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