Description : Hypochondroplasia is a autosomal dominant disorder characterized by short-limbed dwarfism,
lumbar lordosis, short and broad bones, and caudad narrowing of the interpediculate
distance of the lumbar spine. It shows some resemblance to achondroplasia, but is
much milder and can be distinguished on clinical and radiographic grounds (Walker
et al., 1971).;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the fibroblast growth factor receptor-3 gene (FGFR3, 134934.0010);
