Humerofemoral hypoplasia with radiotibial ray deficiency (HHRRD) is a severe dysostosis characterized by reduction of all 4 limbs as well as hypoplasia of the upper limb girdle and pelvis. Rudimentary finger- or toe-like appendages may be present (Szenker-Ravi et al., 2018). [from OMIM]

Tetraamelia syndrome-2 (TETAMS2) is characterized by rudimentary appendages or complete absence of the limbs, usually symmetric, as well as bilateral agenesis of the lungs. There are abnormalities of the pulmonary vasculature and dysmorphic features, including bilateral cleft lip/palate, ankyloglossia, mandibular hypoplasia, microretrognathia, and labioscrotal fold aplasia (Szenker-Ravi et al., 2018). For a discussion of genetic heterogeneity of TETAMS, see 273395. [from OMIM]
