Bowen-Conradi Hutterite Syndrome is a very rare inherited condition that affects many parts of a baby’s body before birth and after birth. It belongs to a group of disorders called ribosomopathies—conditions caused by problems in making ribosomes, the tiny machines inside cells that build proteins. In BCS, a change (mutation) in a gene called EMG1 weakens ribosome assembly. When ribosomes do not work well during early development, growth is poor and several organs form abnormally. Sadly, many affected babies die in the first months or first year of life because of severe growth failure, feeding problems, infections, and complications from breathing or neurological issues. monarchinitiative.org+3MedlinePlus+3NCBI+3
Bowen-Conradi Hutterite Syndrome is an autosomal recessive genetic disease. A baby develops it only when both parents carry one changed copy of the EMG1 gene and both pass that changed copy to the child. The best-known change is a single “letter” swap in the gene—called D86G—that is common in Hutterite families because of a founder effect (a distant shared ancestor). This faulty EMG1 blocks normal building of the small ribosomal subunit, so cells cannot make proteins efficiently during early development. The result is severe growth restriction before and after birth, an abnormally small head (microcephaly) that is long and narrow (dolichocephaly), a prominent high-bridged nose, a small lower jaw (micrognathia) and chin, feeding problems, and limb or joint abnormalities such as finger contractures or rocker-bottom feet. Most babies have serious medical challenges from birth and many do not survive beyond infancy. NCBI+3sciencedirect.com+3MedlinePlus+3
Bowen-Conradi syndrome is a very rare inherited disorder in which a change in the EMG1 gene harms how the body builds the small part of ribosomes, the cell’s protein-making machines. Because protein building is basic to growth, babies show very poor growth before and after birth, a very small head (microcephaly), facial and skeletal differences, tight joints, feeding problems, and developmental delay. Most reported cases occur in the North American Hutterite population because of a founder variant, but cases can occur in any group. Sadly, most affected infants die in early life from complications of feeding problems, infections, or breathing issues; care focuses on comfort, nutrition, and preventing complications. pubmed.ncbi.nlm.nih.gov+2orpha.net+2
Other names
Doctors and articles may use several names for the same condition:
-
Bowen-Conradi syndrome (most common)
-
Bowen-Conradi Hutterite syndrome or Bowen Hutterite syndrome (because it is most common in people of Hutterite ancestry in North America)
-
BWCNS (abbreviation sometimes used in genetics resources)
All of these refer to the same disease caused by harmful changes in the EMG1 gene. National Organization for Rare Disorders+
Types
There are no formal medical subtypes of Bowen-Conradi syndrome. Clinicians sometimes use practical labels:
-
“Classic” BCS due to the Hutterite founder variant (EMG1 D86G) – the most commonly reported form, with severe prenatal and postnatal growth failure and high infant mortality. sciencedirect.com
-
Non-founder EMG1 variants – very rare reports outside Hutterite communities where a different EMG1 mutation is found; clinical severity appears similar because the shared mechanism is ribosome assembly failure. (This is rare but biologically consistent with EMG1’s role.) PMC+1
Causes
Although one gene change causes the disease, it helps to spell out the different “cause-level” ideas doctors use—gene, protein, cell, and population levels:

Immunity-booster / regenerative / stem-cell” drugs
There are no approved “immunity-booster” drugs or stem-cell medicines for Bowen-Conradi syndrome. Experimental cell or gene therapies are not established and should only be considered in IRB-approved research, given the underlying global ribosome-biogenesis defect. Safer, evidence-based options that lower infectious risk in fragile infants include: (1) routine vaccinations on schedule, (2) RSV prophylaxis (palivizumab monthly or single-dose nirsevimab if eligible), (3) good nutrition and vitamin D to support general immunity, (4) hand hygiene and sick-contact avoidance, (5) prompt treatment of infections, and (6) influenza and pertussis cocooning for household members. These measures are the only interventions with strong evidence and official labeling that truly reduce severe infections in high-risk infants. FDA Access Data+1

When to see doctors (red-flag list)
See a doctor urgently for any breathing trouble (fast breathing, pulling in at ribs, bluish lips), poor feeding or vomiting with choking, fever in a young infant, dehydration (dry mouth, fewer wet diapers), possible seizures (staring spells, jerks, loss of awareness), sudden lethargy, persistent vomiting, or blood in stools. Regular visits are also needed for growth faltering, reflux not improving, recurrent infections, worsening contractures, or any change in tone or alertness. These signs often precede serious illness in fragile infants, and early care improves outcomes. American Academy of Family Physicians+1
Foods to favor and to avoid
What to eat (guided by SLP/dietitian):
- Energy-dense formula or breast milk fortification per plan, to reach calorie goals safely.
