Summary

Bent bone dysplasia syndrome-2 (BBDS2) is characterized by defects in both the axial and appendicular skeleton, with radiographic findings of undermineralized bone and a distinct angulation of the mid femoral shaft. Extraskeletal features include facial dysmorphisms, abnormally formed ears with tags, widely spaced nipples, and atrial septal defects. Abnormalities of muscle function are suggested by the presence of elbow fusions, ulnar flexion contractions at the wrist, and bilateral talipes equinovarus, as well as failure to mount a respiratory effort at birth (Barad et al., 2020). For a general phenotypic description and discussion of genetic heterogeneity of bent bone dysplasia syndrome, see BBDS1 (614592). [from OMIM]
