≤11 ribs is associated with a number of congenital abnormalities and skeletal dysplasias, including:
- Down syndrome (trisomy 21)
- campomelic dysplasia
- kyphomelic dysplasias
- asphyxiating thoracic dysplasia (Jeune syndrome)
- short rib polydactyly syndromes
- trisomy 18
- chromosome 1q21.1 deletion syndrome
- atelosteogenesis
- spondylocostal dysostosis
- spondylometaphyseal dysplasia, Sedaghatian type
- Ritscher-Schinzel syndrome
However, it is important to note that up to 8% of individuals have been found to have 11 pairs of ribs, as an anatomic variant, without any apparent deleterious clinical sequelae 1.
