From NCBI Gene:

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]

From UniProt:

Putative Polycomb group (PcG) protein. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. They probably act via methylation of histones, rendering chromatin heritably changed in its expressibility (By similarity). Involved in transcriptional regulation mediated by ligand-bound nuclear hormone receptors, such as peroxisome proliferator-activated receptor gamma (PPARG). Acts as coactivator for PPARG and enhances its adipocyte differentiation-inducing activity; the function seems to involve differential recruitment of acetylated and methylated histone H3.

  • SHASHI-PENA SYNDROME

From UniProt:

A chromosomal aberration involving ASXL2 is a cause of therapy-related myelodysplastic syndrome. Translocation t(2;8)(p23;p11.2) with KAT6A generates a KAT6A-ASXL2 fusion protein.

Shashi-Pena syndrome (SHAPNS): An autosomal dominant syndrome characterized by delayed psychomotor development, intellectual disability of variable severity, macrocephaly, prominent eyes, arched eyebrows, hypertelorism, a glabellar nevus flammeus, neonatal feeding difficulties, and hypotonia. Some patients may also have atrial septal defect, episodic hypoglycemia, changes in bone mineral density, and/or seizures. [MIM:617190]
