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.

The c.638A>G (p.K213R) alteration is located in exon 5 (coding exon 5) of the PBX4 gene. This alteration results from a A to G substitution at nucleotide position 638, causing the lysine (K) at amino acid position 213 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
