Absence of fingerprints–congenital milia syndrome is a very rare genetic skin condition. Babies are born with no fingerprints on their fingers, palms, toes, or soles. Soon after birth, they also get tiny white cysts on the face called milia, and sometimes small blisters on the hands and feet. Many children and adults also sweat less on the palms and soles (hypohidrosis). The skin can be unusually thin or thick in places. Most people are otherwise healthy and live a normal life. But not having fingerprints can make identity checks harder, and reduced sweating can raise the risk of heat stress in hot weather. This condition is usually lifelong. Orpha.net+2National Organization for Rare Disorders+2
Absence of fingerprints-congenital milia syndrome is an extremely rare, inherited skin condition. Babies are born without fingerprints (no dermatoglyphs) and often develop tiny white facial bumps (milia) and blisters on the hands and feet in early life. Sweating on the palms/soles may be reduced (hypohidrosis), so people can overheat. Life expectancy is normal; most problems are practical (e.g., fingerprint-based ID systems) and comfort-related (friction, heat). The condition is usually autosomal dominant (it can pass from one affected parent). Names you may see include Basan syndrome, Baird syndrome, absence of dermatoglyphics with congenital milia, adermatoglyphia with neonatal acral bullae. Orpha.net+2MedlinePlus+2
The condition is linked to changes in a gene called SMARCAD1 (a chromatin-remodeling gene). A skin-specific isoform of SMARCAD1 is important for forming normal epidermal ridges (fingerprints). When this isoform is disrupted, the ridges do not form, and the skin barrier can blister more easily in newborns; milia may appear on the face. PMC+2PMC+2
Scientists group this disorder with a family of conditions called adermatoglyphia syndromes (conditions with absent fingerprint ridges). In this specific syndrome, the key duo is no fingerprints plus congenital facial milia (the tiny white bumps). It is most often inherited in an autosomal dominant way, which means one affected parent can pass it on to a child. Very few families in the world are known, so it is extremely rare. Wikipedia+1
Other names
Doctors and databases use several names for the same condition. All point to the same clinical picture.
Basan syndrome.
Absence of fingerprints–congenital milia syndrome (formal name).
Absence of dermatoglyphics with congenital milia (dermatoglyphics = fingerprint ridges).
Adermatoglyphia with congenital facial milia and acral blisters.
“Absence of fingerprints–congenital milia” in Orphanet/Monarch/NORD entries. Orpha.net+2monarchinitiative.org+2
Some people have isolated adermatoglyphia, which means they have no fingerprints but no milia and no newborn blisters. That isolated form is often called the “immigration delay disease” and is linked to changes in a gene called SMARCAD1. The Basan form adds congenital facial milia and newborn blisters on hands and feet. Two other related disorders, Naegeli–Franceschetti–Jadassohn syndrome (NFJS) and Dermatopathia pigmentosa reticularis (DPR), also lack fingerprints but have net-like skin darkening, nail and hair changes, and dental issues; those are caused by KRT14 gene mutations. PMC+2PMC+2
Types
You may hear doctors talk about “types” based on the pattern of features and the gene involved:
Basan syndrome (this condition). No fingerprints, facial milia, newborn blisters on hands/feet, less sweating on palms/soles. Usually autosomal dominant. NCBI
Isolated adermatoglyphia. Only the fingerprints are missing; usually fewer sweat gland openings on palms/soles; typically due to SMARCAD1 (skin-specific isoform) variants. PMC
NFJS (Naegeli–Franceschetti–Jadassohn syndrome). No fingerprints plus net-like pigmentation, nail/hair/teeth changes; due to KRT14 variants. Frontiers
DPR (Dermatopathia pigmentosa reticularis). Similar to NFJS with reticulate pigmentation, nail and hair changes, sometimes adermatoglyphia; also KRT14. PMC
These “types” help with genetic counseling and testing, but the day-to-day care for Basan syndrome is mainly skin care and heat safety.
