Micromelic dysplasia–dislocation of radius syndrome is a genetic bone-growth disorder. Babies are born with very short arms and legs and with abnormal shaping of some long bones. One or both elbow joints often form abnormally, and the top of the radius (the radial head) may be out of place (dislocated) from birth. Many children also have a typical facial look—a broad or low nasal bridge, up-tilted (anteverted) nostrils, a long philtrum, and a small chin. Some have short first hand bones, tight elbows or knees, and occasionally hernias or genitourinary differences. Intelligence is usually normal, but some children—more often in the recessive form—can have developmental delay. The condition is very rare and may be inherited in a recessive way (both parents quietly carry a gene change) or in a dominant way (a single changed copy is enough), depending on the subtype. POSNA+4Orpha.net+4National Organization for Rare Disorders+4
Omodysplasia is a rare genetic bone growth disorder. Babies are born with very short arm and leg bones, a distinctive face, and often a dislocated radial head at the elbow (so the radius bone does not line up with the humerus and ulna). The short limbs are why older papers called it “micromelic dysplasia.” The elbow problem explains “dislocation of the radius” in the older name. Orpha.net+1
Other names
You can find the same condition described with these names in medical sources:
Omodysplasia (umbrella name) and Autosomal recessive omodysplasia (OMOD1).
Autosomal dominant omodysplasia (OMOD2).
Micromelic dysplasia, congenital, with dislocation of radius (historic/clinical synonym).
These labels reflect the same clinical picture, with differences in inheritance and typical bone involvement. Orpha.net+2NCBI+2
Types
- Autosomal recessive omodysplasia (OMOD1).
Usually the whole limbs are more severely short (generalized micromelia). Facial traits are typical. Gene studies commonly point to GPC6, a gene that helps control growth-factor signaling around developing bones. Both parents are usually healthy carriers. Monarch Initiative+1 - Autosomal dominant omodysplasia (OMOD2).
Typically upper-limb changes are more prominent (short humeri, short first metacarpals) and congenital radial head dislocation is common. Many families show a single-gene change in FZD2, which sits in the Wnt signaling pathway that shapes limbs before birth. A new (de novo) change or an inherited change can cause it. MedlinePlus+3MalaCards+3PMC+3
Causes
Pathogenic variants in GPC6 (OMOD1). Faults in the GPC6 gene disturb how growing bone cells “sense” and shape growth-factor gradients, producing short, club-like long bones. Monarch Initiative+1
Loss-of-function effects in GPC6. Truncating or disruptive variants reduce or disable glypican-6, impairing cartilage template shaping. Monarch Initiative
Compound heterozygosity in GPC6. Two different harmful GPC6 variants—one from each parent—can combine to cause disease. NCBI
FZD2 variants (OMOD2). Single harmful changes in FZD2 alter Wnt receptor activity and downstream patterning of the limbs. PMC
Dominant negative or haploinsufficiency in FZD2. Some FZD2 changes lower effective receptor levels or interfere with normal receptors. Wiley Online Library
Disturbed Wnt/planar-cell-polarity signaling. Limb bud cells need coordinated Wnt signals for correct length and joint shape; disruption shortens bones and affects elbows. The Journal of Experimental Biology
Abnormal joint cavitation and modeling at the elbow. Early joint-forming steps can misfire, predisposing to congenital radial head dislocation. POSNA+1
Family history consistent with recessive inheritance. Consanguinity or multiple affected siblings can indicate OMOD1. Wiley Online Library
De novo dominant variants. A child can be the first in a family with OMOD2 if a new FZD2 change arises in the egg or sperm. PMC
Modifier genes and background. Differences in other pathway genes may influence how short the limbs become. (Inference consistent with variability across cases.) Wiley Online Library
Prenatal growth-plate signaling imbalance. Cartilage growth plate cells need tightly balanced cues; imbalance shortens and reshapes long bones. NCBI
Abnormal metaphyseal development. The metaphysis widens or forms abnormally in some patients, contributing to limb disproportion. GARD Info Center
Primary elbow ossification anomalies. Abnormal capitellum/radial head shapes predispose the radial head to mal-alignment. PMC

