About POU1F1

Cytogenetic location: 3p11.2 Genomic coordinates (GRCh38): 3:87,259,404-87,276,584 (from NCBI)

This gene has 4 transcripts (splice variants), 199 orthologues, 17 paralogues and is associated with 5 phenotypes. Low expression observed in reference dataset.

Summary

This gene encodes a member of the POU family of transcription factors that regulate mammalian development. The protein regulates expression of several genes involved in pituitary development and hormone expression. Mutations in this genes result in combined pituitary hormone deficiency. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
