Basan syndrome or “absence of fingerprints–congenital milia syndrome.” It is an extremely rare, autosomal-dominant ectodermal dysplasia caused by variants in SMARCAD1 and characterized by congenital adermatoglyphia (no fingerprints), neonatal acral blisters, and facial milia; some individuals also have hypohidrosis (reduced sweating), plantar keratoderma, nail grooves, camptodactyly, and occasional toe syndactyly. There is no disease-specific curative therapy; management is supportive and symptom-targeted. jidinnovations.org+3PMC+3Nature+3
Baird syndrome is a very rare, inherited skin condition present from birth. The main feature is no fingerprints (medical term: adermatoglyphia). Many babies also have tiny white facial bumps called milia and blisters on the hands and feet that heal. Some people sweat less than usual (hypohidrosis) and can feel overheated more easily. The condition is autosomal dominant—if a parent has it, each child has a 1 in 2 chance of inheriting it. Scientists have shown that specific changes (variants) in a skin-specific isoform of a gene called SMARCAD1 disrupt normal formation of the skin ridges that make fingerprints. Baird (Basan) syndrome is part of a small “family” of related disorders that includes isolated adermatoglyphia and Huriez syndrome, all linked to changes in the same gene region. PubMed+4Wikipedia+4Orpha.net+4
Basan (Baird) syndrome is a genetic skin condition you are born with. Because of a change in a gene called SMARCAD1, the outer layer of the skin develops differently before birth. As a result, the skin on the fingers and toes does not form the tiny ridges that become fingerprints. Many babies also have small white bumps (milia) and blisters on the hands and feet in the first weeks of life. The blisters usually heal on their own. Some people sweat less than normal (hypohidrosis), which can make them overheat in hot weather. A few have thick skin on the soles (keratoderma), nail grooves, bent fingers (camptodactyly), or webbed toes. Life expectancy is normal. Most care is about protecting the skin, avoiding heat stress, and treating symptoms like blisters or thick skin when they happen. Genetic testing can confirm the diagnosis. PMC+1
Other names
Doctors and genetics resources may use several names for the same condition:
Baird syndrome / Basan syndrome (often used interchangeably)
Absence of fingerprints–congenital milia syndrome
Adermatoglyphia with congenital facial milia and acral blisters
Autosomal dominant adermatoglyphia (when fingerprints are the only consistent finding)
These labels all describe the same core picture: absent fingerprints with early milia and sometimes newborn blisters. Wikipedia+1
Types
There is no rigid “types A/B/C,” but clinicians often group cases across a SMARCAD1-related spectrum:
Isolated adermatoglyphia – absent fingerprints with little else. PMC
Baird/Basan syndrome – adermatoglyphia plus neonatal acral blisters and facial milia; may include reduced sweating and minor nail/hand differences. PMC+1
Huriez syndrome (allelic) – a related but more severe condition (palmoplantar keratoderma, tight/atrophic skin of hands, nail hypoplasia) linked to SMARCAD1 haploinsufficiency and a higher risk of cutaneous squamous cell carcinoma. It’s included here to show the shared gene pathway, not because it is the same diagnosis. PubMed+1
Causes
Although one core cause is known—pathogenic variants in the skin-specific isoform of SMARCAD1—researchers have described different genetic mechanisms for how that change interferes with fingerprint formation. Each item below states the mechanism plainly and shows how it fits the evidence.
