Hereditary Acrokeratotic Poikiloderma (HAP) is a rare genetic skin disorder. “Hereditary” means it’s passed down through families. “Acrokeratotic” refers to thickened skin on the hands and feet. “Poikiloderma” means changes in skin color and texture.
Types:
While various forms can exist depending on specific genetic mutations, they mostly fall under one category: Hereditary Acrokeratotic Poikiloderma of Weary.
Causes (Underlying Genetic Factors):
Technically, the primary cause of HAP is genetic mutations. However, the disorder can manifest differently based on various factors. Here are 20 genes or genetic factors that might influence such conditions:
- DNA replication errors
- UV radiation damage
- Mutated cell-regulating genes
- Faulty DNA repair genes
- Chromosome rearrangements
- Gene deletions
- Telomere shortening
- Epigenetic changes
- Oxidative stress
- Environmental toxins (Keep in mind, these are generic factors linked to genetic disorders; some may not be directly related to HAP.)
Symptoms of HAP:
- Reddish-brown skin patches
- Scaling or thick skin
- Skin atrophy (thin skin)
- Itching
- Freckle-like spots
- Blistering on exposure to sun
- Sparse hair
- Nail abnormalities
- Absent or decreased sweat
- Heat intolerance due to reduced sweating
- Waxy bumps on skin
- Changes in skin pigmentation
- Enlarged blood vessels in skin
- Skin sensitivity to sun
- Dry skin
- Slow-healing sores
- Fragile skin
- Rough patches on palms/soles
- Joint pain
- Fatigue
Diagnostic Tests:
- Skin biopsy
- Genetic testing
- Blood tests
- Dermatoscopy
- Patch testing
- Wood’s lamp examination
- Complete blood count
- Autoantibody testing
- Skin moisture test
- Skin elasticity test
- Direct immunofluorescence
- Electron microscopy
- Ultraviolet (UV) light testing
- Serum protein electrophoresis
- X-rays for bone involvement
- Hair analysis
- Nail analysis
- Allergy tests
- Immunoblotting
- Enzyme-linked immunosorbent assay (ELISA)

In simple terms, Hereditary Acrokeratotic Poikiloderma is a genetic skin disorder. It’s mostly seen as patches of discolored skin that might be thick or thin, with other accompanying symptoms. Diagnosis usually involves skin and genetic tests. There’s no definitive cure, but various treatments and drugs can help manage the symptoms and improve the patient’s quality of life.
