What is a common feature of Hypochondroplasia?

Hypochondroplasia is a type of skeletal dysplasia that is characterized by disproportionate short stature. One of its hallmark features includes a stocky build with short stature, which means that individuals with this condition often have a shorter overall height compared to the average population but maintain a relatively proportionate body shape compared to their limbs and trunk. This feature is particularly notable as it distinguishes hypochondroplasia from other forms of dwarfism, such as achondroplasia, which can exhibit more severe disproportionate features.

Individuals with hypochondroplasia typically have shorter limbs and a stockier body type, leading to a phenotype that remains recognizable throughout life. The other options do not align with the typical presentation of hypochondroplasia: severe limb shortening is more characteristic of other conditions, intellectual disability has a lower incidence in hypochondroplasia compared to some other genetic disorders, and the diagnosis is not limited to detection only at birth but can often be made throughout early childhood as growth patterns become evident.
