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.

Collection Method:clinical testing

The c.754C>T (p.L252F) alteration is located in exon 5 (coding exon 5) of the PBX4 gene. This alteration results from a C to T substitution at nucleotide position 754, causing the leucine (L) at amino acid position 252 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
