Bruck syndrome 2 is a very rare genetic condition that combines two big problems: (1) bones that break easily (like osteogenesis imperfecta) and (2) tight joints present from birth (congenital contractures). People can have many fractures, short height, curved spine, and clubfeet or bent fingers because the joints are stiff. BRKS2 is inherited in an autosomal recessive way—both parents carry one silent gene change and a child who gets both changed copies is affected. The known cause is harmful changes in a gene called FKBP10, which helps collagen (the main bone protein) fold and cross-link correctly; when FKBP10 does not work, bone is weaker and joints can stiffen even before birth. Orpha.net+2PMC+2
Bruck syndrome 2 is a rare, inherited bone-and-joint disorder where a child is born with joints that cannot fully move and later develops many bone fractures because the body cannot build strong collagen for bone. The problem starts in the womb, continues through childhood, and may need life-long care. The confirmed cause is a harmful change in both copies of the FKBP10 gene, which blocks normal collagen cross-linking and makes bones weak. PMC+1
Bruck syndrome 2 is a genetic bone fragility disorder in which babies are born with tight or fixed joints (contractures) and later develop very fragile bones like osteogenesis imperfecta. It’s caused by changes in the PLOD2 gene, which makes the enzyme lysyl-hydroxylase-2. That enzyme helps cross-link collagen—the “rebar” that gives bone and connective tissues strength. When PLOD2 doesn’t work well, collagen cross-links are weak, so bones fracture easily and joints may be stiff from birth. OUP Academic+3Genetic Diseases Center+3Orpha.net+3
In BRKS2, the FKBP10 protein (also called FKBP65) sits in the cell’s protein factory (endoplasmic reticulum) and supports the preparation of type I collagen. Faulty FKBP10 disrupts special chemical “cross-links” between collagen fibers—especially hydroxylation of certain lysine sites—which leaves bone matrix fragile and leads to repeated fractures and deformity.

Other names
Bruck syndrome type 2
FKBP10-related Bruck syndrome
Osteogenesis imperfecta with congenital contractures (FKBP10 type)
BRKS2 (short form)
These names reflect the same condition and the same FKBP10 gene cause. Orpha.net
Types
Doctors use two genetic types:
Bruck syndrome 1 (BRKS1): due to variants in PLOD2, a gene needed for lysyl-hydroxylase 2, another enzyme that creates collagen cross-links.
Bruck syndrome 2 (BRKS2): due to variants in FKBP10 (FKBP65), a collagen-folding chaperone; this is the focus of this article.
Both types look similar at the bedside: fragile bones plus stiff joints at birth. The different genes act at different steps of the same collagen cross-linking pathway, which explains the shared features. Orpha.net+1
Causes
Because BRKS2 is a genetic disease, “causes” here mean the gene-level changes and related biological effects that lead to the condition, plus family-level factors that raise the chance of inheriting it.
Biallelic FKBP10 variants (loss of function). The essential cause: two harmful FKBP10 changes inherited from carrier parents. OUP Academic
Nonsense or frameshift variants. Early stop signals destroy FKBP10 protein (nonsense-mediated decay). OUP Academic
Missense variants in key domains. Single-letter changes in FKBP10’s protein-folding domains impair activity. OUP Academic
Splice-site variants. Errors in RNA splicing remove or alter critical parts of the protein. OUP Academic
Compound heterozygosity. Two different FKBP10 variants—one from each parent—together cause disease. PLOS
Defective collagen I folding. FKBP10 acts as a chaperone; when it fails, collagen triple helices fold poorly. MedlinePlus
Impaired lysine hydroxylation at collagen telopeptides. FKBP10 dysfunction reduces these key chemical steps, weakening cross-links. PMC
Abnormal collagen cross-link profile. Reduced mature cross-links (pyridinoline) leave bone matrix fragile. PubMed
Endoplasmic reticulum stress. Misfolded collagen builds up, stressing cells that make bone (osteoblasts). PMC
Reduced collagen secretion. Faulty processing lowers the amount of collagen leaving the cell. PMC
Secondary low bone mineral density. Weak matrix fails to mineralize well. PMC
Fetal akinesia-related joint contractures. Stiff joints can reflect low movement in the womb due to connective-tissue weakness. PMC
Autosomal recessive inheritance in carrier couples. Each pregnancy has a 25% chance to be affected. Orpha.net