Causes
“Cause” here means the underlying changes that lead to the signs you see. This condition is genetic and usually due to a pathogenic change in the SMARCAD1 gene that is active in skin. Below are 20 contributors/causal mechanisms and closely related factors explained in simple terms:
SMARCAD1 skin-isoform variant. A change in the skin-specific version of the SMARCAD1 gene disrupts how the outer skin forms ridges, so fingerprints never appear. PMC
Splice-site mutations. Some changes affect how the gene is cut and stitched (spliced), producing an abnormal protein in skin cells. PMC
Structural variants. Larger DNA changes (rearrangements) in SMARCAD1 can also cause the syndrome. jidinnovations.org
Autosomal dominant inheritance. One altered copy from one parent can be enough to cause the condition. NCBI
De novo mutations. Sometimes the change happens for the first time in the child (not present in either parent). This is uncommon but possible in dominant disorders. (Inference from dominant rare disease genetics, consistent with reports across families.) NCBI
Abnormal ridge development. Fingerprint ridges form before birth; gene changes disturb the shape and depth of these ridges. PubMed
Fewer sweat gland openings on palms/soles. People can have fewer visible pores for sweat, which links to reduced sweating. MalaCards
Keratinocyte growth and patterning changes. Skin cells that build ridges do not follow the normal “blueprint,” so surfaces stay flat or smoothed. (Supported by adermatoglyphia biology and histology reviews.) PMC
Hypohidrosis mechanisms. Changes in the way sweat glands are built or innervated reduce sweat on palms/soles. MalaCards
Neonatal skin fragility on acral skin. Newborn blisters likely reflect fragile top skin layers soon after birth; these heal with time. NCBI
Milia formation. Tiny white cysts form when keratin gets trapped under the skin surface, common in newborns here because of altered skin structure. Orpha.net
Variable expressivity. Symptoms can differ even within a family because the same mutation can have different strength (variable expressivity). (General genetic principle described across Basan families.) PMC
Modifier genes/environment. Heat, friction and individual genetic background can change how noticeable symptoms are (e.g., sweating, fissures). (General inference consistent with reports of variable severity.) NCBI
Overlap with other adermatoglyphia syndromes. Different genes (like KRT14) cause NFJS/DPR with absent fingerprints but extra features; this shows the ridge-building pathway is sensitive to several genes. PMC
Reduced ridge depth after trauma/pressure. Trauma or constant pressure can further smooth ridges in those already lacking them. (Observed widely in adermatoglyphia discussions.) PMC
Embryonic timing. If the pathway is disrupted during the exact window when ridges and pores form, the result is permanent adermatoglyphia. PubMed
Chromatin remodeling defect. SMARCAD1 is involved in DNA/chromatin processes; skin-specific disruption likely alters how ridge-forming genes are turned on/off. (Mechanistic inference aligned with SMARCAD1 function.) PMC
Acral skin biomechanics. The ridges normally improve grip; without ridges, the skin stresses differently, which may contribute to fissures in adults. (Clinical inference consistent with adult fissuring reports.) NCBI
Reduced sweat cooling. Less sweating on palms/soles can worsen heat handling during heavy work or hot weather. Wikipedia
Ultra-rarity and founder effects. Some families share the same mutation (founder mutation), explaining why few lineages are reported worldwide. OUP Academic
Common symptoms and signs
No fingerprints (adermatoglyphia). The classic sign. Ridges on fingers, palms, toes and soles are missing. Identification by fingerprint is not possible. DoveMed
Facial milia in newborns. Tiny white facial bumps appear soon after birth and often fade. They are harmless. Orpha.net
Newborn blisters on hands and feet. Small blisters (acral bullae) heal quickly in infancy. PubMed
Reduced palm/sole sweating (hypohidrosis). Hands and feet may sweat less, sometimes leading to dry, cracked skin and heat intolerance. NCBI
Single transverse palmar crease (in some). Some individuals have a single crease across the palm. Not harmful, but noted in reports. NCBI
Palmoplantar keratoderma (sometimes). Thickened skin on palms/soles can develop over time. NCBI
Nail grooves or nail changes. Grooving or mild nail dystrophy can occur. NCBI
Finger contractures or toe syndactyly (occasionally). Some families report bent fingers (camptodactyly) or fused toes. Wikipedia
Dry or fragile acral skin in adults. Skin on hands/feet may fissure or blister with trauma or friction. NCBI
Thinner or thicker skin areas. Reports mention either thin or thickened skin patches. Wikipedia
Normal general health. Most people are otherwise well; the condition mainly affects skin and sweat function on acral sites. Orpha.net
Heat intolerance in hot weather. Because of reduced sweating, some feel overheated more easily. Wikipedia
Challenges with biometric ID. Lack of fingerprints can complicate passport, visa, and phone or office biometric systems. PMC
Family history across generations. Many cases run in families with an autosomal dominant pattern. NCBI
No increased risk of serious internal disease. Prognosis is usually good; care focuses on skin comfort and heat safety. Wikipedia
How do doctors diagnose it?