Skin-specific SMARCAD1 splice-site variants. Most families have a point mutation at the donor splice site of the alternative exon 1 used only in skin, which disrupts normal mRNA and protein, blocking ridge formation. PubMed
Small point mutations. Single-letter DNA changes at that splice site are enough to cause the syndrome in heterozygous state (one altered copy). PubMed
Large deletions including exon 1 of the skin isoform. Some families have a multi-kilobase deletion that removes this critical first exon, producing the same clinical picture. OUP Academic
Complex structural variants. Rearrangements around the start of the skin isoform can alter expression and cause disease. jidinnovations.org
Autosomal dominant inheritance. One altered copy is sufficient; each child has a 50% chance to inherit it. NCBI
De novo variants. A new change can occur in the egg or sperm, so a child can be the first affected in a family. (General inferences from autosomal-dominant disorders; also consistent with case reports.) PubMed
Reduced or abnormal SMARCAD1 protein in skin. The gene encodes a chromatin-remodeling helicase; altered dosage or structure in skin interferes with programs that build ridges and sweat apparatus. genecards.org
Disrupted epidermal differentiation programs. Studies show SMARCAD1 changes perturb expression of genes needed for epidermal patterning. Wiley Online Library
Allelic heterogeneity across the spectrum. Different types of SMARCAD1 variants (splice-site, deletions) can yield isolated adermatoglyphia, Basan/Baird, or Huriez—explaining variable features. jidinnovations.org
Haploinsufficiency (related condition). In Huriez syndrome, having only one functioning SMARCAD1 copy (haploinsufficiency) drives a more severe phenotype, illustrating how dosage matters; it informs the Basan/Baird mechanism. PubMed
Regulatory (non-coding) disruption. Because the skin isoform uses a special first exon, non-coding changes that alter splicing or promoter activity can cause disease. (Documented by splice-site and exon-level deletions.) PubMed+1
Alternative-exon specificity. The abnormality targets the skin-restricted transcript, explaining why fingerprints (a skin-specific structure) are affected while overall health is usually good. PMC
Eccrine/sweat-related development impact. Hypohidrosis suggests the same pathway also influences sweat gland function during development. (Clinical observation tied to the same gene change.) Orpha.net
Variable expressivity. The same family variant can cause slightly different signs (e.g., more or fewer blisters, nail grooves) across relatives—common in dominant skin disorders. MalaCards
Founder effects in small kindreds. Because only ~10 families have been described, some pedigrees likely share the same ancestral variant. Orpha.net
Chromatin remodeling dependency. SMARCAD1 is an ATP-dependent chromatin remodeler; when its function is altered in skin, genes that guide ridge topography misfire. genecards.org
Complex variant mosaicism (possible). As with many dominant disorders, a parent may have mosaicism, explaining apparently “skipped” generations. (General genetics principle applied; consistent with dominant inheritance.) NCBI
Position effects near 4q22–q23. Genomic context at chromosome 4 can influence SMARCAD1 skin isoform expression; mapping studies localize related phenotypes to this region. OUP Academic
Splice-altering intronic changes beyond the canonical site (rare). Non-canonical intronic variants that still disrupt splicing could theoretically cause the same phenotype; families with atypical splice disruption support this. jidinnovations.org
Gene–environment is not causal. Everyday exposures do not cause Baird syndrome; it is a genetic condition present from conception. (Consensus across genetics resources.) Orpha.net+1
Symptoms and signs
No fingerprints (adermatoglyphia). The skin on the palms and soles lacks the raised ridges that create fingerprints, so fingerprint scanners often fail. Wikipedia
Newborn blisters on hands/feet. Many babies develop fragile blisters on the fingers, toes, or palms/soles that heal. PMC
Tiny facial milia in infancy. Small white bumps (keratin plugs) on the face are common early on. Orpha.net
Reduced sweating (hypohidrosis). People may sweat little, making hot weather harder to tolerate. Orpha.net
Heat intolerance. Because sweating cools the body, some feel overheated easily in warm environments. Wikipedia
Thin or sometimes thickened skin. Reports describe either generally thin skin or areas of thickened skin on pressure points. Wikipedia
Palmar/plantar changes. A single transverse palmar crease and mild keratoderma have been noted in some people. Wikipedia
Nail changes. Subtle nail grooving can appear. Wikipedia
Finger contractures (camptodactyly). Some individuals have slightly bent fingers. Wikipedia
Toe syndactyly (rare). Partial webbing of toes has been reported. Wikipedia
Acral blisters recur with friction. Blisters can reappear at pressure/friction sites. PMC
Normal growth and development. Outside the skin findings, general health is usually good. Wikipedia
Administrative complications. Lack of fingerprints can make identity checks or travel procedures difficult. Wikipedia
Family pattern. Several relatives across generations often show similar skin findings. Orpha.net
Very rare cancer link is to a different syndrome. Elevated skin-cancer risk belongs to Huriez syndrome, not classic Baird; it’s mentioned here only to distinguish conditions within the SMARCAD1 spectrum. PubMed
Diagnostic tests
