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