Summary: This gene encodes a member of a family of epigenetic regulators that bind various histone-modifying enzymes and are involved in the assembly of transcription factors at specific genomic loci. Naturally occurring mutations in this gene are associated with cancer in several tissue types (breast, bladder, pancreas, ovary, prostate, and blood). This gene plays an important role in neurodevelopment, cardiac function, adipogenesis, and osteoclastogenesis. [provided by RefSeq, Feb 2017]

ASXL2 mutation was frequent in non-de novo AML1-ETO-negative AML. 6 ASXL2 mutated AML patients were studied in detail and all ASXL2-mutated de-novo AML was positive for AML1-ETO; however, other ASXL2-mutated AML belonged to non-de-novo AML and they all were negative for AML1-ETO in this study.
Title: ASXL2 mutation is recurrent in non-de novo AML1-ETO-negative acute myeloid leukemia.
after KIT and NRAS, ASXL2 is among the most frequently mutated genes in t(8;21)-positive acute myeloid leukemia (AML), occurring in almost 17% of the patients in the cohort; high incidence and the exclusivity of ASXL2 mutation in this AML subset implies its particular role as a potential co-operating event in leukemogenesis of t(8;21)-positive AML

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
