... Previous work in our lab showed that the LCE2B gene (one of 18 similar LCE genes) is upregulated by 1,25D. This may help repair skin after psoriasis injury. Two candidate vitamin D response element (VDRE) sequences, designated LCE2.e1 and LCE2.e3, located near the LCE2B gene were previously shown to ...

Understanding the Genetics of HHT

This is because each egg and sperm has only one copy of each gene pair, not both. But whether it is the normal or abnormal copy of the HHT g ...

Saethre–Chotzen syndrome
![](https://commons.wikimedia.org/wiki/Special:FilePath/Sutures_from_top.png?width=300)
Saethre–Chotzen syndrome (SCS), also known as Acrocephalosyndactyly type III is a rare congenital disorder associated with craniosynostosis (premature closure of one or more of the sutures between the bones of the skull). This affects the shape of the head and face, resulting in a cone-shaped head and an asymmetrical face. Individuals with SCS also have droopy eyelids (ptosis), widely spaced eyes (hypertelorism), and minor birth defects of the hands and feet (syndactyly). In addition, individuals with more severe cases of SCS may have mild to moderate mental retardation or learning disabilities. Depending on the level of severity, some individuals with SCS may require some form of medical or surgical intervention. Most individuals with SCS live fairly normal lives, regardless of whether medical treatment is needed or not.
