Fragile X Syndrome Macroorchidism
Fragile x syndrome macroorchidism. Fragile X syndrome is caused by the expansion or lengthening of the FMR1 gene on the X chromosome known as a gene mutation. When the gene lengthens it switches off production of a protein that is involved in brain development and other functions. Fragile X syndrome is a genetic disorder caused by an abnormality in a gene on the X chromosome with more severe symptoms in males and is characterized by intellectual disability language delays behavioral problems autism or autistic-like behavior including poor eye contact and hand-flapping enlarged external genitalia macroorchidism.
Early skeletal symptoms may. The following is a list of genetic disorders and if known type of mutation and for the chromosome involved. Fragile X syndrome is an X-linked dominant disorder with incomplete penetrance characterized by large ears and jaws macroorchidism and varying degrees of mental deficiency in affected males.
McCune-Albright syndrome MAS is a disorder that affects the skin skeleton and certain endocrine organs hormone-producing tissues. Enlarged pinna macroorchidism. The X chromosome is one of two sex-determining chromosomes.
Deformities of auricle or external ear canal. FMR1 disorders include fragile X syndrome FXS fragile X-associated tremorataxia syndrome FXTAS and fragile X-associated primary ovarian insufficiency FXPOI. Cafe-au-lait spots of the skin are common and are usually the first apparent sign of MASThe main skeletal feature is fibrous dysplasia which ranges in severity and can cause various complications.
Mental retardation cerebral palsy hearing loss. Although the parlance disease-causing gene is common it is the occurrence of an abnormality in the parents that causes. Fragile X syndrome occurs in individuals with an FMR1 full mutation or other loss-of-function variant and is nearly always characterized in affected males by developmental delay and intellectual disability.
The mental deficiency may be extremely subtle or manifest solely as autism.
The X chromosome is one of two sex-determining chromosomes.
