Genes affected

POU1F1 (HGNC:9210): (POU class 1 homeobox 1) 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]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. There are 5 pathogenic variants in the truncated region.
• PP5: Variant 3-87260022-C-A is Pathogenic according to our data. Variant chr3-87260022-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 13607.Status of the report is no_assertion_criteria_provided, 0 stars.
