Aarskog-Scott syndrome is an inherited disease characterized by short stature, facial abnormalities, skeletal and genital anomalies.

The Aarskog-Scott syndrome (AAS) is also known as the Aarskog syndrome, faciodigitogenital syndrome, shawl scrotum syndrome and faciogenital dysplasia.

Aarskog-Scott syndrome is transmitted in an X-linked recessive manner. The sons of female carriers are at 50% risk of being affected with the syndrome. The daughters of female carriers are at 50% risk of being carriers themselves. Females may have mild manifestations of the syndrome. The syndrome is caused by mutation in a gene called FGDY1 in band p11.21 on the X chromosome.

The syndrome is named for Dagfinn Aarskog, a Norwegian pediatrician and human geneticist who first described it in 1970,[1] and for Charles I. Scott, Jr., an American medical geneticist who independently described the syndrome in 1971.[2]

The Aarskog-Scott syndrome is a disorder with short stature, hypertelorism, downslanting palpebral fissures, anteverted nostrils, joint laxity, shawl scrotum, and mental retardation. The physical phenotype varies with age and postpuberal males may have only minor remnant manifestations of the prepuberal phenotype.
