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.

This sequence change creates a premature translational stop signal (p.Arg99*) in the PROP1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PROP1 are known to be pathogenic (PMID: 9462743, 9745452). This variant is present in population databases (rs121917844, gnomAD 0.003%). This premature translational stop signal has been observed in individuals with combined pituitary hormone deficiency (PMID: 10599689, 11549703, 30266296). This variant is also known as p.Arg95*. ClinVar contains an entry for this variant (Variation ID: 8105). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