A) Physical examination
Careful hand/foot inspection. A clinician looks for absent ridges on palms/soles, newborn blisters history, milia, and sweat pattern—often enough to suspect the diagnosis. Orpha.net
Dermatoglyphic assessment. Old-fashioned ink prints or modern optical scans confirm that ridge patterns are missing or severely reduced. Wikipedia
Dermoscopy (skin surface microscopy). A handheld scope magnifies palmar/plantar skin to show absent ridge architecture. (Tool widely used in dermatology; supportive for this condition.) Wikipedia
Nail and digit exam. Doctors look for nail grooves, finger flexion, or toe webbing that sometimes accompany the main features. Wikipedia
Sweat pattern exam. Bedside checks (paper tests or observation) can show little or no sweating in warm conditions. Orpha.net
B) Manual or bedside tests
Fingerprint scanner attempt. Failure of standard scanners despite clean, warm fingers supports adermatoglyphia. (A practical, real-world check.) Wikipedia
Silastic sweat imprint/Thermoregulatory Sweat Test (TST). Simple sweat mapping with indicator powders or capsules shows reduced sweat output. Aetna
Q-sweat (commercial QSART analogue). A standardized, non-invasive measure of sweat production after gentle stimulation. PubMed
Provocation with heat/exercise (observed). Under supervision, mild warming highlights impaired sweating compared with controls. (Part of autonomic test batteries.) PMC
High-resolution photography of palms/soles. Serial images document the stable absence of ridges over time. (Supportive documentation approach in dermatology.) Wikipedia
C) Laboratory & pathological tests
Targeted SMARCAD1 sequencing (skin isoform exon 1 splice site). The key confirmatory test; most families show a splice-site variant in the first exon used in skin. PubMed
Deletion/duplication analysis (e.g., MLPA or CNV calling). Detects larger deletions that remove the skin-specific exon 1. OUP Academic
Whole-exome sequencing. Helpful when targeted tests are negative; has identified new families and complex variants. Nature
Sanger confirmation & segregation. Verifies the variant and checks whether it tracks with the trait in relatives (classic dominant pattern). PubMed
Skin biopsy (selected cases). Usually not required; when done, histology helps rule out other blistering disorders and documents eccrine/surface changes consistent with the phenotype. PMC
Genetic counseling assessment. Documents the 50% recurrence risk for children of an affected individual and discusses testing options. NCBI
D) Electrodiagnostic / autonomic sweat tests
QSART (Quantitative Sudomotor Axon Reflex Test). Measures the volume of sweat produced after a mild stimulus; reduced output supports hypohidrosis. Cleveland Clinic+1
Combined autonomic testing panels. Where available, labs combine QSART/TST to map sweating objectively (useful if heat intolerance is prominent). Aetna
E) Imaging-type skin tools
Reflectance confocal microscopy (if available). A non-invasive “optical biopsy” that can visualize epidermal architecture and show absent ridge patterning; rarely essential but can support the diagnosis. (General dermatology device rationale.) Wikipedia
Standardized dermoscopic/clinical imaging follow-up. Periodic photo-dermoscopic documentation ensures no evolving features suggest a different condition (e.g., Huriez). PubMed

FAQs
1) Is Basan (Baird) syndrome dangerous?
Usually no. Life expectancy is normal. The main risks are heat illness from low sweating and skin problems like blisters or thick skin on the soles. PMC
2) Is there a cure?
No specific cure. Care focuses on skin protection, blister care, and heat safety. PMC
3) Will my child’s milia go away?
Newborn milia usually resolve by themselves in weeks. Persistent lesions later can be treated if desired. NCBI+1
4) Why don’t we have fingerprints?
Changes in SMARCAD1 affect how the skin’s ridges form before birth, so the usual dermatoglyphics never develop. PMC
5) Is it inherited?
Yes—autosomal dominant. A parent with the condition has a 50% chance of passing it on each pregnancy. Genetic counseling helps families plan. Nature
6) Can we confirm the diagnosis?
Yes. Doctors use clinical signs and genetic testing for SMARCAD1 to confirm it. Orpha.net
7) Are there other health problems?
Most people are otherwise healthy. Some have reduced sweating, plantar keratoderma, nail changes, or digit anomalies. PMC
8) How do we prevent blisters?
Reduce friction (good shoes/socks, emollients), drain large tense blisters safely, and protect with non-stick dressings. PMC
9) What about school or sports?
With cooling breaks, hydration, and shade, most activities are fine. Plan ahead in hot weather. PMC
10) Do we need regular specialist care?
Yes—dermatology (and podiatry) check-ups help manage keratoderma and nail issues early. PMC
11) Are retinoid pills a solution?
Only in severe, refractory keratoderma under specialist care. They have serious risks (notably teratogenicity). FDA Access Data+1
12) What if a blister looks infected?
Seek care. Doctors may use topical (e.g., mupirocin) or oral antibiotics depending on severity. Don’t start antibiotics without advice. FDA Access Data+1
13) Can topical retinoids help milia?
Yes, for persistent lesions in older children/adults; they increase skin turnover. Use carefully to avoid irritation. Medscape
14) Do we need to worry about ID systems needing fingerprints?
Yes—lack of fingerprints can complicate biometric identification. Carry alternative ID and documentation about the condition. Wikipedia
15) Is research ongoing?
