Genes affected

POU5F1B (HGNC:9223): (POU class 5 homeobox 1B) This intronless gene was thought to be a transcribed pseudogene of POU class 5 homeobox 1, however, it has been reported that this gene can encode a functional protein. The encoded protein is nearly the same length as and highly similar to the POU class 5 homeobox 1 transcription factor, has been shown to be a weak transcriptional activator and may play a role in carcinogenesis and eye development.

Nov 27, 2024

The c.19T>G (p.S7A) alteration is located in exon 1 (coding exon 1) of the POU5F1B gene. This alteration results from a T to G substitution at nucleotide position 19, causing the serine (S) at amino acid position 7 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
