Autosomal recessive optic atrophy, OPA7 type, is a rare inherited eye and nerve condition that mainly damages the optic nerves—the “cables” that carry visual signals from the eyes to the brain. Children usually develop blurred central vision early in life. Over time, vision can slowly worsen. Eye doctors often see pale optic discs on exam and find a central blind spot (central scotoma) and color-vision problems. Some people also have mild, progressive hearing loss (auditory neuropathy). In a few reports, there are extra-ocular nerve problems (sensorimotor axonal neuropathy) and, rarely, mild thickening of the heart muscle (hypertrophic cardiomyopathy). Orpha.net+2NCBI+2
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
OPA7 happens when a child inherits two faulty copies of a single gene called TMEM126A (one from each parent). The TMEM126A protein sits in mitochondria (the cell’s “power plants”) and helps build part of mitochondrial complex I, which is vital for making energy. When TMEM126A does not work, retinal ganglion cells (the cells that form the optic nerve) are especially vulnerable and slowly die, causing optic atrophy. NCBI+1
Other names
This condition is also called Optic atrophy 7 (OPA7), TMEM126A-related optic atrophy, or Optic atrophy 7 with or without auditory neuropathy. You may also see it listed as Autosomal recessive optic atrophy, OPA7 type. search.clinicalgenome.org+1
Types
Doctors often talk about OPA7 in a few practical ways:
Non-syndromic OPA7 — only the optic nerves are affected (vision problems without other symptoms). preventiongenetics.com
Syndromic OPA7 — vision problems plus extra features such as mild progressive sensorineural hearing loss, peripheral neuropathy, or (rarely) mild hypertrophic cardiomyopathy. Orpha.net+1
By age and severity — most patients present in childhood with severe central vision loss; the course is usually slowly progressive. Orpha.net
By genetic variant — different TMEM126A variants (e.g., nonsense, missense, frameshift, splice) are reported; a recurrent founder change c.163C>T (p.Arg55*) has been described in North African families. Phenotype can vary from isolated optic atrophy to optic atrophy with mild deafness. PMC+2PMC+2
Causes
In OPA7, “causes” are genetic and cellular—not lifestyle triggers. Each item below is a pathway or factor that leads to optic-nerve damage in this disease.
Biallelic TMEM126A pathogenic variants (child inherits two faulty copies). This is the core cause of OPA7. NCBI+1
Nonsense variants (e.g., p.Arg55*): create a stop signal in the gene and truncate the protein, leading to loss of function. PMC
Missense variants: single-letter DNA changes that alter one amino acid and impair protein function. American Academy of Neurology
Frameshift variants: small insertions/deletions shift the reading frame and disrupt TMEM126A. BioMed Central
Splice-site variants: errors at intron–exon junctions misprocess RNA and yield a faulty protein. BioMed Central
Large deletions/structural variants: remove key gene segments and abolish function. (Documented across autosomal optic atrophies, including TMEM126A cohorts.) Frontiers
Defective assembly of mitochondrial complex I (ND4 module): TMEM126A acts as an assembly factor; failure weakens energy production. BioRxiv
Mitochondrial energy failure in retinal ganglion cells (RGCs): RGCs need high ATP; low ATP promotes cell death and optic atrophy. Frontiers
Oxidative stress from impaired complex I increases reactive oxygen species that damage RGCs. Frontiers
Cristae/inner-mitochondrial membrane disturbance: TMEM126A localizes to cristae; disruption harms mitochondrial architecture. Frontiers
Axonal vulnerability of long RGC fibers: long, unmyelinated segments are metabolically demanding and susceptible to mitochondrial defects. Frontiers
Founder effect (population genetics): the recurrent p.Arg55* variant expanded in some North African groups, raising local risk. Frontiers
Consanguinity (parents related): increases the chance a child receives two copies of the same rare variant. (Shown in OPA7 families.) PMC
Compound heterozygosity: two different TMEM126A variants (one on each allele) can cause disease. BioMed Central
Modifier genes/mitochondrial pathways: variation in other mitochondrial genes may influence severity. (General OA evidence.) Frontiers
Auditory nerve susceptibility: similar mitochondrial stress may injure auditory neurons, causing mild hearing loss in some patients. PMC
Peripheral axonal neuropathy mechanisms: energy failure can also affect long peripheral axons in rare OPA7 cases. Orpha.net
Cardiomyocyte metabolic stress (rare): limited reports of mild hypertrophic cardiomyopathy likely reflect mitochondrial compromise. Orpha.net
