Fact Sheet 56|FAMILIAL HYPERCHOLESTEROLAEMIA In summary
... Since all our chromosomes come in pairs, all our genes also come in pairs. Sometimes, a gene may have a variation in the instruction that causes the gene to no longer function properly. This variation is called a mutation or pathogenic variant, and means that the product produced by the gene, called ...

Pre-Seminar Focus Questions
... Aneuploidy resulting in the loss of an entire chromosome usually results in a non-viable embryo. However, if the chromosome concerned is the X-chromosomes the embryo may live. Explain why the loss of an entire autosome is almost always lethal but the loss of the X-chromosome may not be lethal. ...

Saethre–Chotzen syndrome
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.