Extremely low population frequency. Rarity raises diagnostic difficulty and delays, not cause per se, but explains why families often lack local awareness. Orpha.net
Symptoms and signs
Short limbs from birth (micromelia). Arms and legs are clearly shorter than expected; in OMOD1 the shortening is usually more generalized and severe. This causes obvious disproportion and short stature. NCBI
Short upper arms (short humeri). The upper arm bone is notably short; this is prominent in OMOD2. Children may struggle to reach overhead or across the body. MalaCards
Short first metacarpals (thumb side hand bones). The bone at the base of the thumb is shortened, changing hand proportions and sometimes thumb function. MalaCards
Congenital radial head dislocation. The top of the radius is out of position at the elbow from birth—often on both sides. Many children have little pain early on but do have limited rotation (turning the palm up/down). POSNA+1
Restricted elbow movement. Stiffness or limited extension/rotation arises from abnormal joint shapes and long-standing dislocation. POSNA
Characteristic facial features. These can include a broad/depressed nasal bridge, anteverted nares, long philtrum, and small chin; they help clinicians recognize the syndrome pattern. NCBI
Short nose with depressed bridge. The bridge of the nose looks low and broad; the tip may be short. MalaCards
Anteverted nostrils. The nostrils point slightly upward, contributing to the distinct profile. MalaCards
Long philtrum. The groove between nose and upper lip appears long or prominent and is a useful facial clue. MalaCards
Small chin (micrognathia). A small or receding chin may be present, occasionally affecting bite alignment. MalaCards
Knee tightness or limited motion. Lower-limb involvement can restrict kneeling or squatting, especially in OMOD1. ResearchGate
Hernias. Some children develop umbilical or inguinal hernias due to connective tissue laxity or abdominal wall differences. MalaCards
Genitourinary anomalies. Findings can include cryptorchidism (undescended testes) or other differences, more often reported in OMOD2 series. MalaCards
Occasional congenital heart defects. A minority of reports mention heart anomalies, so screening is often prudent. MalaCards
Variable developmental delay (more in OMOD1). Most children have typical cognition, but some with the recessive form have delays, so early developmental assessment helps. Wiley Online Library
Diagnostic tests
A) Physical examination
Whole-body dysmorphology exam. A pediatric dysmorphology exam documents limb proportions (upper vs lower segment), joint ranges, hand/foot structure, and facial features to recognize the omodysplasia pattern. NCBI+1
Elbow assessment. The clinician measures flexion/extension and forearm rotation (pronation/supination). Congenital radial head dislocation typically reduces rotation and produces a posteriorly prominent radial head. POSNA+1
Hand examination. Checking the first metacarpal length and thumb positioning helps support OMOD2. Grip and pinch are observed for function. MalaCards
Gait and lower-limb exam. Hip, knee, and ankle alignment and motion are assessed, because generalized limb involvement is common in OMOD1. NCBI
Systemic screening in clinic. A basic cardiac, abdominal, and genitourinary check looks for hernias or organ anomalies sometimes reported with omodysplasia. MalaCards
B) Manual/bedside tests
Functional reach and activity testing. Simple tasks (reaching overhead, turning a doorknob, feeding) reveal the real-world impact of elbow limitations and short upper limbs. POSNA
Limb segment measurements. Measuring upper-arm and forearm lengths over time tracks growth and helps distinguish rhizomelic vs mesomelic patterns. isds.ch
Beighton or laxity check (targeted). While not a laxity disorder, targeted ligament checks around elbows/wrists help document joint stability in the presence of dislocation. (Clinical rationale in skeletal dysplasia assessment.) PMC
Developmental screening tools. Age-appropriate screens (e.g., gross/fine motor) identify children who need early therapy—especially relevant in recessive cases. Wiley Online Library
C) Laboratory and pathological
Targeted genetic testing (single-gene). If the phenotype points strongly to OMOD2 or OMOD1, testing FZD2 (dominant) or GPC6 (recessive) can confirm the diagnosis. NCBI+1
