Genes affected
HESX1 (HGNC:4877): (HESX homeobox 1) This gene encodes a conserved homeobox protein that is a transcriptional repressor in the developing forebrain and pituitary gland. Mutations in this gene are associated with septooptic dysplasia, HESX1-related growth hormone deficiency, and combined pituitary hormone deficiency. [provided by RefSeq, Jul 2008]

A published functional study suggests impaired protein function with reduced DNA binding ability and impaired ability to repress PROP-mediatd activation, however, the significance of these results are uncertain (Takagi et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; This variant is associated with the following publications: (PMID: 14558921, 26781211, 28332357, 9100579) -

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 109 of the HESX1 protein (p.Arg109Gln). This variant is present in population databases (rs768165720, gnomAD 0.02%). This missense change has been observed in individual(s) with clinical features of septo-optic dysplasia (PMID: 26781211, 28332357). ClinVar contains an entry for this variant (Variation ID: 497545). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

The missense variant p.R109Q in HESX1 (NM_003865.3) has been previously reported in heterozygous state in an affected Japanese child. Functional studies revealed a damaging effect (Takagi M et al). The variant has been submitted to ClinVar as Uncertain Significance. The missense variant c.326G>A (p.R109Q) in HESX1 (NM_003865.3) is observed in 4/18394 (0.0217%) alleles from individuals of East Asian background in the gnomAD dataset (Exome Aggregation Consortium et al., 2016), but was not seen in the homozygous state. The p.R109Q missense variant is predicted to be damaging by both SIFT and PolyPhen2. The arginine residue at codon 109 of HESX1 is conserved in all mammalian species. The nucleotide c.326 in HESX1 is predicted conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance -
