Genes affected
POU4F1 (HGNC:9218): (POU class 4 homeobox 1) This gene encodes a member of the POU-IV class of neural transcription factors. This protein is expressed in a subset of retinal ganglion cells and may be involved in the developing sensory nervous system. This protein may also promote the growth of cervical tumors. A translocation of this gene is associated with some adult acute myeloid leukemias. [provided by RefSeq, Mar 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 19, 2024The c.1184A>G (p.K395R) alteration is located in exon 2 (coding exon 2) of the POU4F1 gene. This alteration results from a A to G substitution at nucleotide position 1184, causing the lysine (K) at amino acid position 395 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
