Syndrome that has characteristics of female to male sex reversal and developmental anomalies of the kidneys, adrenal glands and lungs. The syndrome is lethal and has been described in three fetuses. It is caused by homozygous missense mutations in the WNT4 gene. It is transmitted as an autosomal recessive trait.

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.