Skeletal dysplasia gene panel. When the picture is less specific, a multi-gene panel for skeletal dysplasias increases the chance of a clear answer. Medscape
Exome/genome sequencing. Broad sequencing is useful if panel testing is negative or to detect unusual or de novo variants. (Standard approach in rare genetic dysplasia work-ups.) NCBI
Chromosomal microarray (CMA). CMA looks for larger deletions/duplications if sequencing does not find a variant but suspicion remains. (General rare disease workflow.) NCBI
Parental segregation studies. Testing parents clarifies recessive inheritance (two carriers) or confirms a de novo dominant variant—key for recurrence counseling. NCBI
D) Electrodiagnostic
Nerve conduction studies (selective). These are not routine for omodysplasia but can rule out peripheral nerve problems if hand weakness seems greater than expected from bone differences. (Differential work-up principle.) Medscape
Electromyography (EMG) (selective). EMG is reserved for atypical cases with suspected neuromuscular overlap; it is usually normal in pure skeletal dysplasia. (General dysplasia guidance.) PMC
E) Imaging
Plain radiographs of elbows. AP/lateral elbow X-rays show the shape of the radial head and capitellum and confirm congenital dislocation (often posterior), the most common congenital elbow anomaly. Radiopaedia+1
Hand/wrist X-rays. Films document short first metacarpals and other pattern clues that support OMOD2. MalaCards
Skeletal survey. A full set of bone X-rays maps overall limb shortening, metaphyseal changes, and other features to separate omodysplasia from look-alike dysplasias. isds.ch
Prenatal ultrasound / fetal imaging (when relevant). In families with a known variant, targeted fetal imaging can detect abnormal limb lengths and joint shapes; genetic testing can confirm. (General practice in genetic skeletal dysplasias.) NCBI

FAQs
1) Is “micromelic dysplasia with dislocation of radius” the same as omodysplasia?
Yes—older sources used that name; today we usually say “omodysplasia,” with OMOD1 (recessive, GPC6) and OMOD2 (dominant, FZD2). Orpha.net+1
2) Will medicines fix the bone problem?
No medicine changes the genetic bone patterning. Drugs only help with pain, surgery comfort, or associated issues. Therapy and selective surgery drive function. Orpha.net+1
3) Do all children need surgery?
No. Many manage well with OT/PT, splints, and adaptations. Surgery is considered for significant pain, function limits, or progressive deformity. NCBI+1
4) Which elbow surgery is most common later on?
For painful, chronically dislocated radial heads in skeletally mature patients, radial head excision can help selected cases. NCBI
5) Can the elbow be “put back” in young children?
Sometimes, with ulnar osteotomy and ligament reconstruction in specific anatomies and ages; results vary and need expert evaluation. NCBI
6) Is the dislocation usually posterior?
Yes; posterior is most common, though anterior and lateral occur. It is often bilateral. Radiopaedia
7) What specialists should be on the care team?
Pediatric orthopedics/hand surgery, OT/PT, genetics, primary care, and (when needed) pain/pediatric rehab medicine. OrthoInfo
8) How is the diagnosis confirmed?
By clinical/radiographic features plus genetic testing (GPC6 or FZD2, depending on pattern). NCBI+1
9) Will my child’s thinking be affected?
Most children have typical cognition; needs are physical/functional. Some reports note associated findings; each child is different. MalaCards
10) Are there braces that help?
Yes—custom splints for wrist/forearm and activity braces for the elbow can reduce pain and protect motion. assh.my.site.com
11) Do growth spurts make things worse?
Symptoms can fluctuate with growth; regular follow-up catches changes early. NCBI
12) Are there experimental gene or stem-cell cures?
No established therapies yet; avoid unregulated “stem-cell” offers. Consider clinical trials only through reputable centers. Orpha.net
13) What about radial club hand—how is it related?
Some children have features overlapping radial longitudinal deficiency (radial club hand). Principles of alignment, distraction, and tendon balancing may apply. PMC+1
14) Can diet help?
Diet does not change genes but supports bone and recovery—ensure vitamin D, calcium, protein, and overall balanced nutrition. Office of Dietary Supplements+1
15) Where can families learn more?
Authoritative overviews are available from Orphanet, NIH GARD, and pediatric hand societies. Orpha.net+2GARD Info Center+2