Consanguinity (parents related by blood). Increases the chance both carry the same rare FKBP10 variant. onlinelibrary.wiley.com
Allelic heterogeneity. Many different FKBP10 mutations have been reported worldwide. onlinelibrary.wiley.com
Founder variants in some populations. Certain communities share the same recurrent variant. PMC
Overlap with recessive osteogenesis imperfecta. FKBP10 variants can cause a spectrum from “pure” OI to BRKS2. OUP Academic
Modifier genes/pathways. Variation in collagen-cross-link enzymes (e.g., PLOD2 pathway) may modify severity. PMC
Post-zygotic variability and environment. While not causal, nutrition and rehab can change how severe bones and joints appear. (Inference from clinical reviews.) PMC
Rare atypical presentations. Some FKBP10-related patients lack obvious congenital contractures early on, showing the same root cause with a different look. PMC
Common symptoms and signs
Frequent bone fractures. Breaks can follow minor bumps because bone is fragile. PMC
Congenital joint contractures. Elbows, knees, ankles, or fingers may not straighten fully from birth. Orpha.net
Clubfoot (talipes). Feet turn inward/down because ankles are tight and tendons are short. PMC
Short height. Repeated fractures and bowed legs slow growth. PLOS
Spinal curvature (kyphoscoliosis). Weak vertebrae and muscle imbalance curve the spine over time. PMC
Bone deformities. Long bones can bow; old fractures may heal crooked. PMC
Joint stiffness and limited range. Daily tasks are hard because joints cannot fully bend or straighten. Orpha.net
Muscle weakness/deconditioning. Pain and casts reduce activity; muscles lose strength. (Clinical inference consistent with reviews.) PMC
Delayed motor milestones. Sitting, standing, and walking may start late due to fractures and stiffness. PMC
Pain. Bone pain from fractures and joint pain from contractures are common. PMC
Respiratory issues. A curved spine and small chest can reduce lung space and cause breathing problems. PMC
Osteopenia/low bone density. Scans show thin bones even between fractures. PMC
Facial/dental changes in some. Some have dentin problems or facial features like in OI; not in everyone. PMC
Skin or ligament changes are uncommon. Unlike Ehlers-Danlos, extreme skin stretchiness is not typical. (Differential noted across series.) PMC
Wide variability. Some children fracture often; others have fewer fractures but more severe contractures. onlinelibrary.wiley.com
Diagnostic tests
A) Physical exam
Full musculoskeletal exam. The doctor gently checks joint positions, range of motion, limb alignment, spine shape, muscle bulk, and pain points. This helps map where contractures and deformities exist and where fractures might have occurred. PMC
Growth and body measurements. Height/length, arm-span, head size, and chest size are charted; slow growth or a small chest may point to severity and guide nutrition and therapy needs. PMC
Gait and functional observation. Watching how a child sits, stands, and walks shows the impact of joint stiffness and bowed bones and guides bracing or therapy plans. PMC
Respiratory and spine assessment. Listening to the lungs and measuring rib cage motion identify breathing limits from spine curvature or chest wall deformity. PMC
B) Manual/bedside tests
Goniometry (joint angle measurement). A simple protractor tool measures how far each joint moves; it tracks progress after therapy or surgery. PMC
Manual muscle testing. The clinician grades muscle strength against gentle resistance; weakness may be secondary to immobilization or pain. PMC
Functional walk test (e.g., 6-minute walk). This safe hallway test estimates endurance and the effect of braces or rods on mobility. PMC
Contracture pattern mapping. Documenting which joints are fixed (e.g., elbows, knees, ankles) helps distinguish BRKS2 from other conditions with loose joints. PMC
C) Laboratory & pathological tests
Genetic testing—FKBP10 sequencing/panel. Confirms BRKS2 by finding two harmful FKBP10 variants; many labs include FKBP10 and PLOD2 on brittle-bone/contracture panels. Orpha.net
PLOD2 testing (to separate BRKS1). If FKBP10 is negative but features fit Bruck syndrome, testing PLOD2 clarifies the type. Orpha.net
Collagen analysis from skin fibroblasts (specialized). Lab studies look at collagen folding and cross-links; in FKBP10 disease, telopeptide lysine hydroxylation and mature cross-links are reduced. PMC+1
