SOX1
Chr 13SRY-box transcription factor 1
The SOX1 protein is a transcription factor that keeps neural cells undifferentiated during development by suppressing neuronal differentiation and counteracting proneural proteins. Mutations in SOX1 cause microphthalmia with brain and digit anomalies, inherited in an autosomal recessive pattern. This condition affects multiple organ systems including the eyes, brain, and limbs during early development.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
Mild missense constraint
The highest-scoring mechanism for this gene is loss-of-function (haploinsufficiency).
