Genes affected

PBX2 (HGNC:8633): (PBX homeobox 2) This gene encodes a ubiquitously expressed member of the TALE/PBX homeobox family. It was identified by its similarity to a homeobox gene which is involved in t(1;19) translocation in acute pre-B-cell leukemias. This protein is a transcriptional activator which binds to the TLX1 promoter. The gene is located within the major histocompatibility complex (MHC) on chromosome 6. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 24, 2022

The c.89A>G (p.E30G) alteration is located in exon 1 (coding exon 1) of the PBX2 gene. This alteration results from a A to G substitution at nucleotide position 89, causing the glutamic acid (E) at amino acid position 30 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
