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 c.545A>T (p.N182I) alteration is located in exon 4 (coding exon 4) of the HESX1 gene. This alteration results from a A to T substitution at nucleotide position 545, causing the asparagine (N) at amino acid position 182 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