Bone turnover markers. Blood/urine tests (e.g., alkaline phosphatase, P1NP, CTX) help monitor bone formation/resorption and response to treatment. (Supportive, not diagnostic alone.) PMC
Calcium, phosphate, vitamin D. Rule out additional metabolic bone problems that could worsen fragility; these do not cause BRKS2 but are useful to optimize care. PMC
ER stress or proteostasis markers (research settings). Some centers study misfolded collagen and stress pathways to understand severity; this is not routine clinical care. PMC
D) Electrodiagnostic tests
Electromyography (EMG). Usually normal in BRKS2; used to exclude nerve or muscle diseases that also cause contractures or weakness. PMC
Nerve conduction studies (NCS). Helps rule out peripheral neuropathy if weakness seems out of proportion; again, BRKS2 is primarily a connective-tissue disorder. PMC
E) Imaging tests
Skeletal survey X-rays. A set of bone images checks for acute and healed fractures, bowing, vertebral compression, and bone shape typical of brittle bone disorders. PMC
Spine radiographs. Measure scoliosis/kyphosis angles to plan bracing or rods and to monitor progression over time. PMC
Dual-energy X-ray absorptiometry (DXA). Low-dose scan that measures bone density (BMD); children with BRKS2 usually have low BMD. PMC
MRI (selected areas). Shows stress fractures, joint structures, and growth plates without radiation; helpful for pre-surgical planning in deformed bones. PMC

All are adjuncts, not BRKS2 disease-modifiers. FDA Access Data
Evidence note: Systematic and cohort studies in pediatric OI show bisphosphonates improve bone mineral density and reduce fracture rates; these data underpin many BRKS2 decisions, with careful extrapolation. onlinelibrary.wiley.com+1
Dietary molecular supplements (adjuncts, not cures)
Discuss every supplement with your specialist—some interact with medicines or are unnecessary if levels are normal.
Vitamin D3 (cholecalciferol) — Supports calcium absorption and mineralization; correct deficiency per blood tests; typical pediatric regimens are individualized by level/age. Avoid excess. NCBI
Calcium (diet or supplement) — Meet age-based requirements to supply bone matrix; split doses with food; avoid co-administration with oral bisphosphonates. FDA Access Data
Protein (including collagen-rich foods) — Provides amino acids (glycine, proline, lysine) for collagen backbone; prioritize whole-food protein; powders only if diet is insufficient. NCBI
Vitamin C — Cofactor for collagen hydroxylation; deficiency impairs collagen; meet recommended intake with fruit/veg. Avoid megadoses without need. Wikipedia
Magnesium — Bone mineral component and enzyme cofactor; supplement only if low; excess causes diarrhea and interacts with some meds. NCBI
Vitamin K (esp. K2 MK-7) — Involved in osteocalcin carboxylation; evidence in pediatric fragility is limited; discuss risks/benefits. NCBI
Phosphate (dietary balance) — Severe deficiency impairs mineralization; correct only if lab-proven; avoid chronic high-phosphate junk foods. NCBI
Zinc — Supports growth and collagen enzymes; supplement if deficient on labs; foods first (meat, legumes). NCBI
Omega-3 fatty acids — May reduce inflammation and help pain modulation; use food sources (fish) or pediatric-safe oils if advised. NCBI
Multivitamin (age-appropriate) — Safety net when appetite is poor; avoid double dosing fat-soluble vitamins. NCBI
Immunity-booster / regenerative / stem-cell drugs
No FDA-approved “stem cell drugs” exist for BRKS2, and the FDA warns against unapproved stem-cell offerings. Experimental mesenchymal cell transplants have been explored in severe OI under trials, but routine use in children with BRKS2 is not established. Discuss only within IRB-approved research settings. NCBI
Teriparatide is an anabolic medicine for adults with severe osteoporosis; generally not used in children with open growth plates. FDA Access Data
Romosozumab has cardiovascular warnings and adult-only labeling. FDA Access Data
Denosumab is not approved in pediatrics and carries serious hypocalcemia/rebound risks—specialist-only consideration. FDA Access Data
For “immunity boosting,” focus on vaccination, nutrition, sleep, and infection prevention—not unproven drugs. NCBI
(Because recommending unapproved “stem-cell drugs” would be unsafe and misleading, I’m deliberately not listing six named products here. If you’re exploring research participation, I can help summarize current trial designs and inclusion criteria.)
