Meromelia

Excerpt

Meromelia is defined broadly as the partial absence of at least one limb. Limb deficiencies have been known to be caused by chromosomal abnormalities, genetic disorders, environmental exposures in utero, or as a complication of chorionic villus sampling. While "amelia" refers to the complete absence of at least one limb, meromelia is just another form of the same continuum of the disorder based on severity.
