are pain medicines lifelong?
Not necessarily. Use the lowest effective dose, reassess regularly, and combine with non-drug strategies (PT, sleep, pacing). All pain drugs listed are off-label for CMT. FDA Access Data+1

6) Can vitamins or supplements cure this?
No. Correct documented deficiencies (e.g., B12, vitamin D). Data for ALA/ALC are mixed or negative; discuss risks/benefits before using. cochranelibrary.com+2PMC+2

7) What about stem-cell therapy?
Not FDA-approved for CMT. Avoid unregulated clinics. Consider vetted clinical trials instead. Taylor & Francis Online

8) Is KIF5A-CMT2 different from CMT1?
Yes. CMT2 is axonal (amplitudes low; velocities near-normal), while CMT1 is demyelinating (markedly slow velocities). NCBI

9) Could I pass this on to my children?
Autosomal dominant inheritance means each child has ~50% chance of inheriting the variant. Genetic counseling helps families plan. NCBI

10) Why do my hands get weak later?
CMT is length-dependent—longest nerves (to feet) fail first; hand symptoms often lag by years. NCBI

11) Are orthoses forever?
AFOs are tools. If surgery corrects alignment, brace needs may decrease, but many still benefit for stability and endurance. cmtausa.org

12) Which doctor should coordinate my care?
A neuromuscular neurologist linked to a CMT Center (when possible), with PT/OT, orthotics, podiatry/orthopedics, and genetics support. PMC

13) Are there promising drugs on the horizon?
Some investigational agents (e.g., govorestat for CMT-SORD; muscle-targeted NMD670) but none yet proven for KIF5A-CMT2. cmtausa.org+1

14) Can depression/anxiety affect symptoms?
Yes—mood and sleep strongly influence pain and activity; treating them improves quality of life and rehab results. PMC

15) What’s the single biggest safety step?
Prevent falls: appropriate AFOs, stable shoes, home hazard fixes, and regular balance work. cmtausa.org
