GSX1
Chr 13GS homeobox 1
Also known as: GSH1, Gsh-1
GSX1 encodes a transcription factor that binds specific DNA sequences to activate gene transcription, particularly the growth hormone-releasing hormone (GHRH) gene, and plays an important role in pituitary development. Mutations cause autosomal dominant pituitary hormone deficiency with variable hormone deficiencies. The gene shows relatively low constraint to loss-of-function mutations, suggesting some tolerance to protein-truncating variants.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
The highest-scoring mechanism for this gene is dominant-negative.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
