What is Med 12 associated syndrome?
What is Med 12 associated syndrome?
The mediator complex subunit 12 gene (MED12) is responsible for an X-linked recessive intellectual disability syndrome that is characterized by dysmorphic features such as a long, narrow face and blepharophimosis, which is now recognized as an MED12-related syndrome.
What is Lujan Fryns syndrome?
The Lujan-Fryns syndrome or X-linked mental retardation with marfanoid habitus syndrome (OMIM 309520) is a syndromal X-linked form of mental retardation (mild to moderate mental retardation), associated with tall, marfanoid stature, distinct facial dysmorphism and behavioural problems.
What is Opitz Kaveggia syndrome?
▼ Description. Opitz-Kaveggia syndrome (OKS) is an X-linked recessive mental retardation syndrome characterized by dysmorphic features, including relative macrocephaly, hypertelorism, downslanted palpebral fissures, prominent forehead with frontal hair upsweep, and broad thumbs and halluces.
What is the role of the mediator complex in transcription?
Mediator is a multiprotein complex that functions as a transcriptional coactivator in all eukaryotes. Mediator complexes interact with transcription factors and RNA polymerase II. The main function of mediator complexes is to transmit signals from the transcription factors to the polymerase.
What is Beals Hecht syndrome?
Beals-Hecht syndrome, also known as congenital contractural arachnodactyly, is caused by a defect in fibrillin as in Marfan syndrome. This syndrome is characterized by a multitude of clinical findings including arachnodactyly, narrow body habitus, scoliosis, congenital contractures, and external ear deformities.
Is Opitz-Kaveggia syndrome hereditary?
Summaries for Opitz-Kaveggia Syndrome. MedlinePlus Genetics : 43 FG syndrome is a genetic condition that affects many parts of the body and occurs almost exclusively in males.
Does the mediator complex bind to DNA?
In addition to RNA polymerase II, mediator must also associate with transcription factors and DNA. The mediator functions as a coactivator and binds to the C-terminal domain of RNA polymerase II holoenzyme, acting as a bridge between this enzyme and transcription factors.
Is mediator a coactivator?
One such coactivator, mediator, is a multi-subunit complex capable of responding to different activators. It plays an key role in activation, bridging DNA-bound activators, the general transcriptional machinery, especially RNA polymerase II, and the core promoter.
How do you get Beals Hecht syndrome?
What do you need to know about Lujan syndrome?
Summary Summary. Lujan syndrome is a condition characterized by intellectual disability, behavioral problems, and poor muscle tone (hypotonia).
Are there any disorders associated with MED12 mutations?
It is likely that more MED12 mutations will be detected in sporadic patients and X-linked families with intellectual disability and dysmorphic features as exome sequencing becomes more commonly utilized, and this overview of MED12-related disorders may help to correlate MED12 genotypes with clinical findings.
What is the function of the MED12 gene?
The MED12 gene provides instructions for making a protein called mediator complex subunit 12. As its name suggests, this protein forms one part (subunit) of the mediator complex, which is a group of about 25 proteins that work together to regulate gene activity.
How is Lujan Fryns syndrome different from Opitz-Kaveggia syndrome?
The findings indicated that Lujan-Fryns syndrome and Opitz-Kaveggia syndrome are allelic disorders. Clinically, Lujan-Fryns syndrome could be distinguished by tall stature, hypernasal voice, hyperextensible digits, and high nasal root.