- Appropriate texture-modified feeds (e.g., slightly thick liquids) if recommended after swallow study.
- Frequent, small feeds to lower reflux load.
- Adequate protein sources appropriate for age (formula/breast milk).
- Vitamin D and iron through fortified formula or supplements when prescribed.
- Healthy fats per plan, sometimes including MCT if malabsorption is diagnosed.
- Hydration strategies (measured volumes, ORS during mild illness).
- DHA-containing formulas or maternal DHA intake for breastfeeding.
- Fiber-appropriate purees later in infancy to prevent constipation if safe with swallowing.
- Probiotic-containing foods (age-appropriate) only if clinician approves. NCBI+2Office of Dietary Supplements+2
What to avoid (or use only if cleared by the care team):
- Thin liquids if a swallow study showed aspiration risk.
- Large, fast feeds that worsen reflux.
- Unsupervised thickeners in premature infants.
- Honey in infants <1 year (botulism risk).
- High-choking-risk textures if oral-motor control is poor.
- Cow’s milk as a drink before 12 months (not formula).
- Excess vitamin D or iron beyond prescribed doses.
- Secondhand smoke exposure (worsens reflux and infections).
- Unproven “immune boosters” or stem-cell products marketed online.
- Delayed medical care for fever, breathing issues, or dehydration. Johns Hopkins Medicine+2Office of Dietary Supplements+2
Frequently asked questions
1) What causes Bowen-Conradi syndrome?
A harmful change in EMG1, a gene needed for building the small ribosome subunit. It disrupts protein synthesis during development. PMC
2) Is it inherited?
Yes. It’s autosomal recessive: both parents are typically healthy carriers; each pregnancy has a 25% chance of being affected. orpha.net
3) Is there a cure or disease-specific drug?
No. Care is supportive—nutrition, breathing safety, infection prevention, and comfort. rarediseases.info.nih.gov
4) Do all babies have the same features?
Most share severe growth failure and microcephaly, but facial, skeletal, kidney, and brain findings can vary. NCBI
5) Why are Hutterite families often mentioned?
A founder variant in this community increased cases, but the condition can occur elsewhere. pubmed.ncbi.nlm.nih.gov
6) How is it diagnosed?
By clinical features plus genetic testing for EMG1 variants using targeted single-gene or panel testing. fulgentgenetics.com
7) What is the outlook?
Sadly, most infants die early due to complications. Care aims to maximize comfort and family time. NCBI
8) Can better feeding help?
Yes. Feeding therapy, careful positioning, and tube feeding (NG or G-tube) can improve nutrition and reduce aspiration. ASHA+1
9) Are acid-reducing medicines safe for babies?
They can help selected older infants/children with documented GERD, but are not routine in young infants; use only with specialist guidance and label-based dosing. FDA Access Data+1
10) How can we lower infection risks?
Keep vaccines up to date, practice hand hygiene, and ask about RSV prophylaxis (nirsevimab or palivizumab) if eligible. FDA Access Data+1
11) What therapies help tight joints and bent fingers?
Physical/occupational therapy, splints, and sometimes surgery if function is limited. Orthobullets+1
12) Is pain common?
Pain can occur from reflux, procedures, or contractures; clinicians use careful multimodal comfort strategies. American Academy of Family Physicians
13) Should our family get genetic counseling?
Yes—learn carrier status, recurrence risk, and testing options for future pregnancies. orpha.net
14) What about experimental stem-cell or gene therapy?
There is no established cell or gene therapy; any offer outside a proper clinical trial is not recommended. PMC
15) Where can we read more?
GARD and Orphanet pages provide accessible summaries; primary research describes the EMG1 defect and ribosome biology. rarediseases.info.nih.gov+2orpha.net+2
