Genes affected
POU5F1 (HGNC:9221): (POU class 5 homeobox 1) This gene encodes a transcription factor containing a POU homeodomain that plays a key role in embryonic development and stem cell pluripotency. Aberrant expression of this gene in adult tissues is associated with tumorigenesis. This gene can participate in a translocation with the Ewing's sarcoma gene on chromosome 21, which also leads to tumor formation. Alternative splicing, as well as usage of alternative AUG and non-AUG translation initiation codons, results in multiple isoforms. One of the AUG start codons is polymorphic in human populations. Related pseudogenes have been identified on chromosomes 1, 3, 8, 10, and 12. [provided by RefSeq, Oct 2013]

The c.403G>A (p.E135K) alteration is located in exon 1 (coding exon 1) of the POU5F1 gene. This alteration results from a G to A substitution at nucleotide position 403, causing the glutamic acid (E) at amino acid position 135 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
