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]

This sequence change replaces alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 158 of the POU1F1 protein (p.Ala158Pro). This variant is present in population databases (rs104893756, gnomAD 0.006%). This missense change has been observed in individual(s) with autosomal recessive pituitary hormone deficiency (PMID: 1509263). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 13604). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt POU1F1 protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects POU1F1 function (PMID: 1509263, 16263824). For these reasons, this variant has been classified as Pathogenic. -
