nomenclature changes

01/12/2016 Human name has changed for Entrez Gene: 2334. From AF4/FMR2 family, member 2 to AF4/FMR2 family member 2.

3/31/2022 removed synonym "fragile X mental retardation 2"

This follows a request to the NCBI to remove 'retardation' or any 'R' referencing retardation be removed from FMRP and any other terminology linked to fragile x in the gene database(s) as this is outdated and offensive terminology. See: "The Use of “Retardation” in FRAXA, FMRP, FMR1 and Other Designations" : [1].

This article was written on behalf of 17 fragile x family associations calling for the removal of 'retardation' as discriminatory and stigmatic.


summary for human AFF2 from NCBI

This gene encodes a putative transcriptional activator that is a member of the AF4\FMR2 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 this gene causing Fragile X E syndrome. Fragile X E syndrome is a form of nonsyndromic X-linked cognitive disability. In addition, this gene contains 6-25 GCC repeats that are expanded to >200 repeats in the disease state. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Jul 2016]
