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 Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.957
• PP5: Variant 3-87260055-G-A is Pathogenic according to our data. Variant chr3-87260055-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 13609.Status of the report is no_assertion_criteria_provided, 0 stars.
