Article Abstract
Introduction: X-linked spondyloepiphyseal dysplasia tarda(SEDT) is a type of shorttrunk skeletal dysplasia, occurring in males due to mutation in TRAPPC2 gene.
Case Report: We describe a large Indian family with multiple males affected with X-linked SEDT. The affected individuals presented with disproportionate short stature, short trunk, and barrel-shaped chest. Elder sibs aged 26 years and 31 years had back and hip pain. Premature osteoarthritis was seen requiring hip replacement surgery in one sib. The known pathogenic nonsense mutation c.209G>A (p.W70X) was identified in TRAPPC2 gene. This is the first mutation proven Indian kindred with X-linked SEDT.
Conclusion: Knowledge of molecular basis is essential to provide definitive diagnosis, accurate counseling, and prenatal diagnosis or early postnatal diagnosis for this rare condition.

Spondyloepiphyseal dysplasia tarda (SEDT) is a condition involving late-onset, X-linked recessive skeletal dysplasia caused by mutations in the gene. In this paper, we identified a novel nonsense variant in a SEDT pedigree and analyzed the function of the variant in an attempt to explain the new pathogenesis of the TRAPPC2 protein in SEDT. Briefly, DNA and RNA samples from the peripheral blood of SEDT individuals were prepared.

Rare genetic skeletal disorders (GSDs) remain the major problem in orthopedics and result in significant morbidity in patients, but the causes are highly diverse. Precise molecular diagnosis will benefit management and genetic counseling. This study aims to share the diagnostic experience on a three-generation Chinese family with co-occurrence of spondyloepiphyseal dysplasia (SED) and X-linked hypophosphatemia (XLH), and evaluate the therapeutic effects of two third-generation siblings.

Article Synopsis
- Spondyloepiphyseal dysplasia tarda (SEDT) is a rare genetic disorder affecting the skeleton, and there's limited information on orthopedic surgeries for affected patients, marking this study as a significant first.
- A 31-year-old man, previously misdiagnosed with juvenile idiopathic arthritis, was found to have SEDT with severe spinal issues, ultimately undergoing surgery that included laminectomy and spinal decompression, leading to improved mobility one year later.
- The study emphasizes the importance of early diagnosis and tailored treatment plans for SEDT, advocating for surgical intervention when neurological and joint mobility issues arise.
