A rhizo-mesomelic dysplasia with characteristics of rhizomelic short stature in combination with lateral clavicular defects. Additional manifestations include brachydactyly with bilateral clinodactyly and hypoplastic middle phalanx of the fifth digit. The syndrome has been reported in one family (mother and son) and is suspected to be transmitted in an autosomal dominant manner. There have been no further descriptions in the literature since 1988.

Tetraamelia syndrome-1 (TETAMS1) is characterized by complete limb agenesis without defects of scapulae or clavicles. Other features include bilateral cleft lip/palate, diaphragmatic defect with bilobar right lung, renal and adrenal agenesis, pelvic hypoplasia, and urogenital defects (Niemann et al., 2004). Genetic Heterogeneity of tetraamelia syndrome Tetraamelia syndrome-2 (TETAMS2; 618021) is caused by mutation in the RSPO2 gene (610575) on chromosome 8q23.
