About this section

NIH Rare Diseases:42 Aarskog syndrome is an inherited disease that affects a person's height, muscles, skeleton, genitals, and appearance of the face. intellectual development may also be affected. about 20 percent of people with aarskog-scott syndrome have mutations in the fgd1 gene. the cause in other affected individuals is unknown. the condition is inherited in an x-linked recessive pattern. last updated: 9/7/2011

MalaCards based summary: Aarskog-Scott Syndrome, also known as aarskog syndrome, is related to b-cell lymphomas and leukemia, and has symptoms including shawl scrotum, everted lower lip vermilion and hypertelorism. An important gene associated with Aarskog-Scott Syndrome is FGD1 (FYVE, RhoGEF and PH domain containing 1), and among its related pathways are EGFR1 Signaling Pathway and Cytoskeletal Signaling. The compounds Guanosine monophosphate and Guanosine diphosphate have been mentioned in the context of this disorder. Affiliated tissues include bone, skin and testes.

Disease Ontology:9 A monogenic disease affects a person's height, muscles, skeleton, genitals, and appearance of the face.

Genetics Home Reference:22 Aarskog-Scott syndrome is a genetic disorder that affects the development of many parts of the body. This condition mainly affects males, although females may have mild features of the syndrome.

OMIM:46 Aarskog syndrome is characterized by short stature and facial, limb, and genital anomalies. One form of the disorder is... (100050) more...
