Genes affected

PBX3 (HGNC:8634): (PBX homeobox 3) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in animal organ development; neuron development; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including adult locomotory behavior; dorsal spinal cord development; and regulation of respiratory gaseous exchange by nervous system process. Predicted to be located in nucleus. Predicted to be part of chromatin. [provided by Alliance of Genome Resources, Apr 2022]

The c.1088A>C (p.Q363P) alteration is located in exon 7 (coding exon 7) of the PBX3 gene. This alteration results from a A to C substitution at nucleotide position 1088, causing the glutamine (Q) at amino acid position 363 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
