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]

The c.521C>T (p.S174L) alteration is located in exon 3 (coding exon 3) of the PBX2 gene. This alteration results from a C to T substitution at nucleotide position 521, causing the serine (S) at amino acid position 174 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
