Genes affected

PROP1 (HGNC:9455): (PROP paired-like homeobox 1) This gene encodes a paired-like homeodomain transcription factor in the developing pituitary gland. Expression occurs prior to and is required for expression of pou domain transcription factor 1, which is responsible for pituitary development and hormone expression. Mutations in this gene have been associated with combined pituitary hormone deficiency-2 as well as deficiencies in luteinizing hormone, follicle-stimulating hormone, growth hormone, prolactin, and thyroid-stimulating hormone.

Published functional studies demonstrate a damaging effect with impaired DNA binding (PMID: 9462743); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 16131601, 10323394, 12173688, 15726414, 22024773, 21132537, 17526936, 9462743, 33098107) -

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces phenylalanine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 117 of the PROP1 protein (p.Phe117Ile). This variant is present in population databases (rs121917840, gnomAD 0.02%). This missense change has been observed in individual(s) with pituitary hormone deficiency (PHD) (PMID: 9462743, 17526936, 21132537). 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: 8096). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on PROP1 protein function. Experimental studies have shown that this missense change affects PROP1 function (PMID: 9462743). For these reasons, this variant has been classified as Pathogenic. -
