FMR1-AS1 gene

In molecular biology, FMR1 antisense RNA 1 (FMR1-AS1), also known as ASFMR1 or FMR4, is a is_associated_with::long non-coding RNA. The FMR1-AS1 is_associated_with::gene overlaps, and is is_associated_with::antisense to, the CGG repeat region of the is_associated_with::FMR1 gene. Its expression is upregulated in is_associated_with::fragile X syndrome premutation carriers, and silenced in patients with fragile X syndrome. FMR1-AS1 has an anti-is_associated_with::apoptotic function.
