Summaries for Alpha-Thalassemia X-Linked Intellectual Disability Syndrome

About this section


NIH Rare Diseases:41 Alpha-thalassemia x-linked intellectual disability (atrx) syndrome is a genetic condition that causes intellectual disability, muscle weakness (hypotonia), short height, a particular facial appearance, genital abnormalities, and possibly other symptoms.  it is caused by mutations in the atrx gene and is inherited in an x-linked way.  treatment includes regular visits to the doctor to monitor growth and intellectual development, early intervention and special education programs, and special formula to help with feeding and nutrition. last updated: 10/3/2012

MalaCards based summary: Alpha-Thalassemia X-Linked Intellectual Disability Syndrome, also known as atr-x syndrome, is related to mental retardation and thalassemia, and has symptoms including cryptorchidism, male pseudohermaphroditism and ambiguous genitalia. An important gene associated with Alpha-Thalassemia X-Linked Intellectual Disability Syndrome is ATRX (alpha thalassemia/mental retardation syndrome X-linked). Affiliated tissues include kidney, testes and tongue.

Genetics Home Reference:21 Alpha thalassemia X-linked intellectual disability syndrome is an inherited disorder that affects many parts of the body. This condition occurs almost exclusively in males.
