Gene Gene information from NCBI Gene database.
Entrez ID 2334
Gene name ALF transcription elongation factor 2
Gene symbol AFF2
Synonyms (NCBI Gene)
FMR2FMR2PFRAXEMRX2OX19XLID109
Chromosome X
Chromosome location Xq28
Summary This gene encodes a putative transcriptional activator that is a member of the AF4FMR2 gene family. This gene is associated with the folate-sensitive fragile X E locus on chromosome X. A repeat polymorphism in the fragile X E locus results in silencing of
