SKIV2L2
The SKIV2L2 Gene: Unraveling Its Role in Human Health
Description
The SKIV2L2 gene, also known as SUPT5H, encodes a protein called Suppressor of Variegation 4-20 Homolog 2 (SUV4-20H2). This protein is involved in chromatin remodeling, a process that regulates gene expression by altering the structure of DNA. SUV4-20H2 specifically methylates histone H4 at lysine 20 (H4K20me3), which is associated with gene silencing.
Associated Diseases
Mutations in the SKIV2L2 gene have been linked to several human diseases, including:
- Intellectual disability: Mutations in SKIV2L2 can lead to a range of intellectual disability disorders, including CHARGE syndrome and Nicolaides-Baraitser syndrome.
- Autism spectrum disorder (ASD): Studies have found an increased frequency of SKIV2L2 mutations in individuals with ASD, particularly those with a history of intellectual disability.
- Congenital heart defects: Mutations in SKIV2L2 can also contribute to congenital heart defects, such as atrial septal defects (ASDs) and ventricular septal defects (VSDs).
Did you Know ?
Approximately 1 in 20,000 individuals worldwide are estimated to have a mutation in the SKIV2L2 gene, making it a relatively rare genetic condition. However, the incidence of SKIV2L2 mutations is higher in certain populations and among individuals with specific clinical features.