Surgeries (procedures & why they’re done)
Intramedullary rodding of long bones (e.g., Fassier-Duval)
Why: Prevent repeated fractures/deformity in femur/tibia; enable mobility.
What happens: Telescoping or fixed rods stabilize the bone internally; often staged with growth. NCBICorrective osteotomies
Why: Realign bowed or malunited bones to restore function and reduce pain.
What happens: Bone is cut and straightened; internal fixation maintains alignment. NCBISpinal fusion for progressive scoliosis
Why: Prevent worsening deformity that threatens lung function or seating balance.
What happens: Instrumentation and fusion of spinal segments; modern techniques improved outcomes alongside stronger bones from medical therapy. NCBITendon releases around contracted joints
Why: Improve range and function when severe congenital contractures limit care or mobility.
What happens: Lengthening/release of tight tendon units with careful rehab afterward. Orpha.netFracture fixation (selected cases)
Why: Stabilize complex fractures that won’t hold in a cast or threaten alignment.
What happens: Minimally invasive fixation chosen to respect fragile bone. NCBI
Preventions (day-to-day)

New limb pain/deformity or inability to bear weight (possible fracture).
Fever, chest pain, severe cough, or breathing difficulty (risk with chest deformity).
Sudden back pain or posture change (vertebral fracture).
After any significant fall or if a cast/splint causes swelling, numbness, or color change.
Poor feeding, weight loss, or severe constipation/vomiting during therapy cycles. NCBI
What to eat and what to avoid
Eat: Dairy or fortified alternatives for calcium; oily fish/egg yolk for vitamin D; lean meats/legumes for protein and zinc; fruits/vegetables for vitamin C/K; whole grains and nuts for magnesium. NCBI
Avoid/limit: Sugary drinks/ultra-processed foods (low nutrient density); excessive salt (urinary calcium loss); excessive caffeine; smoking exposure; alcohol in teens/adults (bone loss); megadoses of supplements without medical need. NCBI
FAQs
Is BRKS2 the same as osteogenesis imperfecta?
No. It overlaps with OI (fragile bones) plus congenital contractures and is specifically caused by PLOD2 variants affecting collagen cross-linking. Genetic Diseases CenterCan medicines cure BRKS2?
No cure yet. Anti-resorptives (like pamidronate) can strengthen bone and reduce fractures in OI and may help BRKS2, but therapy is individualized. PMCAre bisphosphonates approved for children with BRKS2?
No—use is off-label and based on OI evidence; centers follow strict protocols and monitoring. onlinelibrary.wiley.comWhy not use teriparatide in kids?
Labels restrict teriparatide to specific adult osteoporosis groups; not indicated in growing children due to safety concerns. FDA Access DataIs denosumab an option?
It’s not approved in pediatrics; there are risks of severe hypocalcemia and rebound effects. Only experts may consider it in exceptional cases. FDA Access DataWhat surgeries help most?
Intramedullary rodding and corrective osteotomies reduce fractures and deformity; spinal fusion for progressive scoliosis. NCBIWill braces or orthoses weaken muscles?
Used correctly, they support bones and joints while therapy builds strength—goal is safe function, not immobilization. NCBIIs pool therapy safe?
Yes, in a supervised program—water off-loads fragile bones while allowing active movement. NCBIDo we need genetic testing?
Helpful to confirm PLOD2 and guide family planning; it doesn’t change day-to-day care immediately but supports long-term planning. Genetic Diseases CenterCan diet replace medicines?
No. Diet supports bone health; it doesn’t replace medical/surgical care when indicated. NCBICould “stem-cell therapy” fix this?
Not approved for BRKS2; avoid unregulated clinics. Consider only within legitimate, ethics-approved research. NCBIHow often do we check bone density?
Your team sets intervals (e.g., every 12–24 months) based on age, treatment, and fracture history. onlinelibrary.wiley.comWhat about teeth and hearing?
Classic OI features may be less prominent in BRKS2, but routine screening is sensible—plans are personalized. Orpha.netWhy are safe-handling techniques so strict?
Because bending/torsion can fracture bones; training prevents avoidable injuries. NCBIWhat outcomes can we expect?
With a coordinated program (therapies, anti-resorptives when appropriate, and surgery if needed), many children achieve better mobility, fewer fractures, and improved quality of life. PMC
