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 exhibit increased vulnerability to breakage under certain conditions. These regions can lead to chromosomal instability and have been associated with various genetic disorders and cancers. Although the precise functions of FRA10AC1 are not completely understood, research is focused on its role in maintaining genomic stability and its potential association with developmental disorders and disease risk.
