Genes affected

PBX4 (HGNC:13403): (PBX homeobox 4) This gene encodes a member of the pre-B cell leukemia transcription factor family. These proteins are homeobox proteins that play critical roles in embryonic development and cellular differentiation both as Hox cofactors and through Hox-independent pathways. The encoded protein contains a homeobox DNA-binding domain, but specific functions of the protein have not been determined. Alternatively spliced transcript variants have been observed for this gene.

Ambry Genetics

May 10, 2022

The c.277G>A (p.V93M) alteration is located in exon 3 (coding exon 3) of the PBX4 gene. This alteration results from a G to A substitution at nucleotide position 277, causing the valine (V) at amino acid position 93 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