Reduced TMEM126A expression/function: any mechanism that meaningfully reduces functional TMEM126A protein can lead to disease. NCBI
Global mitochondrial dysfunction in complex I disorders: OPA7 falls within a spectrum where complex I defects preferentially harm RGCs. Frontiers
Symptoms
Blurred central vision that starts in childhood and slowly worsens. Patients struggle with fine detail. Orpha.net
Central blind spot (central scotoma) that makes reading and recognizing faces hard. Orpha.net
Pale optic discs on eye exam (a sign, not felt by the patient, but explains the vision change). Orpha.net
Reduced color vision (especially reds/greens look washed out). Orpha.net

Headaches or eye strain from constant squinting or near work (non-specific but frequent). (General OA descriptions.) BioMed Central
Mild, progressive hearing loss in some patients (auditory neuropathy). PMC
Ringing in the ears (tinnitus) may accompany hearing issues in rare cases. (Auditory neuropathy context.) PMC
Balance or numbness/tingling if peripheral neuropathy is present (rare). Orpha.net
Normal eye structure otherwise (no corneal or lens disease), which helps doctors focus on the optic nerve as the source. Orpha.net
Stable pupils but sometimes abnormal light response if ganglion cell function is reduced. (Optic neuropathy physiology.) BioMed Central
No pain (this is not an inflammatory optic neuritis; it is a degenerative optic neuropathy). BioMed Central
Diagnostic tests
A) Physical exam / bedside eye assessment
Visual acuity testing (distance and near) — checks how well you read letters on a chart; OPA7 shows reduced central sharpness. Orpha.net
Color vision tests (e.g., Ishihara plates) — detect red/green or blue/yellow mistakes typical in optic neuropathies. Orpha.net
Confrontation visual fields — quick bedside screen for central scotomas before formal perimetry. Orpha.net
Pupillary light reflex and RAPD check — assesses optic-nerve function; may be asymmetric if one nerve is worse. (Optic atrophy bedside testing.) BioMed Central
Fundus examination with ophthalmoscope — shows pale optic discs, often temporally, supporting optic atrophy. Orpha.net
B) Manual/functional clinical tests
Automated perimetry (e.g., Humphrey 24-2/10-2) — maps central visual field and documents the central scotoma and progression. Orpha.net
Contrast sensitivity testing — measures ability to see low-contrast targets, commonly reduced in optic neuropathies. (OA literature.) BioMed Central
Color arrangement tests (e.g., Farnsworth D-15) — grade dyschromatopsia beyond screening plates. (OA practice.) BioMed Central
Low-vision functional evaluation — assesses reading speed, face recognition, and daily-living impact to guide aids and accommodations. (Clinical management norms.) BioMed Central
C) Laboratory and pathological tests
Genetic testing of TMEM126A (sequencing + copy-number) — confirms biallelic pathogenic variants (gold standard for diagnosis). preventiongenetics.com
Targeted variant analysis for founder changes (e.g., p.Arg55*) when ancestry suggests higher likelihood. Frontiers
Broader optic atrophy gene panels or exome sequencing — used when the phenotype is suggestive but single-gene testing is negative. preventiongenetics.com
Mitochondrial disease work-up (research/advanced labs) — assays tied to complex I assembly can support the mechanism, though not routinely required. BioRxiv
Rule-out labs (B12, syphilis, toxins) — to exclude other optic neuropathy causes if the history is unclear. (General OA differential approach.) BioMed Central
D) Electrodiagnostic tests
Pattern Visual Evoked Potentials (VEP) — measure signal conduction from retina to brain; latency/amplitude changes support optic-nerve dysfunction. (Hereditary optic neuropathy testing.) BioMed Central
Pattern Electroretinogram (pERG) — assesses ganglion-cell function; reductions support a retinal ganglion-cell/optic-nerve problem. (OA practice.) BioMed Central
Auditory Brainstem Response (ABR) and Otoacoustic Emissions (OAE) — check for auditory neuropathy in patients with suspected hearing issues. PMC
Nerve Conduction Studies/EMG (if neuropathy suspected) — evaluate peripheral sensory-motor axons when symptoms suggest extra-ocular involvement. Orpha.net
E) Imaging tests
Optical Coherence Tomography (OCT) of the retinal nerve fiber layer and ganglion cell complex — shows thinning that matches optic atrophy and helps track change. (Standard in inherited optic neuropathies.) BioMed Central
MRI of brain and orbits (with attention to optic nerves) — usually normal in structure but rules out other causes (tumors, inflammation). In syndromic reports, brain MRI may show nonspecific changes; cardiac echo is considered when cardiomyopathy is suspected. Orpha.net

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+
