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]

The p.Gln171ValfsExtX8 variant in HESX1 has not been previously reported in indi viduals with septo-optic dysplasia but has been identified in 0.1% (10/9844) of Ashkenazi Jewish chromosomes by gnomAD (http://gnomad.broadinstitute.org). This variant is predicted to cause a frameshift altering the protein?s terminal 14 am ino acids beginning at position 171, abolishing the stop codon, and extending th e protein by 8 amino acids. It is unclear if this alteration will impact the pro tein. In summary, the clinical significance of the p.Gln171ValfsExtX8 variant is uncertain. ACMG/AMP Criteria applied: PM4. -
