FRA10AC1 (Fragile Site, Folic Acid Type, Rare, Fra(10)(q23.3) or FRA10A Candidate 1): FRA10AC1 is a gene linked to a rare fragile site on chromosome 10. Fragile sites are specific regions in the genome that are more prone to breakage under certain conditions. These sites can contribute to chromosomal instability and have been associated with various genetic disorders and cancers. Although the precise functions of FRA10AC1 are not fully understood, research is focused on its role in maintaining genomic stability and its potential connection to developmental disorders and disease risk.