Important note: Doctors do not need all 20 tests. They pick a few to confirm the condition and rule out look-alikes. Below are useful tools grouped by category, with simple explanations.
A) Physical examination
Skin and fingerprint ridge check. The doctor looks closely at the fingertips, palms, toes, and soles to confirm absent ridges and pores. This bedside exam is central to diagnosis. PubMed
Facial milia inspection. Tiny white bumps on the face in newborns support the syndrome when paired with absent fingerprints. Orpha.net
Acral blister history and exam. Healed or current blisters on hands/feet in early life point toward Basan syndrome. PubMed
Sweating pattern review. Doctors ask about sweaty vs. dry areas, heat intolerance, and look for dry, cracked acral skin. NCBI
Hair, nails, teeth, and pigmentation check. This helps rule out related KRT14 disorders (NFJS/DPR), which show net-like dark patches, hair and nail changes, and sometimes dental enamel issues. Frontiers
B) “Manual” bedside tests
Ink-and-paper or digital fingerprint capture. Trying to capture prints on ink cards or an electronic scanner demonstrates absent ridges in a simple, low-tech way. PMC
Hand/foot photography under magnification. Close-up photos or dermatoscope images record the lack of ridges and pore openings for the chart. Our Dermatology Online
Minor’s starch–iodine sweat test (qualitative). Iodine is painted and starch is dusted; any sweat turns dark. In hypohidrotic areas (palms/soles here), color change is weak or absent, helping document reduced sweating. Shanghai Chest+1
Water-erasable ink sweat mapping. Simple lines drawn on skin fade with sweat; useful where starch–iodine is impractical. Medical Journals
Hidroscopy with dermoscope. A dermoscope can show sweat duct openings and sweating patterns after a Minor test. JAAD
C) Laboratory and pathological tests
Targeted gene test for SMARCAD1 (skin-isoform). Sequencing looks for known pathogenic variants that cause Basan syndrome. This is the most direct confirmatory test when Basan is suspected. PMC+1
Deletion/duplication analysis / structural variant testing. If sequencing is negative, labs can look for larger changes or complex rearrangements in SMARCAD1. jidinnovations.org
Exome/genome sequencing. Broader testing helps if the picture is unclear or to distinguish from NFJS/DPR (KRT14) or isolated adermatoglyphia. PMC
Skin biopsy (selected cases). Not always required. If done, histology may show features consistent with related reticulate pigmentary disorders and may document ridge flattening or sweat duct changes; it mainly helps to exclude other diseases. Our Dermatology Online
Family segregation study. Testing relatives can show that the same variant tracks with the features in the family, strengthening the diagnosis. (Standard genetics practice for dominant rare diseases.) NCBI
D) Electrodiagnostic / autonomic sweat tests
QSART (Quantitative Sudomotor Axon Reflex Test). Measures sweat produced after mild electrical stimulation with acetylcholine. Reduced response on palms/soles supports hypohidrosis. Cleveland Clinic+1
Sympathetic Skin Response (SSR). Records electrical skin changes tied to sweat gland activation; can complement QSART. ScienceDirect
Autonomic test panels (AFTs). Some centers run a bundle of tests (QSART, heart rate variability, Valsalva, etc.) to document sudomotor function; useful for comprehensive sweat evaluation. Frontiers+1
E) Imaging / digital visualization
High-resolution digital ridge imaging. 2D or 3D scanners visualize ridge absence for the record and for counseling on biometric limitations. PMC
Dermoscopy of sweat ducts (post-stimulation). After heat or pilocarpine, dermoscopy can show few/absent sweat duct openings on palms/soles, aligning with hypohidrosis. JAAD

Dose: As labeled (e.g., 1–10 billion CFU/day). Function: Gut-skin axis support; possible modest anti-inflammatory effects. Mechanism: Microbiome modulation, SCFA production, immune signaling balance.
Immunity-booster / regenerative / stem-cell drugs
There are no FDA-approved “immunity-booster,” regenerative, or stem-cell drugs for Basan syndrome. Experimental stem-cell products marketed for skin “rejuvenation” are not approved for this condition and can be risky. What does help is routine, evidence-based care: up-to-date vaccinations, good wound care, and prompt treatment of infections. If you see offers for stem-cell injections, exosomes, or “regenerative serums” for fingerprints/milia, ask for peer-reviewed evidence and FDA approval—none exists for restoring dermatoglyphs. Orpha.net
Procedures/surgeries
Sterile milia extraction – Tiny nick and expression by a dermatologist for persistent facial milia that bother the patient. Why: Fast relief when conservative care fails.
