This sequence change replaces phenylalanine with isoleucine at codon 117 of the PROP1 protein (p.Phe117Ile). The phenylalanine residue is highly conserved and there is a small physicochemical difference between phenylalanine and isoleucine. This variant is present in population databases (rs121917840, ExAC 0.03%). This variant has been observed to segregate with pituitary hormone deficiency (PHD) in a family and has also been observed in several individuals affected with PHD (PMID: 17526936, 21132537, 9462743). ClinVar contains an entry for this variant (Variation ID: 8096). This variant has been reported to affect PROP1 protein function (PMID: 9462743). For these reasons, this variant has been classified as Pathogenic.
