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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 08, 2023The c.1197G>A (p.M399I) alteration is located in exon 8 (coding exon 8) of the PBX2 gene. This alteration results from a G to A substitution at nucleotide position 1197, causing the methionine (M) at amino acid position 399 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
