Presentation
Abstract We present a case of rhizomelic dwarfism with clinical, radiographic and histologic features in keeping with atelosteogenesis type III (spondylohumerofemoral hypoplasia). [ncbi.nlm.nih.gov]
AB - We present 5 cases of a short-limb dwarfism syndrome whose manifestations overlap those of atelosteogenesis and oto-palato-digital syndrome Type II. [jhu.pure.elsevier.com]
As it was present in only 20% of the reads sequenced in this region, we consider that this mutation is presented as mosaic in the patient. [scielo.br]

Distinctive radiographic findings comprise severe platyspondyly, distally tapered; shortened, incomplete or absent humeri and femurs; shortened or bowed radii, ulnas, and tibias; hypoplastic pelvis and fibulas; and deficient ossification of the metacarpals [rareguru.com]

Face, Head & Neck
- Hypertelorism
Craniofacial dysmorphism describes a prominent forehead, hypertelorism, a depressed nasal bridge with a grooved tip, micrognathia and frequently a cleft palate. [malacards.org]
The patient had multiple craniofacial abnormalities at birth, including ocular hypertelorism, a flat nasal bridge, micrognathia and a cleft palate. There was rhizomelic shortness of the limbs and a club-foot. [ncbi.nlm.nih.gov]
Facial features included proptosis, hypertelorism, downslanting palpebral fissures, cleft palate, and retromicrognathia. [experts.umn.edu]
- Short Neck
The trunk is disproportionately short and the spine displays abnormal spinal segmentation with block vertebrae, odontoid hypoplasia, subluxation of C2-C3 and unilateral unsegmented bar. The neck is also short. Scoliosis and lordosis are observed. [ctgt.net]

Treatment
Atelosteogenesis Treatment Market Analysis and Size Published on Nov 21, 2022 About The global atelosteogenesis treatment market is expected to witness significant growth during the forecast period. [issuu.com]
Treatment of Atelosteogenesis The treatment of Atelosteogenesis is not possible. One cannot completely cure the affected person but can get treatments and surgeries done in order to avoid certain side effects and symptoms of the disease. [epainassist.com]
The detailed description of this patient should contribute to earlier diagnosis of this condition; anticipation of the poor prognosis in AO1 is essential for appropriate genetic counseling of the parents and for determining postnatal treatment options [ncbi.nlm.nih.gov]

Prognosis
Our surviving patient further defines the radiographic features of the condition and the natural history and prognosis for physical and intellectual disability. [ncbi.nlm.nih.gov]
Prognosis Prognosis is poor. Death is often due to a combination of pulmonary hypoplasia and tracheobronchomalacia early in life. Visit the Orphanet disease page for more resources. [rareguru.com]

Etiology
We conclude that it is reasonable to consider AT-I and boomerang dysplasia as part of a spectrum, probably reflecting a common etiology. [ncbi.nlm.nih.gov]
Etiology Atelosteogenesis III results from missense mutations or small in-frame deletions in the FLNB gene reported in exons 2-5, 13 and 27-33 resulting in the translation of filamin B protein with altered biochemical properties. [orpha.net]
Etiology Atelosteogenesis I results from heterozygous mutations in exons 2-5 and 27-33 of the gene encoding filamin B ( FLNB ) located to 3p14. [rareguru.com]