Curettage of giant/clustered milia – For larger grouped lesions, gentle curettage under local care. Why: Remove keratin cysts safely.
Debridement & advanced dressings for large erosions – Rarely needed after friction blisters. Why: Promote clean granulation and re-epithelialization.
Syndactyly release (if present) – Correct webbed toes that cause shoe problems. Why: Improve function/comfort. NCBI
Nail-fold procedures – For severe nail grooving catching on fabrics. Why: Reduce trauma and snagging.
Prevention tips
Daily bland moisturizer after bathing.
Choose soft, seamless, breathable fabrics for socks/gloves.
Rotate cushioned footwear; use moisture-wicking socks.
Avoid prolonged heat; plan cooling breaks in hot weather. MedlinePlus
Use gentle cleansers; avoid fragrances/harsh solvents.
Sun-protect exposed skin (SPF 30+, hats).

Family genetic counseling before pregnancy to understand inheritance. MedlinePlus
When to see a doctor
Newborn or child with blisters, facial milia, and no fingerprints—for assessment and possible SMARCAD1 testing.
Any spreading redness, yellow crusts, pus, fever, or pain around blisters/fissures (possible infection).
Heat intolerance symptoms: dizziness, headache, nausea during hot weather.
Recurrent, bothersome milia or thickened spots not improving with gentle care.
For letters supporting alternate ID methods at work/school and travel. Orpha.net+1
What to eat & what to avoid
Eat more of:
Hydrating fluids (water; add electrolytes during heat).
Protein-rich foods (fish, eggs, legumes) for tissue repair.
Vitamin C sources (citrus, berries, bell peppers).
Zinc sources (lean meats, beans, nuts).
Omega-3-rich foods (fatty fish, flax/chia).
Limit/avoid:
- Excess alcohol (slows healing, dehydrates).
- Very spicy/salty foods before heat exposure (feel hotter/thirstier).
- Ultra-processed snacks with low micronutrients.
- Fragrance-heavy products around the mouth/face that can irritate skin when eating.
- Any supplement mega-doses without medical advice (toxicity risks).
FAQs
1) Is this dangerous?
Usually no. Health is generally good, but sweating on palms/soles may be reduced, raising heat-intolerance risk. Practical issues with biometric ID are common. Wikipedia
2) Can fingerprints grow later?
No. The absence is congenital and lifelong. People adapt with alternative ID methods. Orpha.net
3) Why did my baby have blisters at birth?
The skin on hands/feet may be more fragile in newborns; friction and minor trauma can cause small blisters that tend to improve with age. Orpha.net
4) Are milia harmful?
They’re harmless keratin cysts and often fade on their own. Persistent ones can be safely extracted by a clinician or treated with gentle retinoids. (Off-label for milia.)
5) Is this the same as “adermatoglyphia”?
Yes—adermatoglyphia means “no dermatoglyphs” (fingerprints). Basan syndrome is a specific form that also includes neonatal blisters and facial milia. Orpha.net
6) What gene is involved?
SMARCAD1 (skin-specific isoform) is the main gene linked to isolated adermatoglyphia/Basan syndrome. PMC+1
7) Is it inherited?
Usually autosomal dominant—a child has a ~50% chance if one parent is affected. A genetics team can advise. MedlinePlus
8) Will my child overheat more easily?
Some people sweat less on palms/soles and should follow a heat-management plan (cooling, hydration, shade). MedlinePlus
9) Can creams “bring back” fingerprints?
No known treatment restores dermatoglyphs. Skincare focuses on comfort and protection. Orpha.net
10) Are stem-cell therapies available?
No approved stem-cell or “regenerative” medicines for this condition. Be cautious with unproven offers. Orpha.net
11) Can retinoid creams help milia?
Yes, retinoids (like tretinoin) can help persistent milia; this is off-label. Use exactly as advised; irritation is common. FDA Access Data
12) What if fingerprint scanning is required at work or travel?
Request alternative ID (photo, PIN, iris/face ID) and carry documentation from your clinician. PMC
13) Will nails or toes be affected?
Some families report nail grooving or toe syndactyly; a foot/hand specialist can advise if it causes problems. NCBI
14) How rare is this?
Extremely rare—only a small number of families worldwide are described. Wikipedia
15) What doctor should we see?
A dermatologist (for skin care, milia, blisters) and medical geneticist (for testing and family counseling).
