Expanding the phenotype of anauxetic dysplasia caused by biallelic NEPRO mutations: A case report
American Journal of Medical Genetics Part A, Volume 191, Issue 9, Page 2440-2445, September 2023., 2023 Abstract The cartilage hair hypoplasia and anauxetic dysplasia (CHH‐AD) spectrum encompasses a group of rare skeletal disorders, with anauxetic dysplasia (ANXD) at the most severe end of the spectrum. Biallelic variants in RMRP, POP1, and NEPRO (C3orf17) have previously been associated with the three currently recognized ANXD types.

Dystopic Os odontoideum: A rare cause of atlantoaxial instability
Journal of Spinal Surgery, 2017 Os odontoideum is a relatively common developmental anomaly of the craniovertebral junction (CVJ), which is usually an incidental finding on spine imaging. But the dystopic variety of os odontoideum is uncommon and can be baleful.

Effect of C1 Single‐door Laminoplasty on Symptomatic Atlas Canal Stenosis
Orthopaedic Surgery, Volume 14, Issue 10, Page 2757-2765, October 2022., 2022 Single‐door laminoplasty combined with atlantoaxial fusion is a safe and simple treatment for symptomatic atlas canal stenosis. Atlas hypoplasia usually developed symptomatic myelopathy due to degenerative factors, mainly atlantoaxial subluxation. Tha is why atlantoaxial fixation and fusion was recommended.

Endoscopic endonasal approach to the craniovertebral junction
World Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 8, Issue 1, Page 16-24, March 2022., 2022 Abstract The surgical approach to lesions of the ventral craniovertebral junction (CVJ) has evolved significantly in the last several years with the advent of endoscopic skull base surgery. Differing pathologies of the CVJ can result in irreducible compression of the cervicomedullary region.
