Definition and Background Information
The Spondylometaphyseal Dysplasia, Sedaghatian Type is a rare and lethal skeletal disorder characterized by severe metaphyseal chondrodysplasia with platyspondyly and limb shortening. It is inherited in an autosomal recessive manner, with mutations in the GPX4 gene identified as the underlying genetic cause. Affected individuals may present with cardiac conduction defects, central nervous system abnormalities, and neonatal lethality, impacting the quality of life significantly. Research efforts are ongoing to understand the disease mechanisms and identify potential diagnostic and therapeutic strategies for this condition.
Genetic Basis of Spondylometaphyseal Dysplasia, Sedaghatian Type
